An apparatus is provided for highly accelerated life testing (HALT) of multi-junction solar cells according to a method that utilizes a high vacuum chamber, as well as lenses and windows transparent to broad spectrum solar radiation from typically a single source to house packaged solar chips and temperature monitoring and control means during testing, thereby allowing substantially greater control of environmental variables such as temperature, atmospheric composition, and light spectrum than is currently available.
