Referring to fig. 2, the housing 100 includes a solar cell module 110, a decoration unit 120, and a transparent cover 130. The decoration unit 120 is disposed on the solar cell module 110. The overall transmittance of the decoration unit 120 is 30% or more. The transparent cover plate 130 is disposed on a side of the decoration unit 120 away from the solar cell module 110.

The housing 100 comprises the solar cell module 110, the decoration unit 120 and the transparent cover plate 130, because the solar cell module 110 is located at one side of the decoration unit 120 far away from the transparent cover plate 130, the overall appearance effect of the side of the transparent cover plate 130 far away from the decoration unit 120 can be ensured, and the decoration unit 120 has a decoration effect on the housing 100, so that the overall appearance effect of the side of the transparent cover plate 130 far away from the solar cell module 110 is better, furthermore, the overall transmittance of the decoration unit 120 is more than 30%, and the solar cell module 110 has a certain shielding effect, so that the solar cell module 110 is not easy to observe from one side of the transparent cover plate 130 far away from the solar cell module 110, and light can penetrate through the decoration unit 120 to irradiate to the solar cell module 110 more, so as to improve the light absorption of the solar cell module 110, and an electronic device comprising the housing 100 can be charged through the solar cell module 110, the standby time of the electronic equipment is prolonged.

A solar cell module is a photoelectric semiconductor sheet that directly generates electricity using sunlight. The solar cell can output voltage instantly and generate current under the condition of a loop as long as the solar cell is illuminated under a certain illumination condition. Physically referred to as solar Photovoltaic (abbreviated PV), Photovoltaic for short. The power generation principle of the solar cell is as follows: sunlight irradiates on a semiconductor P-N junction of a solar cell to form a new hole-electron pair, under the action of an electric field built in the P-N junction (at the interface of a P-type semiconductor and an N-type semiconductor), photo-generated holes flow to a P region (namely, a hole region and can absorb electrons), photo-generated electrons flow to an N region (namely, an electron region and can release electrons), and current is generated after a circuit is switched on. This is the working principle of photovoltaic solar cells, also called photovoltaic effect. Therefore, the solar cell function can be realized as long as the material has the photovoltaic effect. Among them, there are two kinds of carriers, that is, holes in the valence band and electrons in the conduction band, and a semiconductor mainly based on electron conduction is called an N-type semiconductor, and a semiconductor mainly based on hole conduction is called a P-type semiconductor.

In one embodiment, the solar cell module 110 is a flexible solar cell. The flexible solar cell is one of thin-film solar cells, and has the advantages of advanced technology, excellent performance, low cost and wide application. The solar energy backpack can be applied to solar backpacks, solar open canopies, solar flashlights, solar automobiles, solar sailing boats and even solar airplanes. The solar cell module 110 is a crystalline silicon solar cell, a compound semiconductor solar cell, an organic solar cell, a dye-sensitized solar cell, or the like.

The silicon solar cell is a monocrystalline silicon solar cell, a polycrystalline silicon solar cell, an amorphous silicon solar cell or a nanocrystalline silicon thin-film solar cell. Among them, the thickness of an amorphous silicon (a-Si) flexible battery is 1/300 of a crystalline silicon battery. The conversion efficiency of the amorphous silicon flexible battery reaches 8% -8.5%.

A selenium photovoltaic cell is a semiconductor device that directly converts light energy into electrical energy. The CIGS thin-film solar Cell (CIGS) has few internal defects, stable performance and a service life of 25 years. In the using process of the copper indium gallium selenide thin-film solar cell, the defects generated in the application process can be repaired by the movement of copper ions, so that the performance of the copper indium gallium selenide thin-film solar cell is continuously improved, which is just opposite to the light-induced degradation effect or S-W effect (Staebler-Wronski effect) of amorphous silicon.

The compound semiconductor solar cell is a solar cell produced using a compound semiconductor as a base. The compound semiconductor solar cell is mainly a cadmium sulfide solar cell, a selenium indium copper solar cell, a cadmium telluride solar cell, a gallium arsenide solar cell, an indium phosphide solar cell or the like.

In the cadmium telluride (CdTe) thin film solar cell, the cadmium telluride is a II-IV group compound, is a direct band gap semiconductor, has strong light absorption, has a forbidden band width well matched with the ground solar spectrum, is very suitable for photoelectric energy conversion, can absorb more than 95 percent of sunlight, and is a good solar cell material. The cadmium telluride thin film photovoltaic cell has low production cost, stable performance and higher conversion efficiency than a silicon-based thin film cell, and the large-scale mass production of the cadmium telluride thin film photovoltaic cell has high cost performance.

