Design Of Heterojunction Photocell For Optimize Performance Using Numerical Simulation

In our paper work simulation study and analysis of nZnO/p-Si heterojunction photo detector are reported. In this project work we can use a program in AFROS-HET (Automat for simulation of hetero-structures) simulator and study of important quality parameters, their impacts and variation. AFROS-HET consists of one dimensional numerical program for model of multi layer homo or heterojunction solar cells We concluded that photodetector responsivity increases with thickness of zno and decreases when donor and acceptor doping concentrations increases. Results of simulation have very good quantum efficiency and different impacts and variation.
