Enhanced Hole Extraction of WOx/V2Ox Dopant‐Free Contact for p‐type Silicon Solar Cell

Advanced Materials Interfaces, 2022
Nonstoichiometric vanadium oxide V2Ox has been demonstrated to serve as a hole‐selective contact in crystalline silicon solar cells. A reaction between V2Ox deposited by thermal evaporation and silicon can, however, result in a decreased work function ...
