Determination of the band structure diagram of semiconductor heterostructures applied in photovoltaics

Recently it has been found that the heterostructures of n-ZnO/p-Si are promising photovoltaic alternatives to silicon homojunctions. It is well known energy band diagram a heterostructure crucial for understanding its operation. This paper analyzes ZnO/p-Si by using free AMPS-1D computer program simulations. The obtained numerical results compared with theoretical calculations based on depletion region approximation model and Poisson’s equation electric potential. simulation also experimental C-V characteristics test heterostructure. simulated qualitatively consistent curve, which confirms correctness determined
