Summary: | Abstract In this work, heterojunction, solar cells based on inorganic semiconductors were fabricated at various thermal-annealing temperatures using vapor deposition techniques. The active layer primarily consists of a bilayer comprising a hole transporting copper oxide-CuO and an electron transporting zinc oxide-ZnO nanoparticles. It was observed that the power conversion efficiency-PCE increased from 0.06 to 0.08% with an increase in annealing temperature from 400 to 500 °C, possibly, as a result of increased absorption, in the visible region with increasing temperature. A significant increase in the crystallinity of single and bilayer films was also observed with increasing annealing temperature. |
