The US Department of Energy’s National Renewable Energy Laboratory (NREL) has confirmed Longi’s achievement of a world record-breaking efficiency rating of 33.9% for a perovskite-silicon tandem solar cell.
The new series comes in seven versions, with power outputs between 560 W and 590 W. The power conversion efficiency ranges between 21.7% and 22.8%.
SEG Solar says it will invest $60 million in a new U.S. factory. It currently produces panels at factories in Vietnam and Indonesia.
Longi Solar said it will invest approximately $6.6 billion in 100 GW of wafer capacity and 50 GW of solar cell capacity in Shaanxi province, China.
The solar manufacturing supply chain is among the Chinese industries hit by a combination of soaring power demand, coal shortages for power generation, and carbon emission reduction measures.
The achievement was confirmed by the Institute for Solar Energy Research and is claimed as a world record for a p-type TOPCon cells.
Preliminary results for a handful of companies suggest that commodity price rises are having an impact on earnings.
Solar module producer Longi announced its second price increase in less than a month, and industry sources expect wafer prices to continue rising in June.
JA Solar has agreed to sell three solar farms to China Power Investment Corporation, while Tongwei announced lower prices on a number of cells. Eight leading players are calling for the standardization of PV products with 210 mm wafers.
