METHOD FOR MANUFACTURING A SOLAR CELL WITH A TWO-STAGE DOPING |
摘要 |
A method for manufacturing a solar cell via a two-stage doping includes the steps of forming an oxide layer, which can be penetrated by a first dopant, on at least one part of the surface of a solar cell substrate, forming an opening in the oxide layer in at least one high-doping region by removing the oxide layer in this high-doping region and diffusing the first dopant into the at least one high-doping region of the solar cell substrate through the opening. The first dopant is diffused into the solar cell substrate through the oxide layer. The diffusing-in through the openings and through the oxide layer takes place at the same time in a common diffusion step and the solar cell substrate is diffused in the common diffusion step in an at least partially hydrophilic state.
