摘要:
A one-step diffusion method for fabricating a differential doped solar cell is described. The one-step diffusion method includes the following step. First, a substrate is provided. A doping control layer is formed on the substrate. The doping control layer includes a plurality of openings therein. A doping process is conducted on the substrate to form heavy doping regions under the openings of the doping control layer and light doping regions on the other portion of the substrate
