Abstract

The invention belongs to the field of photovoltaic new energy technology, and specifically discloses a photovoltaic reflecting light reflection film. The photovoltaic reflecting light reflection filmcomprises a thin film base, wherein a UV resin transition layer is arranged on the upper surface of the thin film base; UV solidification triangular lugs capable of being deviated left and right on the longitudinally horizontal plane according to design requirements are transversely and continuously distributed on the upper surface of the UV resin transition layer; a metal light reflection reflecting layer is arranged on the top of each UV solidification triangular lug; and a reflecting light reflection surface is formed on the upper surface of each metal light reflection reflecting layer; andthe compensation problem of an existing solar power generation light source is changed in the aspects of light source compensation and light source maximization, so that the illumination intensity and area of a solar power generation battery piece are increased, the conversion efficiency loss caused by the restriction of an external light source is reduced, a single light source can be amplifiedand reflected into a plurality of light sources, the light sources are dispersed to the surface of the battery piece in 180 degrees in a unique mode, and powerful light source compensation is formed so as to obtain higher conversion efficiency.

Description

technical field [0001] The invention relates to the technical field of photovoltaic new energy, in particular to a refractive reflective film for photovoltaics. Background technique [0002] Solar cell is a very promising new power source, which has three advantages of permanence, cleanliness and flexibility. Solar cells have a long service life. As long as the sun exists, solar cells can be used for a long time with one investment; compared with thermal power generation and nuclear power generation, solar cells will not cause environmental pollution; A medium-sized power station of 10,000 kilowatts is so small that it can only be used by one household, which is unmatched by other power sources. [0003] Cells, the core of photovoltaic modules, have become the focus of the entire photovoltaic industry. The power generation of existing cells is limited by light sources (cloudy, night and light transmittance), conversion loss (loss during power transmission) and surface area ...
