A method of manufacturing a solar cell includes the following steps. An ion implantation process is performed to a first surface of a substrate to form a first doping layer. Then, the ion implantation process is performed to a second surface of the substrate to form a second doping layer. After that, an annealing process is performed to the structure formed by the substrate, the first doping layer and the second doping layer, and forming a first passivation layer on the first doping layer and a second passivation layer on the second doping layer by the annealing process. A third passivation layer is formed on the first passivation layer formed after the annealing process and a fourth passivation layer is formed on the second passivation layer formed after the annealing process. Afterward, conductive electrodes are formed on the third passivation layer and the fourth passivation layer, respectively.

Method of manufacturing solar cell

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

One-step diffusion method for fabricating a differential doped solar cell

A method of fabricating a differential doped solar cell is described. The method includes the following steps. First, a substrate is provided. A doping process is conducted thereon to form a doped layer. A heavy doping portion of the doped layer is partially or fully removed. Subsequently, an anti-reflection coating layer is formed thereon. A metal conducting paste is printed on the anti-reflection coating layer and is fired to form the metal electrodes for the solar cell.
