Abstract :
Cuprous oxide (Cu2O)-based solar cells with fullerene (C60) were fabricated on indium tin oxide (ITO) by a spin-coating method. The microstructure and cell performance of the solar cells with the Cu2O:C60 structure was investigated. A photovoltaic device based on an ITO/Cu2O:C60 bulk heterojunction structure fabricated by the spin-coating method provided short-circuit current density of 0.11 mA cm−2 and open-circuit voltage of 0.17 V under an Air Mass 1.5 illumination. The microstructures of the Cu2O active layer were examined by using X-ray diffraction and transmission electron microscopy. The energy levels of the present solar cells are also discussed.
