Spectrolab making 30.7% efficient solar cells for space applications

Boeing subsidiary Spectrolab Inc of Sylmar, CA, USA, which manufactures multi-junction solar cells and panels for concentrated photovoltaic and spacecraft power systems, says that it has begun manufacturing a higher-efficiency space solar cell, providing opportunities for the aerospace industry to develop lighter and less expensive spacecraft.

Due to Spectrolab’s advances in manufacturing, the new XTJ Prime cell has achieved a solar energy conversion efficiency of 30.7% (higher than any other comparable model currently available, it is claimed). First delivery of the higher-efficiency XTJ Prime cells is expected later this year
