Popis:	Abstract 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 (WF) and reduce hole selectivity. A straightforward and workable solution is presented in this study, which partially restores the WF of V2Ox as deposited on silicon and improving solar cell efficiency, avoiding the use of amorphous silicon.
