Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] A 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 .

[0016] Concentrating solar cell substrate layer 2 skillfully combines the positive electrode layer 3 and multiple 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 the electrode layers and connecting wires can withstand the rated current of l0~50 amperes.

[0017] The negative electrode segment layer 1 is processed 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, the length...

Abstract

The invention relates to a large-current concentrating solar cell chip and belongs to the technical field of solar power generation. The large-current concentrating solar cell chip comprises multiple negative electrode section layers, a concentrating solar battery base material layer and a positive electrode layer, wherein the concentrating solar battery base material layer enables the positive electrode layer and the negative electrode section layers to be combined ingeniously through a special process. According to the large-current concentrating solar cell chip, on the regional conditions of over 1000 times of condensation and strong light rays, it can be guaranteed that a large current smoothly passes through the positive electrode layer and the negative electrode section layers to be led out without damaging the cell chip; meanwhile, the shape and design of the I-shaped negative electrode section layers of the cell chip effectively enlarge the relative light receiving area, and therefore the purpose of improving the conversion efficiency of the cell chip is achieved.

Description

technical field [0001] The invention relates to a photovoltaic power generation component, in particular to a high-current 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 collected from Fresnel lenses on the effective area of ​​concentrating solar cells. The higher the density, the fewer concentrating solar cells used on the same area, and the lower the power generation cost per unit area. [0003] As the lens multiplier increases, the intensity of light concentrated on the concentrating solar cell is greater, and the current converted from the concentrating solar cell is greater. At present, all concentrating solar cells are based on the light intensity of 1000W / m 2 Tested and mass-produced at room temperature, the width of the negative electrode is ...
