Method for improving and stabilizing solar power generation efficiency

Abstract

The invention relates to a solar power generation technology, in particular to a method for improving and stabilizing solar power generation efficiency, which comprises a solar power generation panel, glass, a crystalline silicon photocell, a lower EVA (Ethylene Vinyl Acetate) adhesive film, a back film and a metal fixing frame, and is characterized in that the lower surface of the glass is plated with a reflecting film from bottom to top; an antireflection film is plated on the upper surface of the glass from top to bottom and is used for reducing the light loss of input light and improving the power generation efficiency of the crystalline silicon photocell; spatial isolation is formed between the glass and the crystalline silicon photocell, and cold air is introduced into the isolated space through the air cooler, so that the temperature of the crystalline silicon photocell is controlled to be 25 DEG C, and the power generation efficiency of the crystalline silicon photocell is stabilized. The device can be widely used in engineering design, so that the solar power generation efficiency is not influenced by temperature, and the power generation efficiency is not reduced.

Description

technical field [0001] The invention relates to a solar power generation efficiency technology, in particular to a method for improving and stabilizing the solar power generation efficiency. Background technique [0002] Existing solar panel structures such as figure 1 As shown, the glass, the upper EVA film, the crystalline silicon photovoltaic cell, the lower EVA film, the back film, the metal fixed frame, the glass, the upper EVA film, the crystalline silicon photovoltaic cell, the lower EVA film, and the back film are connected in sequence, and the sun passes through From the glass and the EVA film to the light-receiving surface of the crystalline silicon photovoltaic cell, especially in the hot weather, the temperature of the crystalline silicon photovoltaic cell will rise rapidly. This leads to a decrease in the photoelectric efficiency of crystalline silicon photovoltaic cells. [0003] In solar power generation, the high temperature will affect the solar module, wh...

Problems solved by technology

[0006] Theoretically and practically speaking, the above scheme can realize the purpose of the inventor, but the actual process is complicated, the cost is increased, and it is difficult to promote it in a large area

[0007] Another problem to be involved in the present invention is: when the crystalline silicon photovoltaic cell absorbs sunlight, it also loses part of the light energy utilization due to the light reflection on the surface, and the light reflection loss is also related to the incident angle.
