Abstract

The present invention provides a method for manufacturing a solar battery, comprising the steps of: doping rubber on a first surface of a semiconductor substrate to form a selective emitter; endowing an unrough surface to the selective emitter via a shield doped with the rubber; and endowing an unrough surface to a second surface of the semiconductor substrate by utilizing a rough barrier layer.

Description

technical field [0001] The present invention relates to a method for making a solar cell, especially a method for forming a selective emitter with a non-roughened surface on the front side (first surface) of a semiconductor substrate by using doping glue, and using a roughened barrier layer to make A method for manufacturing a solar cell with a non-roughened surface on the back side (second surface) of a semiconductor substrate. Background technique [0002] Due to the limited oil resources on earth, the demand for alternative energy has been increasing in recent years. Among various alternative energy sources, solar energy has become the green energy with the most development potential because of its endless supply through the cycle of nature. [0003] Due to problems such as high production cost, complex manufacturing process and poor photoelectric conversion efficiency, the development of solar energy still needs further breakthroughs. Therefore, how to manufacture sola...
