Solar cells account for approximately six percent of the electricity used on Earth; however, in space, they play a significantly larger role, with nearly all satellites relying on advanced solar cells for their power. That’s why Georgia Tech researchers will soon send 18 photovoltaic cells to the International Space Station for a study of how space conditions affect the devices’ operation over time.

“The main goal here is to improve power generation in space,” said Jud Ready, principal research engineer at the Georgia Tech Research Institute (GTRI) and Associate Director of External Engagement with Georgia Tech’s Institute for Matter and Systems. “The limiting factor on the performance of a spacecraft is usually how much power you can produce. Power, size, weight, complexity, cost – all of these are tied closely to the electrical generation of the solar panels.”
