New Solar Cell Efficiency Record Achieved For 9 Millimeter-Squared Cell Made Of Gallium Arsenide

A new conversion efficiency record for 9 millimeter-squared solar cells made of gallium arsenide was recently achieved by engineering researchers at the University of Arkansas. The new record — 14% efficiency — was achieved via the utilization of a new approach using a thin layer of zinc oxide. With the new … [continued]
