Efficiency of Silicon Solar Cells Climbs

IEEE Spectrum Recent Content

Efficiency of Silicon Solar Cells ClimbsIn research published this week in Nature Energy, researchers at Kaneka Corp., a resin and plastics manufacturer based in Osaka, describe the first silicon solar cell to achieve a record-breaking 26.3 percent efficiency—a 0.7 percent increase over the previous record. That may not seem like a lot, but it’s really a big step when you consider that silicon solar cells’ theoretical maximum efficiency is just 29 percent.
