ASU researcher innovates solar energy technology in space

gloved hand holding solar cellExperts predict that by 2050 we’re going to have global broadband internet satellite networks, in-orbit manufacturing, space tourism, asteroid mining and lunar and Mars bases. More than a gigawatt of solar energy will be needed to power these activities, or the equivalent of 3.125 million photovoltaic panels. However, because it is currently the most expensive component on a satellite, scientists are looking for ways to make solar energy in space affordable — and to keep solar power systems from degrading so quickly in the extremely harsh environment of space. Arizona State University postdoctoral researcher Stanislau “Stas” Herasimenka thinks he has the solution to provide cost-effective and efficient, next-generation solar power for space applications. Sustainability scientist Stuart Bowden, an associate research professor of electrical and energy engineering in the Ira A. Fulton Schools of Engineering, praised Herasimenka’s work both as a doctoral student and a postdoctoral scholar to create commercial-grade silicon heterojunction solar technology. “When I came to ASU in 2009, Stas was our first student to complete an experimental thesis, and his passion for solar was critical to kick-start the lab,” said Bowden, Herasimenka’s doctoral research adviser. “He did extensive theoretical modeling work but he was also the one who pushed on making his research commercial. Stas has really embraced the entrepreneurial spirit at ASU and it's great he has the support to take his lab work out into the world.” Read the full story on ASU Now.
