Abstract

The invention relates to a method for manufacturing a solar cell. The method comprises the following steps of: performing ion implantation on a first surface of a substrate to form a first doped layer; performing ion implantation on a second surface of the substrate to form a second doped layer; performing an annealing process on a structure formed by the substrate, the first doped layer and the second doped layer; forming a first passivation layer on the first doped layer and forming a second passivation layer on the second doped layer through the annealing process; forming a third passivation layer on the first passivation layer which is formed through the annealing process; forming a fourth passivation layer on the second passivation layer which is formed through the annealing process; and forming conductive electrodes on the third passivation layer and the fourth passivation layer respectively.

Description

technical field [0001] The present invention relates to a method for manufacturing a photoelectric device, and in particular to a method for manufacturing a solar cell. Background technique [0002] The doping method of traditional solar cells is to use a diffusion process to dope dopants into the substrate to form a p-n junction. This p-n junction generates electron-hole pairs when receiving light, and then generates a current in the substrate to achieve purpose of photoelectric conversion. For example, if the solar cell uses a p-type substrate, during the diffusion process of the solar cell, the p-type substrate is placed in a high-temperature furnace tube to perform an n-type phosphorus diffusion process to dope the p-type substrate with n-type dopants. [0003] However, in the high-temperature phosphorus diffusion process, unnecessary phosphorous-silicate glass (Phospho-Silicate Glass, PSG) will be formed, and after the diffusion process, the entire p-type substrate wil...
