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.
Qcells’ customs-detained cells released to its Georgia factories
A tightening in federal customs enforcement under a law to restrict imports made by forced labor in China’s Xinjiang region had snagged Qcells cell imports from Southeast Asia.
The steel supply crunch threatening U.S. solar ambitions
With U.S. domestic steel mills booked solid through 2025, a sudden doubling of tariffs on imported steel has created a critical bottleneck for American industries. The move, which hits specialized Indian steel particularly hard, is now delaying projects for builders and renewable energy developers who rely on steady, affordable supply.
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.
