Scientists report experimental breach of Shockley-Queisser efficiency limit for silicon solar cell

A Chinese-US research group claims to have achieved a power conversion efficiency of over 50% in an n-type single-junction solar cell by inhibiting light conversion to heat at extremely low temperatures. The result was achieved temperatures of 30-50 Kelvin, which are a few tens of degrees above absolute zero.Researchers from the University of Delaware in the United States and Taizhou University in China claim to have achieved a record power conversion efficiency of "50%-60%" in a silicon solar cell by inhibiting the lattice atoms' thermal oscillations at extremely low temperatures. "For our experiment, ...