An Organic Photovoltaic (OPV) solar cell, i.e., a solar cell with a core portion made of organic material, mainly uses an organic substance with photosensitive property as a semiconductor material, and generates voltage to form current by using a photovoltaic effect, thereby realizing the effect of solar power generation. The organic semiconductor absorption medium of an organic solar cell is usually formed by mixing a donor material and an acceptor material. Donor materials are good at donating electrons, absorbing holes, and being electropositive when mixed, conjugated polymers (conjugated polymers) are typical donor materials. The acceptor material is good at absorbing electrons and giving out holes, and has electronegativity after mixing. Fullerene (C60) is a typical acceptor material. Organic solar cells have the advantages of low cost, light weight, inherent flexibility of the active layer, and the like. The flexible active layer is the most outstanding characteristic of the organic solar cell, and the organic solar cell is more suitable for manufacturing flexible devices than a silicon-based solar cell and an inorganic semiconductor thin-film solar cell.

The dye-sensitized solar cell is a novel solar cell which is developed by simulating the photosynthesis principle. The dye-sensitized solar cell is formed by titanium dioxide (TiO)₂) The surface is coated with a layer of chlorophyll dye to simulate the photosynthesis of plants in nature by utilizing solar energy, and the solar energy is converted into electric energy.

In the illustrated embodiment, the first electrode 113 is disposed between the substrate 111 and the photoelectric functional layer 115.

The second electrode 117 is used for conduction to draw current. Further, the second electrode 117 is a back electrode. Further, the second electrode 117 is an Al — Ni material. The Al-Ni material is a composite material of aluminum and nickel. In the illustrated embodiment, the second electrode 117 is disposed on a side of the photoelectric functional layer 115 remote from the substrate 111.

It should be noted that the Al — Ni material is a composite material of aluminum and nickel commonly used in the art, and is not described herein again. It should be noted that the brightness enhancement effect of the decoration unit 120 can be improved by adjusting the material of the second electrode 117 to make the second electrode 117 have higher reflectivity. The material of the second electrode 117 is not limited to Al — Ni, and may be other materials commonly used in the art.

The second electrode 117 is not limited to be a back electrode, and may be a front electrode. Accordingly, the first electrode 113 is not limited to be a front electrode, but may be a rear electrode. The first electrode 113 is not limited to be disposed between the substrate 111 and the photoelectric functional layer 115, and may be disposed on a side of the photoelectric functional layer 115 away from the substrate 111, or may be disposed at another position, and may be disposed as needed as long as the first electrode 113 and the photoelectric functional layer 115 are electrically connected.

In one embodiment, the thickness of the solar cell module 110 is 50 μm to 100 μm. This arrangement is advantageous in reducing the thickness of the housing 100, so that the electronic device is more lightweight and thinner. The thickness of the solar cell module 110 is not limited to the above-described range, and may be set as needed.

In one embodiment, the solar cell module 110 is opposite to the display module 100 a. Further, the second electrode 117 is opposite to the display module 100 a.

In one embodiment, the solar cell module 110 is electrically connected to the control circuit mechanism. This arrangement enables power supply to the control circuit mechanism through the solar cell module 110. Further, the solar cell module 110 is electrically connected to the control circuit mechanism through a circuit board or a contact. Further, the Circuit board is an FPC (flexible printed Circuit). In the illustrated embodiment, the control circuit mechanism is a motherboard. The control circuit mechanism is electrically connected to both the first electrode 113 and the second electrode 117.

In one embodiment, the decorative unit 120 has an overall transmittance of 30% to 90%. By the arrangement, the decoration unit 120 can well shield the solar cell module 110, so that the solar cell module 110 is not easy to observe from one side of the decoration unit 120 away from the solar cell module 110, and light can be incident into the solar cell module 110 through the decoration unit 120, so that light absorption of the solar cell module 110 is improved, and the power generation effect of the solar cell module 110 is ensured.

In one embodiment, the decorative element 120 is a decorative element without a cover-less ink layer.

Generally, through the decoration unit that has the printing ink layer at the bottom of setting on the apron, printing ink layer at the bottom of the lid keeps away from the apron setting so that the decorative effect of decorating the unit shows, obtains the casing that has better outward appearance effect to promote electronic equipment's outward appearance effect. Some studies ensure the appearance of the electronic device by providing the cover bottom ink layer on the solar cell panel. However, the overall transmittance of the decoration unit is low, which affects the light absorption of the solar cell panel and is not beneficial to the photoelectric effect of the solar cell panel. In this research, the decoration unit 120 is set as a decoration unit without a bottom-covering ink layer, so that the decoration unit 120 has a high overall transmittance, and light can penetrate through the decoration unit 120 to irradiate the solar cell module 110 more, so as to improve light absorption of the solar cell module 110, and prolong the standby time of the electronic device including the housing 100, and because the overall transmittance of the solar cell module 110 is low, the solar cell module 110 can serve as a bottom-covering layer of the decoration unit 120, so that the decoration effect of the decoration unit 120 is shown, and the housing 100 has a good appearance effect.

