Symmetrical Structure High Heat Dissipation Photovoltaic Module

Abstract

The invention discloses a high heat dissipation photovoltaic module of a symmetrical structure. The high heat dissipation photovoltaic module is characterized by comprising a front plate polymer material layer, a cell and a back plate polymer material layer which are stacked sequentially from top to bottom, wherein the front plate polymer material layer comprises a surface protecting layer, a high transmitting plastic base layer doped with quantum dots and a packaging material layer which are stacked sequentially from top to bottom, and the back plate polymer material layer comprises a surface protecting layer, a high transmitting plastic base layer doped with quantum dots and a packaging material layer which are stacked sequentially from top to bottom and are symmetrical to the surface protecting layer, the high transmitting plastic base layer doped with quantum dots and the packaging material layer of the front plate polymer material layer. The photovoltaic module is of the symmetrical structure and can be used for a solar cell with two surfaces receiving light, light transmitting and photon absorption are promoted by means of a front plate and a rear plate, the photovoltaic conversion efficiency is increased, and the overhigh working temperature of the cell can be avoided by reducing the number of heat sources.

Description

technical field [0001] The invention belongs to the technical field of photovoltaics, in particular to a high heat dissipation solar cell module with a symmetrical structure Background technique [0002] At present, the solar monocrystalline or polycrystalline modules on the market all adopt the following structure, that is, the tempered glass layer, EVA layer, battery sheet, EVA layer, TPT layer and aluminum alloy frame are stacked sequentially from top to bottom. The front glass and packaging materials of such a structure pay more attention to the light transmittance, which is generally required to be above 91%, so as to absorb as many photons as possible, so that the cell has higher conversion efficiency and power output. The back film is mostly made of fluorine-containing polymer composite materials, which play protective functions such as water blocking and insulation, but it also brings about the problem of difficult heat dissipation. [0003] American scientists have...

Problems solved by technology

However, double-sided light-receiving solar cells also have application disadvantages. Under the same irradiation conditions, the output power of each side is slightly lower than that of conventional single-sided solar cells. The best angle to receive sunlight

[0004] At present, the main research direction is to improve the above problems through the research of double-sided solar cells, and further improve the power generation efficiency of double-sided solar cells. However, there are few reports focusing on the improvement of the front and rear plate packaging materials of double-sided solar cells. The present invention consists of Here comes
