Solar Energy News Buffet

As noted in an article yesterday, I’ve been very busy in the past month (well, months…) moving into a new home and following the birth of a sweet little cleantech lover. Inevitably, “roundup articles” of important or interesting cleantech news we didn’t cover dropped off as a result. With a big backlog … [continued]

Black Silicon Solar Cell Hits 18.2% Efficiency, Should Help to Reduce Costs

Black-silicon solar cells with 18.2% efficiency have been created by researchers from the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL). These don’t need extra anti-reflection layers (like typical solar cells do), which should help to significantly lower the cost of solar energy. The specially designed nanostructured surface ensures … [continued]
