众所周知,用太阳能电池作宇宙飞行器的电源已获成功,但它在地球上的应用却受到极为严格的经济限制。因此对立足于掺杂无定形半导体的光生伏打器件抱有极大的兴趣,大量地制造这种器件要比制造单晶电池简便得多也低廉得多。RCA实验所(普林斯顿)的D·E·卡尔逊等报道说,用辉光放电无定形硅电池获得了高达5.5%的能量转换效率。他们以下述两种构型应用掺杂的 As we all know, the success of using solar cells as a power source for a spacecraft has been severely restricted by its economic application on Earth. Therefore, there is great interest in photovoltaic devices based on doped amorphous semiconductors, which are much simpler and less expensive to fabricate single crystal cells. RD Carlson at RCA Laboratories (Princeton) et al. Reported that up to 5.5% energy conversion efficiency was achieved with glow-discharge amorphous silicon cells. They apply doping in the following two configurations
