What is the actual role of ZnO, ZnO/CdS and ZnO/metal/CdS layers in CdTe or CIGS solar cells?

23 November 2013 1 549 Report

Why?

They work as semi-conductors with n-type character intrinsically due to oxygen vacancies and zinc interstitials and are doped using different elements to work as p-type. Have large exciton binding energy that's why its suitable to be used in a solar cell
