ABSTRACT:
A process for effectively producing an inexpensive solar cell by using a metallic substrate and growing a polycrystal semiconductor layer of a large crystal grain size. And a process for effectively producing a high quality and inexpensive solar cell by forming a polycrystal semiconductor layer of a large crystal grain size and with a reduced defect level density in grain boundaries on a polycrystal semiconductor layer of a small crystal grain size which serves as a crystal seed.
