Description
Technical Field
The utility model relates to a thin-film solar cell technical field specifically is a photovoltaic apron glass for copper indium gallium selenide battery.
Background
In recent years, due to the acceleration of urbanization process in China, building energy consumption is increased year by year, so that the large-scale application of renewable energy sources in the building field is accelerated, and the method is one of key measures for reducing building energy consumption and adjusting building energy consumption structures. The building integrated technology (BIPV) of the solar energy system organically combines the solar energy system products into the building field, so that the solar energy system has the building function, and simultaneously, the energy generated on the surface of the building is utilized to realize the double effects of providing clean energy and reducing the energy consumption of the building.
The Copper Indium Gallium Selenide (CIGS) thin-film solar cell has the characteristics of good weak light (scattering) effect, low temperature coefficient, no attenuation for a long time and the like, so that the power generation performance is good, and the power generation is stable. Meanwhile, the solar energy source has the advantages of simple production process, no pollution and the like, and is evaluated as the future of solar energy sources by the industry. The advantages of CIGS solar cells are therefore very well suited to the implementation of "building integrated photovoltaics" applications.
The CIGS cell is generally prepared by coating a cell functional layer on a glass substrate in the form of a multilayer film, laminating the film with an EVA film and a photovoltaic cover glass layer, and putting the film into application in the form of an assembly, wherein the color of the CIGS cell is black due to the fact that the cell functional layer is black, and the EVA film and the photovoltaic cover glass are colorless and transparent. The application of the conventional solar cell to buildings is fundamentally restricted because the buildings as the environment and urban landscape have very high requirements on the appearance color, and the single black color of CIGS cannot meet the requirements of building design.
At present, a plurality of organizations and manufacturers at home and abroad research that solar cells with single color are made into color cell components, and have small-batch production and application, but all have various problems. At present, there are two main methods for obtaining a color CIGS solar cell: one is to color the CIGS cell assembly by coloring the photovoltaic cover glass; and secondly, coloring the CIGS cell component by coloring the EVA film. Both of the above methods are chemical color generation, which is the result of color generation by pigments (nonferrous metal or metal compound ions, dyes, etc.) in photovoltaic cover glass and films, and selective absorption of light. Therefore, the light transmittance is greatly reduced (only 40% -50%) without exception, which directly causes the conversion efficiency of the solar cell to be sharply reduced by more than 20%. This leaves the CIGS cell a dilemma for application in BIPV: either at the expense of the aesthetic color of the building or the power generation efficiency of the CIGS cell.
