Solar cell structure and solar cell manufacturing method

Abstract

The invention relates to a solar cell structure which can enhance the current transmission efficiency of a solar cell and a solar cell manufacturing method. In the technical scheme of the solar cell structure, a substrate and a transparent substrate are laminated to be opposite to each other; two electronic transmission layers are respectively on the adjacent surfaces of the inner sides of the substrate and the transparent substrate, are separated from each other and are laminated to be opposite to each other; a light absorbing reaction layer comprises a light absorbing reaction part and a first wire, an antipodal layer comprises an antipodal part and a second wire, and grooves are respectively formed and are cut through the light absorbing reaction part, the antipodal and the two electronic transmission layers, so that the current generated by the light absorbing reaction part and the antipodal part can respectively penetrate through the adhered electronic transmission layers to a nearest wire, thereby reducing the resistance loss and achieving the optimal current transfer effect.

Description

technical field [0001] The invention relates to a solar cell and a solar cell manufacturing method, in particular to a solar cell structure and a solar cell manufacturing method used to increase the current transmission efficiency of the solar cell. Background technique [0002] The dye solar cell, which uses dyes to sensitize light to generate current, is a brand-new solar cell developed recently. The dye molecules absorb light to generate a potential difference, and then generate current; although the current photoelectric conversion efficiency is not as good as that of silicon solar cells, but The cost is very low, and if its photoelectric conversion efficiency is gradually improved, it will most likely become the mainstream technology of solar cells in the future. [0003] The substrate of the dye solar cell is usually a glass substrate, with two upper and lower layers respectively, and the substrate can also be a transparent and bendable polymer foil (polymer foil); the...

Problems solved by technology

This method has achieved the purpose of guiding the current and solved the problem of electron flow or current conduction everywhere. However, this method is not the most effective method. The illustration shows that the current in the area A4 encircled by the dotted line is obviously going to the left The square wire 11 is relatively close, but it is forced to travel to the far right wire 11. In this way, the current is consumed due to the too long transmission distance and the resistance value
