Abstract
A solar cell includes a substrate containing a first impurity of a first conductivity type and made of a crystalline semiconductor, an emitter region positioned on the substrate and containing a second impurity of a second conductivity type different from the first conductivity type, the emitter region being made of a non-crystalline semiconductor, a surface field region positioned on the substrate and containing a third impurity of the first conductivity type, the surface field region being made of non-crystalline semiconductor, a first electrode connected to the emitter region, and a second electrode connected to the surface field region, wherein at least one of the emitter region and the surface field region is made of amorphous metal silicide containing a metal material.