Further, the decoration unit 120 is a decoration unit without a substrate. The "substrate" is a base or a carrier, and the substrate can carry a member having a decorative effect. For example, if the decorative component is a textured layer, the substrate can carry the textured layer. In the present study, the decoration unit 120 is configured as a decoration unit without a substrate, so that the decoration unit 120 uses the solar cell module 110 as a carrier, which is beneficial to reducing the thickness of the housing 100. Further, the thickness of the decoration unit 120 is 25 μm to 30 μm. Such an arrangement is advantageous for reducing the thickness of the housing 100 to satisfy the requirement of light weight of the electronic device.

Further, the decoration unit 120 is disposed on a side of the substrate 111 away from the first electrode 113. The arrangement enables the decoration unit 120 to use the substrate 111 as a carrier, so that the decoration unit 120 and the solar cell module 110 share the substrate 111, which is beneficial to reducing the thickness of the housing 100.

Referring to fig. 4, the decoration unit 120 includes a decoration film layer. The decorative film layer has a decorative effect. The decorative film layer includes a texture layer 122. The texture layer 122 is disposed on the solar cell module 110. The texture layer 122 is disposed to ensure that light can be transmitted through the decoration unit 120 and enter the solar cell module 110, and the housing 100 has a texture effect, so as to increase the appearance of the housing 100. The texture layer 122 is directly disposed on the solar cell module 110.

In one embodiment, the textured layer 122 includes a plate-like body 122a and a plurality of parallel ribs 122 b. The plate-like body 122a is disposed on a side of the base 111 away from the first electrode 113. The plurality of convex strips 122b are arranged on the side of the plate-shaped body 122a far away from the base 111. By arranging the plurality of parallel convex strips 122b on the plate-shaped body 122a, the texture effect of the texture layer 122 has a depth sense, and is more three-dimensional, so that the shell 100 is more attractive.

The plate-shaped body 122a is used for carrying the protruding strips 122 b. Further, the material of the plate-shaped body 122a is UV glue or UV resin.

The shape of a cross section of each convex strip 122b in a direction perpendicular to the extending direction of the convex strip 122b is triangular. This arrangement provides the textured layer 122 with a sense of depth. Further, each convex strip 122b is a triangular prism shape. One side surface of each convex strip 122b faces the plate-like body 122 a. Further, each of the ribs 122b is equal in height. This arrangement enables the texture layer 122 to exhibit a uniform texture effect. Specifically, the material of the protruding strips 122b is UV glue or UV resin.

The convex strips 122b are not limited to triangular prism shapes, and the convex strips 122b may have other shapes, for example: a dog-leg shape, a wavy shape, or a circular arc shape, etc. The shape of the cross section of the convex portion 122b perpendicular to the extending direction of the convex portion 122b is not limited to a triangle, and may be other shapes, for example, a semicircular shape.

Further, the plurality of protruding strips 122b are sequentially spliced in a direction perpendicular to the first direction. The first direction is perpendicular to the extending direction of the convex strips 122 b. It should be noted that the plurality of protruding strips 122b are not limited to be sequentially spliced in the direction perpendicular to the first direction; the plurality of convex strips 122b can also be arranged at intervals; it is also possible to arrange some of the ribs 122b at intervals and splice some of the ribs 122 b.

It should be noted that the decoration unit 120 is not limited to the above-mentioned structure, and the decoration unit 120 may be a decoration film commonly used in the art.

The transparent cover 130 has opposing first and

second surfaces

131 and 133. Further, the transparent cover 130 is a curved cover. The first surface 131 is convex. The second surface 133 is concave. The transparent cover plate 130 is disposed on a side of the decoration unit 120 away from the solar cell module 110. And the second surface 133 is opposite to the decoration unit 120. The transparent cover 130 is not limited to a curved cover, and may be a flat cover, and may be provided as needed. When the transparent cover 130 is a planar cover, the first surface 131 and the second surface 133 are both planar.

In one embodiment, the transparent cover 130 is a transparent glass cover. Further, the transparent cover plate 130 is a 3D (3Dimensional) transparent glass plate. The transparent cover 130 is not limited to a transparent glass cover, and may be another transparent cover, for example, a transparent plastic cover.

In one embodiment, the transparent cover plate 130 and the decoration unit 120 are bonded. Further, the housing 100 further includes an adhesive layer 140. The adhesive layer 140 is positioned between the transparent cover plate 130 and the decoration unit 120, and adheres the transparent cover plate 130 and the decoration unit 120. In the illustrated embodiment, an adhesive layer 140 is positioned between the transparent cover sheet 130 and the textured layer 122.

