PHOTOVOLTAIC MATERIALS WITH CONTROLLABLE ZINC AND SODIUM CONTENT AND METHOD OF MAKING THEREOF

摘要

A solar cell includes a substrate, a first electrode located over the substrate, a sodium doped p-type copper indium selenide (CIS) based alloy semiconductor absorber layer located over the first electrode, a zinc and sodium doped n-type copper indium selenide (CIS) based alloy semiconductor layer located on the p-type semiconductor absorber layer, and a second electrode located over the n-type semiconductor layer.
