Abstract

In this work, we report a low-cost, industrially viable chemical oxidation process (named as NCPRE-oxide process) using sodium hypochlorite (NaOCl) solution applicable to 5-inch pseudo-square monocrystalline silicon Al-BSF solar cells. Introduction of this new ultrathin oxide layer in between silicon nitride layer and silicon shows the improvement in the open circuit voltage and thereby the efficiency of solar cells.
