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 at temperatures of 30-50 Kelvin, which are a few tens of degrees above absolute zero.
Mexico launches tender for 300 MW solar plant
Mexican state-owned utility Comisión Federal de Electricidad (CFE) is seeking proposals for the Puerto Peñasco Secuencia III solar plant, which will also include 103 MW of battery capacity.
EU policies could cut cost gap between European and Chinese solar modules
A report by SolarPower Europe and Fraunhofer ISE finds EU-made solar modules cost €0.103 ($0.12)/W more than Chinese imports, but targeted policies could close the gap and help reach the EU’s 30 GW annual manufacturing target by 2030.
REC leads US residential solar panels as Tesla loses storage share
REC led the US residential solar panel market in the first half of 2025, while Tesla lost share in home batteries and inverters amid supply and policy pressures, according to EnergySage.
