Numerical investigation of copper oxide-based heterojunction solar cells

Abstract

wxAMPS (analysis of microelectronic and photonic structures) software numerical modeling was applied to explore the effects of metal oxide semiconductors on the photovoltaic (PV) properties of solar cells. For different n-type semiconductors (TiO 2 , ZnO, SnO 2 , Ga 2 O 3 , and n-Si), the influences of the thickness of the CuO layer on the PV properties of heterojunction cells were explored. Moreover, the temperature stability of the cells was modeled. Furthermore, a band gap gradient structure (including CuO, Cu 4 O 3 and Cu 2 O) cell demonstrated an enhancement of their PV performance. This research can provide a theoretical basis for the materials of oxide as PV cells.
