Low Cost and Lightweight Amorphous Silicon Alloy Solar Array for Space Application 1999-01-2553

The constellation of satellites to be launched in the next few years to provide rapid global access to information needs low-cost and lightweight solar arrays. Multijunction thin-film amorphous silicon (a-Si) alloy solar cells deposited on lightweight and flexible substrates are ideal to meet this challenge. a-Si alloy is radiation hard, and has superior high temperature performance. We present results on fabrication of a-Si alloy solar cells on 0.5-mil-thick stainless steel using a low-cost production technology to achieve high efficiency under AM0 condition and their space qualification.
