Abstract

p-CuSCN was sensitized by n-Cu₂O quantum dots (QDs) to fabricate a new solid state photovoltaic cell. QDs of n-Cu₂O were deposited by boiling Cu/p-CuSCN photoelectrodes in a 1M CuSO4 solution to form Cu₂O QDs on p-CuSCN. Boiling periods controlled the n-Cu₂O quantum dot size. Activated coconut shell charcoal (CAC) was introduced on top of the Cu₂O as the upper electrode and finally ITO glass was placed on CAC to fabricate the device.

Keywords
