Spectrolab has set a new solar cell efficiency world record for a non-concentrated solar cell of 38.8% and in doing so has beaten the company’s own previous record of 37.8%, set in April.
Best known for supplying multi-junction solar cells and panels for concentrated photovoltaic (CPV) applications, satellites and spacecraft, Spectrolab developed the new cell from Boeing semiconductor bonding technology.
According to the company, this new multi-junction high efficiency cell could be used on high power spacecraft and unmanned aerial vehicles. The record 38.8% conversion efficiency has been verified by the US Department of Energy via its National Renewable Energy Laboratory in Colorado, which also verified the previous Spectrolab record earlier this year.
Research analysts Lux Research predicted in June 2012 that by 2022, Spectrolab cells could reach 50% efficiency.
Spectrolab is a subsidiary of Boeing and part of Boeing Defense, Space and Security.
