Title: High band gap II-VI and III-V tunneling junctions for silicon multijunction solar cells

Abstract

This patent describes a multijunction silicon solar cell comprising p/n junction solar cells epitaxially grown in layers to receive solar energy in series through the n-type layer of each solar cell. The p-type layer of one is connected to the n-type layer of the next in series by a p+/n+ tunnel junction of III-V or II-VI semiconductor material of higher band-gap than silicon, and has a near perfect lattice match with silicon.
