Scientists break Shockley-Queisser efficiency limit for silicon solar cell in experiment
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 at temperatures of 30-50 Kelvin, which are a few tens of degrees above absolute zero.
Scientists boost organic solar cell efficiency using polymer zwitterions
A research team based in China and the United States has developed electroactive polymer zwitterions to modify zinc oxide interlayers in organic solar cells. Their work was found to passivate defects in organic solar cells, helping to improve device performance and stability.
