Abstract
Amorphous silicon (a-Si) alloy solar cells are attractive for space applications for several reasons, including potential for very low mass. Ultralight a-Si alloy solar modules have been fabricated and modifications to achieve dramatic increases in specific power (W/kg) identified. For modules on stainless steel and Kapton, specific powers of 384 W/kg and 1256 W/kg have been achieved. For 0.5 mil Kapton with thinner bus bars, an extremely high specific power > 2000 W/kg is possible for a module with 10% AM0 efficiency.
