Abstract

A method for making a solar cell from crystalline silicon, and a solar cell made from crystalline silicon produced according to the method. Neighboring pxnx junctions are electrically insulated by simultaneously introducing a p- and an n-conductive dopant layer. The interleaved contact fingers of the solar cell are electrically insulated with respect to one another by providing contiguous regions with different dopings.
