The energy density of the newly developed lithium-sulfur prototype far exceeds the one of common lithium -ion batteries.
China’s Longi Green Energy has set a new world record for crystalline silicon solar module efficiency with its independently developed hybrid passivated back contact (HPBC) 2.0 module, achieving a conversion efficiency of 25.4%, according to a certification report from Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE).
The Chinese PV manufacturer said its new module series has a power conversion efficiency of up to 24.8% and temperature coefficient is -0.26% per C.
China’s Huawei has built a 400 MW/1.3 GWh solar-plus-storage off-grid facility in Red Sea New City, Saudi Arabia.
In a paper published in nature, the Chinese module maker explained that the 33.9%-efficient tandem device it unveiled in December 2023 is based on a bilayer intertwined passivation strategy that combines efficient electron extraction with further suppression of nonradiative recombination. It also revealed that its two-terminal tandem prototype devices achieved an efficiency of 34.6%.
The China-based solar manufacturer and Oman’s renewable investment entity Bakarat Investment have agreed to jointly establish a 10 GW solar module factory in the country with an investment of around $200 million.
China Three Gorges has announced plans to build a 16 GW renewables cluster in China’s Inner Mongolia region, including 8 GW of solar, 4 GW of wind, a 200 MW solar thermal system, a 4 GW coal plant, and a 500 MWh energy storage system.
Chinese solar cell maker Hainan Drinda New Energy Technology plans to build a 10 GW factory in Oman to produce tunnel oxide passivated contact (TOPCon) solar cells.
The Chinese manufacturer said its new Hi-MO X6 Artist series has an efficiency of up to 22.3% and a power output ranging from 420 W to 430 W. The smaller version is currently priced at CNY 298 ($41.7)/m2 and the largest model is sold at CNY 268/m2.
The European Solar Test Installation (ESTI) has confirmed Longi’s achievement of a world record-breaking efficiency rating of 34.6% for a perovskite-silicon tandem solar cell.
