Problems solved by technology

[0005] Obviously, the efficiency of existing solar cells is relatively low. Traditionally, in order to improve the efficiency of solar cells, the composition of materials is constantly modified. Although the efficiency has been improved, they are all limited by the sunlight band, making the efficiency of solar cells The improvement has encountered a bottleneck; therefore, there is a special need for a high-efficiency solar cell that can effectively improve the efficiency

Embodiment Construction

[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0020] Such as figure 2 As shown, a high-efficiency solar cell includes a solar cell panel 1 , and a phosphor layer 2 is arranged on the surface of the solar cell panel 1 .

[0021] The fluorescent material layer 2 is composed of uniformly distributed fluorescent powder, and the fluorescent material layer 2 is bonded to the solar cell panel 1 through an adhesive, and can also be painted, printed on the surface or in other ways.

[0022] Likewise, the phosphor layer 2 can also be disposed inside the surface of the solar cell panel 1 .

[0023] Such as figure 1 As shown, the maximum wavelength band of sunlight energy is 650nm-680nm, while the best conversion wavelength of solar cells is around 1000nm, which is determined by figure 1 It can be ...

Abstract

The invention discloses a high-efficiency solar cell. On the premise of the existing solar energy technology, the solar cell efficiency can be improved based on the original solar cell equipment without changing materials and production processes of the existing solar cells. The high-efficiency solar cell comprises a solar panel, and a fluorescent material layer is arranged on the surface of the solar panel. In the high-efficiency solar cell, the light wave band absorbed by the solar panel is changed by arranging the fluorescent material layer on the surface of the solar panel, thus effectively improving the efficiency of the solar cell and realizing the purpose of the invention.

Description

technical field [0001] The invention relates to a solar cell, in particular to a high-efficiency solar cell which can effectively improve the efficiency of the solar cell. Background technique [0002] Solar energy is an inexhaustible renewable energy source for human beings. It is also clean energy and does not produce any environmental pollution. Among the effective utilization of solar energy; solar photovoltaic utilization is the fastest growing and most dynamic research field in recent years, and it is one of the most watched projects. [0003] A solar cell is a device that responds to light and can convert light energy into electricity. There are many commonly used materials that can produce photovoltaic effects, such as: single crystal silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, indium selenium copper etc., their power generation principles are basically the same; taking crystal as an example, P-type crystalline silicon can be obtained by ...
