Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings.
[0016] A high-efficiency concentrated solar cell, such as Figure 1~2 As shown, one side of the substrate layer 2 of the concentrator solar cell is the positive electrode layer 3 , and the other side is the negative electrode segment layer 1 .
[0017] Concentrating solar cell substrate layer 2 cleverly combines the positive electrode layer 3 and the two negative electrode segment layers 1 through a special process, which can ensure that large currents are smoothly guided through the positive electrode layer 3 and the negative electrode segment layer 1 At the same time, it can also ensure that each electrode layer and connecting wire can withstand a rated current of more than 10 amperes.
[0018] Process the negative electrode segment layer 1 on the base material layer 2 of the concentrating solar cell, the width of the negative electrode segment layer 1 is 0.5~1.5mm...

Abstract
The invention relates to an efficient concentration solar cell, and belongs to the technical field of solar power generation. The efficient concentration solar cell comprises two rows of negative electrode section layers, a concentration solar cell base material layer and a positive electrode layer. The concentration solar cell base material layer enables the positive electrode layer and the two rows of I-shaped negative electrode section layers to be ingeniously combined together through a special technology. According to the efficient concentration solar cell, a photovoltaic system enables four or more concentration solar cells to be tightly arrayed together directly, namely, the four or more concentration solar cells are welded at a time to form a concentration solar photovoltaic conversion receiver; meanwhile, the concentration solar photovoltaic conversion receiver which is formed by the four or more concentration solar cells can be radiated by a radiator, working strength is greatly reduced, working time is greatly shortened, and thus working efficiency can be improved; in addition, due to the shape and the design of the negative electrode section layers of the solar cell, the light absorption area is effectively increased, and the conversion efficiency of the concentration solar cell can be overall improved.
Description
technical field [0001] The invention relates to a photovoltaic power generation component, in particular to a high-efficiency concentrating solar cell, which belongs to the technical field of solar power generation. Background technique [0002] Generally, the main benefit sought by high-magnification concentrating solar photoelectric conversion receivers is to obtain high-density solar radiation concentrated from Fresnel lenses on the active area of concentrating solar cells. The higher the magnification of the lens, the higher the density of solar radiation, the fewer concentrating solar cells used on the same area, and the lower the power generation cost per unit area. [0003] As the magnification of the lens increases, the light energy converging on the concentrating solar cell increases, a small part of the light energy is converted into electrical energy, and most of the light energy is converted into heat energy. At present, all concentrating solar energy systems ...
