Description

A colored solar cell module

technical field

The utility model relates to the field of solar battery power generation, in particular to a colored solar battery assembly.

Background technique

As a clean and renewable energy source, solar energy is widely used. Building integrated photovoltaics is an important application field of photovoltaic power generation in the world and an important development direction of photovoltaic applications. BIPV requires solar cells to meet the aesthetic requirements of building integration, but the colors of existing solar cells are relatively single, mainly including brown (amorphous silicon solar cells), blue (crystalline silicon solar cells), etc., which cannot Provides a variety of optional colors, and the appearance decoration effect is general. At present, there is a method of adding a color film in the middle to change the color of the solar cell, but the effect is not obvious, especially for the amorphous silicon thin film solar cell, the effect of changing the color is not ideal.

Utility model content

The purpose of the utility model is to solve the defect of single color existing in the prior art, and provide a color solar battery module with simple structure, multiple color choices, and perfect integration with building colors.

The technical solution for realizing the purpose of this utility model is a colored solar cell assembly, including a transparent substrate packaged as one, a composite transparent dielectric film, a transparent protective layer, a solar cell unit, packaging materials and a backplane protective layer; the transparent dielectric film and the transparent protective layer are sequentially arranged on one side of the transparent substrate; the solar battery unit, the packaging material and the backsheet protective layer are sequentially arranged on the other side of the transparent substrate.

The composite transparent dielectric film is an optical cut-off film.

Adopting the above-mentioned technical scheme, the utility model has the following beneficial effects: the utility model sets a non-absorbing composite optical medium film and a non-light-absorbing transparent protective layer in sequence on one side of the transparent substrate, and the composite optical medium film is an optical cut-off film, The cut-off wavelength shows the color of the finished product, so it can selectively reflect light. At the same time, on the other side of the transparent substrate, a solar cell layer, an encapsulation material layer, and a backplane protective layer are arranged in sequence, and then packaged into a solar cell module. Viewed from the incident direction, the solar cell modules can present different colors, which makes the solar cells rich in diversification, so as to meet the color requirements of solar cell building integration, and is very suitable for curtain walls and roofs of buildings, etc. occasion.
