Modeling of a solar cell based on Co$_3$O$_4$ and (Co$_3$O$_4$)$_{1-x}$(ZnO)$_x$ films

Numerical simulation of a solar cell based on the heterojunction of nanocrystalline films of zinc oxide modified with cobalt oxide (Co$_3$O$_4$)$_{1-x}$(ZnO)$_x$ and cobalt oxide (Co$_3$O$_4$) formed by solid-phase pyrolysis is carried out. The effect of the electron affinity of (Co$_3$O$_4$)$_{1-x}$(ZnO)$_x$ films, the thickness of the Co$_3$O$_4$ layer and the concentration of acceptors in it on the photoelectric parameters has been studied.
