Abstract

The invention relates to an L-section type concentrating photovoltaic battery chip, and belongs to the technical field of solar photovoltaic power generation. The L-section type concentrating photovoltaic battery chip comprise a negative electrode section layer, a concentrating photovoltaic battery base material layer, a positive electrode layer and an active area; one surface of the concentrating photovoltaic battery base material layer is coated with the negative electrode section layer while the other surface is coated with the positive electrode layer; and the part except the negative electrode section layer is the active area. By adoption of the battery chip, the usage amount of the concentrating photovoltaic battery base material can be greatly reduced, so that the manufacturing cost of the concentrating photovoltaic battery chip can be lowered; along with the increasing of concentrating times of a lens, the electrode section width can be improved; meanwhile, by adjusting an electrode into the electrode section, the unchanged property of the light-receiving area is maintained, and the overall power generation efficiency of the concentrating photovoltaic system is not reduced; and by improving the width of the negative electrode section, it is ensured that after the amplifying times of the lens is improved, the concentrating light can be converted into high-current electric energy which can be smoothly conducted through the negative electrode section.

Description

technical field

[0001] The invention relates to a photovoltaic power generation component, in particular to an L-segment concentrating photovoltaic cell chip, which belongs to the technical field of solar photovoltaic power generation. Background technique

[0002] Generally, the main benefit sought by concentrated photovoltaic power generation systems is to obtain high-density sunlight concentrated from Fresnel lenses on the effective area of ​​concentrated photovoltaic cell chips. The higher the multiple of the lens, the higher the density of sunlight obtained, the fewer concentrated photovoltaic cell chips used on the same area, and the lower the power generation cost per unit area.

[0003] At present, the focal spot gathered from the Fresnel lens is usually square, and the shape and size of the focal spot are usually consistent with the shape and size of the concentrated photovoltaic cell chip, so that the focal spot gathered by the Fresnel lens can be completely conve...