Further, the material of the Adhesive layer 140 is optical Clear Adhesive (OCA Adhesive). The material of the adhesive layer 140 is not limited to optical glue, and may be other adhesives having high transmittance or substantially not affecting light transmission through the adhesive layer 140 and emitted to the solar cell module 110 in the art.

In one embodiment, the adhesive layer 140 has a thickness of 20 μm to 40 μm. This arrangement makes the transparent cover 130 and the decoration unit 120 more firmly coupled. It is understood that the adhesive layer 140 may be omitted.

The housing 100 comprises the solar cell module 110, the decoration unit 120 and the transparent cover plate 130, because the solar cell module 110 is located at one side of the decoration unit 120 far away from the transparent cover plate 130, the overall appearance effect of the side of the transparent cover plate 130 far away from the decoration unit 120 can be ensured, and the decoration unit 120 has a decoration effect on the housing 100, so that the overall appearance effect of the side of the transparent cover plate 130 far away from the solar cell module 110 is better, furthermore, the overall transmittance of the decoration unit 120 is more than 30%, and a certain shielding effect is provided for the solar cell module 110, so that the solar cell module 110 is not easy to observe from one side of the transparent cover plate 130 far away from the solar cell module 110, and light can be more transmitted through the transparent cover plate 130 and the decoration unit 120 to the solar cell module 110, so as to improve the light absorption of the solar cell module 110, the electronic device including the housing 100 can be charged by the solar cell module 110, and the standby time of the electronic device can be prolonged. The case 100 can improve light absorption of the solar cell module 110 while ensuring the overall appearance effect.

Furthermore, in the housing 100, the decoration unit 120 is configured as a decoration unit without a cover bottom ink layer, so that the decoration unit 120 has a high overall transmittance, and light can transmit more through the decoration unit 120 to the solar cell module 110, so as to improve light absorption of the solar cell module 110, and prolong the standby time of the electronic device including the housing 100, and further, because the transmittance of the solar cell module 110 is low, the solar cell module 110 can be used as a cover bottom layer of the decoration unit 120, so that the decoration effect of the decoration unit 120 is shown, and the housing 100 has a good appearance effect.

Furthermore, the decoration unit 120 of the housing 100 is a decoration unit without a substrate, so that the decoration unit 120 can use the solar cell module 110 as a carrier, which is beneficial to reducing the thickness of the housing 100 to meet the requirement of light weight of electronic products.

Research finds that the standby time of the electronic equipment is prolonged by arranging the solar panel outside the electronic equipment. However, this arrangement exposes the solar cell panel to wear, which is not conducive to long-term use. In the electronic device, the solar cell module 110 is disposed between the transparent cover 130 and the decoration unit 120, and the display module 100a is disposed opposite to the solar cell module 110, so that the solar cell module 110 can be protected, the solar cell module 110 is prevented from being worn, and the service lives of the housing 100 and the electronic device are prolonged.

Research finds that the solar cell panel can be prevented from being worn by arranging the solar cell panel inside the shell of the electronic equipment. However, in order to ensure light absorption of the solar cell panel, the housing needs to be provided to be transparent. At this moment, can see solar cell panel through the casing, influence the whole effect of outward appearance of electronic equipment. In the electronic device, the decoration unit 120 is disposed between the transparent cover plate 130 and the solar cell module 110 to prevent the solar cell module 110 from being worn, and the overall transmittance of the decoration unit 120 is greater than 30%, so that the overall appearance effect of the electronic device can be ensured, the light absorption of the solar cell module 110 can be improved, and the standby time of the electronic device can be prolonged.

Research finds that the polycrystalline silicon solar cell is arranged between the transparent cover plate and the decorative membrane to ensure the absorption of the polycrystalline silicon solar cell to light. However, since the polycrystalline silicon solar cell is opaque or has very low transmittance, the appearance effect of the decorative film is difficult to be revealed, so that the effect of texture or color cannot be exhibited. In the electronic device, the casing 100 is provided with the decoration unit 120 between the transparent cover 130 and the solar cell module 110, and the overall transmittance of the decoration unit 120 is more than 30%, so that more light can pass through the decoration unit 120 and irradiate to the solar cell module 110 to generate electric energy, the decoration effect of the decoration unit 120 can be presented, and the appearance expressive force of the casing 100 and the electronic device is improved.

In summary, in the housing 100 of the electronic device, the decoration unit 120 and the solar cell module 110 are integrated, so that the appearance performance of the electronic device can be improved, the electronic device including the housing 100 can be powered by solar energy irradiation, the standby time of the electronic device can be prolonged, the trouble that the electronic device is short of power in outdoor activities can be solved, the user experience of consumers can be improved, and the electronic device is more competitive.

It is understood that the decorative film layer is not limited to including the texture layer 122, and in other embodiments, the decorative film layer does not have a texture layer.
