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: n-Cu2O, p-CuSCN, Quantum Dots
