MIS or SIS Solar cells

摘要

The function of the insulating film in MIS and SIS solar cells can also be fulfilled by a semiconductor with a sufficiently large energy gap. The doping of the quasi insulating layer guarantees good fill factors and short-circuit current densities also at a relatively high film thickness. For cadmium selenide solar cells with a quasi insulating film made of zinc selenide, copper is preferably used as a doping material.
