The first substrate 31 is a light transmissive substrate, such as a glass substrate or a plastic substrate. The light-transmitting substrate is a planar substrate or a curved substrate. The planar substrate is, for example, a quadrangular substrate. The curved substrate is, for example, a circular arc curved substrate. The first substrate 31 has a surface 311. The surface 311 has a light transmissive region 312 and a mounting region 313 surrounding the light transmissive region 312. The area of the light penetration region 312 is 50% or more of the area of the surface 311 of the first substrate 31. Preferably, the area of the light penetration region 312 is 80% to 99% of the area of the surface 311 of the first substrate 31. In the first embodiment, the first substrate 31 is a flat glass substrate, has a thickness of 5mm, a length of 670mm, and a width of 480mm, and the area of the light penetration region 312 is 91.2% of the area of the surface 311 of the first substrate 31.
The second substrate 32 is spaced apart from the first substrate 31. The second substrate 32 is a light transmissive substrate, such as a glass substrate or a plastic substrate. The light-transmitting substrate is a planar substrate or a curved substrate. The planar substrate is, for example, a quadrangular substrate. The curved substrate is, for example, a circular arc curved substrate. In the first embodiment, the second substrate 32 is a flat glass substrate, has a thickness of 5mm, a length of 670mm, and a width of 480 mm.
The light reflective film 33 is located between the first substrate 31 and the second substrate 32, and connects the first substrate 31 and the second substrate 32. The light reflection film 33 is used to reflect light therein to the first substrate 31 and the second substrate 32. The light reflective film 33 includes a glue layer unit 331 for connecting the first substrate 31 and the second substrate 32, and a plurality of light reflective particles 332 distributed in the glue layer unit 331. The adhesive layer unit 331 includes at least one adhesive layer. Such as, but not limited to, an ethylene-vinyl acetate copolymer (EVA) layer, a polyvinyl butyral (PVB) layer, a Polyurethane (PU) layer, a Polyimide (PI) layer, or a silicone resin (silicone) layer. The light reflective particles 332 have a particle size ranging from 0.1 μm to 2.5 μm. The light reflective particles 332 may be the same or different, and are for example, but not limited to, metal particles, metal composite particles, or alloy particles, etc. Such as, but not limited to, silver, aluminum, titanium, platinum, or nickel, etc. Such as, but not limited to, aluminum powder with silver-plated surface. Such as, but not limited to, steel. In the first embodiment, the light reflecting film 33 has a thickness of 1.2mm and includes an ethylene-vinyl acetate copolymer layer as an adhesive layer unit 331 and a plurality of light reflecting particles 332 distributed in the ethylene-vinyl acetate copolymer layer, the light reflecting particles 332 are aluminum powder with silver-plated surface, and the amount of the light reflecting particles 332 is 300 mg based on 1 kg of the total amount of the light reflecting film 33, that is, the concentration of the light reflecting particles 332 is 300 ppm.
The solar chip 34 is embedded in the light reflecting film 33, surrounds the light transmitting region 312 of the surface 311 of the first substrate 31, is distributively disposed on the mounting region 313 of the surface 311 of the first substrate 31, and is used to convert light into electricity. Compared with the solar chip 34 which is arranged on the side surface 30 of the laminated body 3 in a sticking way through the adhesive material, the solar chip 34 of the invention is embedded in the light reflection film 33, so that the problem that the solar chip 34 is damaged due to collision when the solar window is installed can be avoided, and the problem of reflection loss of the interface in the process of transmitting light to the solar chip 34 due to the existence of the adhesive material can be reduced, thereby improving the power generation efficiency. Such as a polycrystalline silicon solar chip, a single crystalline silicon solar chip, or a group III-V solar chip, among others. In the first embodiment, the number of the solar chips 34 is 14, the solar chips are polycrystalline silicon solar chips, the size is 155mm × 13mm, and the power generation conversion efficiency is 17.5%. The distance 6 between the long side of each solar chip 34 and the periphery of the first substrate 31 is 5 mm. It should be noted that the number of the solar chips 34 is not limited to 14, and may be one, two, three, five, ten, etc., and may be adjusted according to the installation size of the window or the requirements of the installation environment. It should be noted that the solar chip 34 is not limited to be disposed around the light transmissive region 312, and may be disposed on the mounting region 313 and located on at least one side of the light transmissive region 312, for example, disposed on the mounting region 313 and concentrated on the same side (e.g., left side or right side) of the light transmissive region 312, disposed on the mounting region 313 and located on two sides (e.g., upper side and lower side or left side and right side) of the light transmissive region 312, or disposed on the mounting region 313 and located on three sides (e.g., left side, right side and lower side) of the light transmissive region 312.

The first metal strip 351 is, for example, an aluminum metal strip. Each metal strip 351 connects every two adjacent solar chips 34 to form a serial circuit. In the serial circuit state, the second metal strip 352 is connected to the first solar chip 34 and the last solar chip 34 respectively, and extends out of the laminate 3.
The heat insulation unit 36 is disposed on the second substrate 32 opposite to the light reflection film 33. The heat insulation unit 36 is a heat insulation layer for reflecting or absorbing infrared light to reduce the indoor temperature, or a light shielding layer for reducing light entering the indoor to reduce the indoor temperature. The heat insulation layer comprises a transparent conductive layer and a composite film of polyethylene terephthalate. The shading layer is an electrochromic shading layer.
The specular reflection unit 4 is disposed on at least one side surface 30 of the laminate 3, and is configured to focus and reflect light in the laminate 3 to the solar chip 34. The specular reflection unit 4 is, for example, a concave lens. In the first embodiment, the specular reflection unit 4 is a specular reflection film, and surrounds the four sides 30 of the laminate 3. In the first embodiment, the thickness of the specular reflection film is 20 μm.
Referring to fig. 4, a second embodiment of the solar window of the present invention differs from the first embodiment mainly in that: in the second embodiment, the heat insulating unit 36 is not provided. In the second embodiment, the laminate 3 of the solar window has a light transmittance of 45% and a haze of 4.9%, and the power generation efficiency of the solar window is about 2.6%.
The solar window is suitable for being installed on a building or a vehicle. The solar window of the present invention can be used by efficiently converting light into electricity through the solar chip 34 and supplying the electricity to electric products such as electric lamps or the electrochromic light shield layer of the heat insulation unit 36.
When the solar window is installed, the first substrate 31 of the solar window faces outdoors and the second substrate 32 faces indoors. When light 5 from outdoors (e.g., light irradiated by the sun or light reflected by an object) enters the light reflection film 33 via the first substrate 31, a part of the light 5 penetrates the light reflection film 33 and enters the second substrate 32, and another part is reflected by the light reflection particles 332 of the light reflection film 33 and enters again into the first substrate 31. The other part of the light 5 will be reflected and oscillated back and forth in the first substrate 31 and the second substrate 32, and transmitted to the solar chip 34, and finally collected in the solar chip 34 and converted into electricity through the solar chip 34.
In summary, the solar window of the present invention does not diffuse light due to the design of the light reflective film 33, and reduces the occurrence of light fogging due to light splitting caused by diffusion in the solar window, so that the appearance of the window can be clearly seen, thereby achieving the object of the present invention.
