Detailed Description
The invention will be further explained with reference to the drawings.
Fig. 1 is a schematic structural diagram of a photovoltaic power generation apparatus 100 according to an embodiment of the present invention; fig. 2 is a partially enlarged view of the photovoltaic power generation apparatus 100 shown in fig. 1. As shown in fig. 1 and 2, the photovoltaic power generation device 100 includes a back sheet 1, a transparent front sheet 2, a thin film solar cell panel 3, an encapsulation adhesive film 4, and a light reflection structure. Wherein the transparent front plate 2 is opposite to the back plate 1. The thin-film solar cell panel 3 is provided between the transparent front plate 2 and the back plate 1, and includes a plurality of photoelectric conversion units connected in series/parallel and arranged in an array form. The packaging adhesive film 4 is arranged between the transparent front plate 2 and the thin-film solar cell panel 3. The light reflection structure includes a first reflection member 5a and/or a second reflection member 5b, and the first reflection member 5a and/or the second reflection member 5b can reflect the received light onto the photoelectric conversion unit so that the photoelectric conversion unit can generate more electric power. Wherein the first reflective member 5a is provided between the transparent front plate 2 and the back plate 1 and adjacent to the thin film solar cell panel 3. The second reflecting member 5b is embedded in the packaging adhesive film 4, and the orthographic projection of the second reflecting member 5b on the back plate 1 completely falls into the orthographic projection of the gap between the photoelectric conversion units on the back plate 1.
The photovoltaic power generation device 100 and the manufacturing method thereof of the present invention add the first reflection member 5a and/or the second reflection member 5b, wherein the first reflection member 5a is arranged at a position between the transparent front plate 2 and the back plate 1 and adjacent to the thin-film solar cell panel 3, so that the first reflection member 5a is a part or the whole of the light reflection structure, and receives light in this non-power generation region and reflects it onto the photoelectric conversion unit, thereby improving the photoelectric conversion efficiency of the photovoltaic power generation device 100. Similarly, the second reflecting member 5b is embedded in the encapsulant film 4 and disposed above the gap between the photoelectric conversion units, so that the second reflecting member 5b serves as another part or all of the light reflecting structure, and receives and reflects light onto the photoelectric conversion units in this non-power generation region, thereby improving the photoelectric conversion efficiency of the photovoltaic power generation apparatus 100. The photovoltaic power generation device 100 is simple in structure, easy to assemble, safe and reliable to use, and convenient to implement, popularize and apply.
According to an embodiment of the present invention, the first and second reflecting members 5a and 5b each comprise at least one reflecting plane. Although a curved surface may also be used to reflect light and facilitate photoelectric conversion, since the difficulty of constructing the curved surface is high, it is recommended to select a plane having a lower construction cost, that is, the reflecting plane can reduce the manufacturing cost thereof without affecting the light reflecting effect of the first and second reflecting members 5a and 5 b. Through a large number of experiments, it is verified that when an angle between the reflection plane of the first reflection member 5a and the transparent front plate 2 is an acute angle, and an included angle between the reflection plane of the second reflection member 5b and the transparent front plate 2 is an acute angle, the sum of light received by the thin-film solar cell panel 3 and reflected by the reflection plane is maximized.
In the present embodiment, the first and second reflecting members 5a and 5b are each triangular prism-shaped. More preferably, the first reflecting member 5a and the second reflecting member 5b are both made of epoxy resin doped with glass frit.
In the present embodiment, the back sheet 1 and the transparent front sheet 2 are each one of glass, polymethyl methacrylate, and polyethylene terephthalate, and the back sheet 1 has a thickness of 2mm to 6mm and the transparent front sheet 2 has a thickness of 2mm to 6 mm. The material of the encapsulant film 4 is one of Ethylene-Vinyl Acetate Copolymer (EVA) and Polyvinyl Butyral (PVB), and the thickness of the encapsulant film is 0.5mm to 1 mm.
In the present embodiment, the thin film solar cell panel 3 is selected as a copper indium gallium selenide thin film solar cell panel. That is, in the thin-film solar cell panel 3, the photoelectric conversion unit includes a substrate 311, a back electrode 312 provided on the substrate 311, a cigs light absorbing layer 313 provided on the back electrode 312, a buffer layer 314 provided on the cigs light absorbing layer 313, and a front electrode 315 provided on the buffer layer 314. In any of the thin-film solar cell panels 3, all the photoelectric conversion units share the same substrate 311. The substrate 311 may be selected from one of soda lime glass, stainless steel, and polyimide. The material of the back electrode 312 includes molybdenum, titanium, tungsten, and/or aluminum. The material of the buffer layer 314 includes titanium dioxide, cadmium sulfide, or zinc sulfide. Aluminum-doped zinc oxide (AZO) is preferred as the material of the front electrode 315 because the aluminum-doped zinc oxide (AZO) has high visible light transmittance, high chemical stability, abundant material sources, and low price. The CIGS light absorption layer 313 and the buffer layer 314 can jointly form a PN junction, so that the photoelectric conversion unit can complete photoelectric conversion by utilizing a photovoltaic effect generated by the PN junction.
Next, a method for manufacturing the photovoltaic power generation apparatus 100 will be described. The manufacturing method comprises the following steps: preparing a back plate 1, and preparing a thin film solar cell panel 3 on the back plate 1; arranging a first reflecting member 5a on the thin-film solar cell panel 3; arranging a second reflecting member 5b at the periphery of the thin-film solar cell panel 3; covering a packaging adhesive film 4 on the thin-film solar cell panel 3; covering a transparent front plate 2 on the packaging adhesive film 4; and laminating the back plate 1, the thin-film solar cell panel 3, the first reflecting member 5a, the second reflecting member 5b, the packaging adhesive film 4 and the transparent front plate 2 to obtain the photovoltaic power generation device 100.
In summary, the photovoltaic power generation apparatus 100 and the manufacturing method thereof solve the problem of low photoelectric conversion efficiency of the photovoltaic power generation apparatus 100, and ensure that the photovoltaic power generation apparatus 100 can generate power by using the light energy irradiated into the non-power generation region, thereby improving the photoelectric conversion efficiency thereof.
