Referring to fig. 1 to 3, a display device 10 with solar cell traces includes a display panel 100 and a thin film solar panel 200. The thin film solar panel 200 is disposed on the display panel 100 in an overlapping manner. For example, the thin film solar panel 200 may be attached to the display surface of the display panel 100 through an Adhesive layer (not shown), such as an Optically Clear Adhesive (OCA), an aqueous Adhesive, or an Optically Clear Resin (OCR), but not limited thereto.

The display panel 100 has a display area DA and a peripheral area PA other than the display area DA. The display panel 100 includes a substrate 110, a light-shielding pattern layer 120, and a plurality of display pixels PX. The substrate 110 may be made of glass, quartz, polymer (e.g., polyimide, polycarbonate), or other suitable substrate materials. The light-shielding pattern layer 120 is disposed on the substrate 110 and has a plurality of openings 120a in the display area DA. The display pixels PX are disposed in the display area DA and respectively overlap the openings 120 a. The material of the light-shielding pattern layer 120 includes a metal material, a black resin material, or other suitable opaque materials.

The plurality of display pixels PX are arranged in a plurality of pixel rows PXR and a plurality of pixel columns PXC in the direction X and the direction Y, respectively. That is, the display pixels PX are arranged in an array. In the present embodiment, the display panel 100 is, for example, a liquid crystal display panel or other suitable non-self-luminous display panel. Also as a result, the display device 10 with solar cell traces may also optionally include a backlight module (not shown). However, the present invention is not limited thereto, and according to other embodiments, the display panel 100 may also be a micro light emitting diode (micro-LED) panel, a sub-millimeter light emitting diode (mini-LED) panel, or other suitable self-luminous display panel.

Further, the thin film solar panel 200 includes a transparent substrate 210 and a plurality of solar cell traces 220. The light-transmitting substrate 210 has a surface 210s facing the display panel 100. The material of the transparent substrate 210 includes glass, transparent resin (e.g., polyethylene terephthalate, polyethylene naphthalate, polycarbonate, polyether, or polyimide), or other suitable transparent material. The solar cell traces 220 are arranged on the surface 210s of the transparent substrate 210 at intervals and overlapped with the display area DA of the display panel 100. More specifically, the thin-film solar panel 200 of the present embodiment is a clad-plate type thin-film solar panel, and the external ambient light is incident into the thin-film solar panel 200 from a surface of the transparent substrate 210 at a side where the solar cell traces 220 are not disposed.

It should be noted that the solar cell traces 220 each extend in a direction ED, and the direction ED is not parallel or perpendicular to the arrangement direction (e.g., the direction X and the direction Y) of the plurality of display pixels PX. In the present embodiment, the display device 10 is suitable for being viewed by the user USR along a viewing direction VDa (e.g. three o' clock direction in fig. 3), which has an angle Aa (e.g. 90 degrees) with the direction X (i.e. the arrangement direction of the pixel columns PXC), and an angle Ba with the extending direction of the solar cell traces 220. The following relation is satisfied by the included angle Aa and the included angle Ba: ba of 20-Aa or more and 60-Aa or less can prevent Moire Pattern (Moire Pattern) generated when the display panel 100 and the thin film solar panel 200 are overlapped, which is helpful for improving the display quality of the display device 10 with the solar cell wiring.

More specifically, the included angle Ba between the extending direction of the solar cell traces 220 and the viewing direction VDa of the display panel 100 may be between-70 degrees (i.e., the included angle B2a in fig. 3) and-30 degrees (i.e., the included angle B1a in fig. 3), such as-52 degrees. It should be noted that the negative value of the included angle Ba represents that the extending direction of the solar cell trace 220 of the present embodiment is obtained by rotating clockwise by 52 degrees with respect to the viewing direction VDa. From another perspective, an included angle Ca is formed between the extending direction of the solar cell trace 220 and the direction X (i.e., the arrangement direction of the pixel columns PXC), and the absolute value of the included angle Ca may be between 20 degrees and 60 degrees (i.e., the included angle Ca satisfies 20 degrees ≦ Ca ≦ 60 degrees), for example, 38 degrees.

