摘要：

We have developed high efficiency large area a-Si: H and a-SiGe: H multi-junction solar cells using a Modified Very High Frequency (MVHF) glow discharge process. We conducted a comparative study for different cell structures, and compared the initial and stable performance and light-induced degradation of solar cells made using MVHF and RF techniques. Besides high efficiency, the MVHF cells also demonstrate superior light stability, showing <10% degradation after 1000 hour of one-sun light soaking at 50 degrees C. We also studied light-induced defect level and hydrogen evolution characteristics of MVHF deposited a-SiGe: H films and compared them with the RF deposited films.
