Popis: For silicon heterojunction solar cell with p-type a-Si:H back surface field, the effects of substrate resistivity on the performance of solar cell with different defect densities on the front and the rear surfaces of the p-type c-Si wafer are investigated numerically by computer simulation. The results indicate that the optimized resistivity of the substrate ( ρ op ) is related to the interface defect density on the front surface of c-Si wafer ( D it1 ), and ρ op increases with the increase of D it1 .The value scale of resistivity of substrate is influenced greatly by the interface defect density on the rear surface of c-Si wafer ( D it2 ) for ρ > ρ op , and the larger the value of D it2 , the smaller will the range of acceptable ρ value be.
