Problems solved by technology

At present, all concentrated photovoltaic 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 within 0.5mm, so its rated current is relatively small, and it is easy to fuse the negative electrode under the conditions of large concentration multiples and strong light intensity.
At the same time, when welding or binding processing

Example Embodiment

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

[0015] A kind of concentrated photovoltaic cell, such as Figure 1~2 As shown, the substrate layer 2 of the concentrating photovoltaic cell has a positive electrode layer 3 on one side, and a negative electrode segment layer 1 on the other side.

[0016] Concentrating photovoltaic cell substrate layer 2 cleverly 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 It can also ensure that the electrode layers and connecting wires can withstand the rated current of 10 to 50 amperes.

[0017] The negative electrode segment layer 1 is processed on the substrate layer 2 of the concentrating photovoltaic cell. The width of the negative electrode segment layer 1 is 0.5 to 1.5 mm, the length i...

Abstract

The invention relates to a high-current concentrating photovoltaic battery chip and belongs to the technical field of solar electric power generation. The high-current concentrating photovoltaic battery chip comprises a plurality of negative electrode section layers, a concentrating photovoltaic battery substrate layer and a positive electrode layer, wherein the concentrating photovoltaic battery substrate layer is used for combining the positive electrode layer and a plurality of negative electrode section layers together through a special process in a smart way. The battery chip provided by the invention can guarantee that high current can be smoothly led out by the positive electrode layer and the negative electrode section layers without damaging battery chip when condensation multiple is higher than 1000 and the light intensity is very high; and meanwhile, the shape and design of the I-shaped negative electrode section layers of the battery chip can effectively increas the relative light-receiving area, thereby reaching the purpose of improving the conversion efficiency of the battery chip.

Description

technical field [0001] The invention relates to a photovoltaic power generation component, in particular to a high-current concentrating photovoltaic battery sheet, which belongs to the technical field of solar power generation. Background technique [0002] Generally, the main benefit sought by high-power concentrated photovoltaic photoelectric conversion receivers is to obtain high-density solar radiation concentrated from Fresnel lenses on the effective area of ​​concentrated photovoltaic cells. The higher the multiple of the lens, the higher the density of solar radiation, and the fewer concentrated photovoltaic cells used on the same area, the lower the power generation cost per unit area. [0003] As the lens magnification increases, the intensity of light concentrated on the concentrated photovoltaic cells increases, and the current converted from the concentrated photovoltaic cells increases. At present, all concentrated photovoltaic cells are based on the light...
