Synthesis of ZnO-based nanostructures for heterostructure photovoltaic cells

A model describing heterostructure solar cells based on zinc and copper oxides is developed. Seed layers of ZnO and CuO are synthesized by spray pyrolysis. To form a bulk heterojunction, ZnO nanorods are grown by hydrothermal synthesis. The morphological, electricaland optical properties of the fabricated structures are investigated.
