Problems solved by technology

[0003] Cells, which are 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 (front conductive wires) The shading part) affects its power generation efficiency by only 20%, and the experimental data in the laboratory can only reach a conversion efficiency of 25%. How to maximize the use of light sources, reduce the power loss in the conversion process, and reduce the shading part of the cell surface to improve power generation conversion Efficiency will be the key to the development of solar power generation in the later stage

Abstract

The invention belongs to the technical field of novel photovoltaic energy, and relates to a key component used in a solar cell assembly, in particular to a bijection type reflecting solder strip. The bijection type reflecting solder strip comprises a film substrate, wherein a film sticking layer is fixed on the bottom surface of the film substrate; the top surface of the film substrate is provided with a plurality of projections which are connected integrally with the film substrate and are formed uniformly; each projection has a regular rectangular pyramid structure; a metal layer is jointed to the upper surface of the film substrate. By adopting the reflecting solder strip, light sources are utilized to the maximum extent; meanwhile, power loss in a conversion process is reduced, the surface shading portion of a solar cell is reduced, and the power generation conversion efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic new energy, and relates to a key component used in a solar cell assembly, in particular to a through-beam reflective welding ribbon. Background technique [0002] Solar cells are 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, as small as a solar battery pack for one household, is unmatched by other power sources. [0003] Cells, the core of photovoltaic modules, have been 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 (l...
