Dark I-V Characteristics and Carrier Transport Mechanism in Nano-Crystalline Silicon Thin Film/Crystalline Silicon Hetero-Junction Solar Cells
纳米硅/晶体硅异质结电池的暗I-V特性和输运机制

N nc-Si/c-Si heterojunction solar cells were prepared with the hot-wire chemical vapor deposition technique.The dark I-V characteristics of the cells with different atomic hydrogen treatments on the c-Si surface were measured.At room temperature,the I-V curves were fitted by a two-diode model in which four different voltage regions were recognized:the shunt resistance(V<0.15),nonideal diode(0.150.5V)regions.The modeled results show that the ideality f...