In the embodiment, the solar cell trace 220 includes a first electrode layer E1, a second electrode layer E2, and a photoelectric conversion layer CL. The photoelectric conversion layer CL is disposed between the first electrode layer E1 and the second electrode layer E2. The first electrode layer E1 is located between the light-transmitting substrate 210 and the photoelectric conversion layer CL. It is particularly noted that, since the external ambient light is incident from the side of the transparent substrate 210 away from the solar cell trace 220, the first electrode layer E1 and the second electrode layer E2 are a transparent electrode layer and a reflective electrode layer, respectively. The material of the light-transmitting electrode layer includes metal oxides, such as: indium tin oxide, indium zinc oxide, aluminum tin oxide, aluminum zinc oxide, or other suitable oxide, or a stack of at least two of the foregoing.

On the other hand, the thin-film solar panel 200 further includes a solar cell periphery 230 disposed on the surface 210s of the transparent substrate 210 and overlapping the periphery PA of the display panel 100 in the normal direction (e.g., the direction Z) of the substrate 110. Unlike the solar cell traces 220 located in the display area DA, the solar cell periphery 230 may entirely cover the peripheral area PA of the display panel 100 to increase the photoelectric conversion area of the thin film solar panel 200.

For example, in the present embodiment, the solar cell periphery 230 may surround the plurality of solar cell traces 220 and electrically connect the plurality of solar cell traces 220, but not limited thereto. In an embodiment not shown, the peripheral area PA of the display area DA of the display panel 100 may be overlapped with the solar cell periphery of the thin film solar panel.

Similar to the solar cell trace 220, the solar cell periphery 230 may include a first electrode layer E1 ', a second electrode layer E2 ', and a photoelectric conversion layer CL '. The photoelectric conversion layer CL ' is disposed between the first electrode layer E1 ' and the second electrode layer E2 '. The first electrode layer E1 'is located between the light-transmitting substrate 210 and the photoelectric conversion layer CL'. It is particularly noted that, since the external ambient light is incident from the side of the transparent substrate 210 away from the solar cell trace 220, the first electrode layer E1 'and the second electrode layer E2' are a transparent electrode layer and a reflective electrode layer, respectively. The material of the light-transmitting electrode layer includes metal oxides, such as: indium tin oxide, indium zinc oxide, aluminum tin oxide, aluminum zinc oxide, or other suitable oxide, or a stack of at least two of the foregoing. The material of the reflective electrode layer includes aluminum, silver, chromium, the above alloys, the above combinations, or other metal materials with high reflectivity.

The material of the photoelectric conversion layer CL' is, for example, amorphous silicon (a-Si), but is not limited thereto. In other embodiments, the material of the photoelectric conversion layer CL' may also be single crystal silicon, polysilicon, copper indium gallium selenide, cadmium antimonide, or a combination thereof. In detail, the photoelectric conversion layer CL' includes a first extrinsic semiconductor layer 231, an intrinsic semiconductor layer 232, and a second extrinsic semiconductor layer 233. The first extrinsic semiconductor layer 231 has a first doping type, the second extrinsic semiconductor layer 233 has a second doping type, and the first and second doping types are each one of a P-type and an N-type. For example, in the present embodiment, the first extrinsic semiconductor layer 231 may be a P-type semiconductor layer, and the second extrinsic semiconductor layer 233 may be an N-type semiconductor layer.

From another perspective, in the present embodiment, the material of the plurality of solar cell traces 220 and the material of the solar cell periphery 230 are optionally the same. That is, the solar cell traces 220 and the solar cell periphery 230 may belong to the same film layer, but not limited thereto.

Further, the thin film solar panel 200 may further include a protection layer 240 disposed between the plurality of solar cell traces 220 and covering the surface E2s of the second electrode layer E2 facing away from the transparent substrate 210. The material of the protection layer 240 may be an inorganic material (e.g., silicon nitride, silicon dioxide, or aluminum oxide), an organic material (e.g., pentacene, diethylene glycol dimethyl ether, or polyimide), or a combination thereof, or other suitable light-transmitting materials. For example, when the material of the protection layer 240 is an inorganic material, it has the advantages of isolating water and oxygen and reducing electric leakage; when the material of the passivation layer 240 is an organic material, it has a smaller parasitic capacitance and a better flatness.
