Chinese PV Industry Brief: Hoshine plans 200,000 ton poly fab
Hoshine will invest $2.75 billion in the new polysilicon factory. Elsewhere, Irico New Energy today announced a strategic co-operation agreement with PV manufacturer Jinko Solar that will see it prioritize supply of solar panel glass.
TOPCon vs PERC – a battle between fast learning curves
TOPCon solar modules will gain more market share if their average efficiency, already higher than that of PERC panels, continues to improve, according to Stefan Glunz, PV research chief at Germany’s Fraunhofer Institute for Solar Energy Systems ISE. In an upcoming pv magazine webinar on the potential of TOPCon tech, Glunz will show how to reduce costs and increase efficiency.
Solar cell based on silver bismuth sulfide nanocrystals achieves 9.17% efficiency
Scientists in Spain have fabricated a silver bismuth sulfide (AgBiS2) material with an absorption coefficient that is claimed to be 5-10 times greater than any other material currently used for PV technology. A cell built with these nanocrystals showed a power conversion efficiency of 9.17%, an open-circuit voltage of 0.495V, a short-circuit current of 26.75mA/cm2, and a fill factor of 63%.
New PV module recycling tech from France
French start-up Rosi Solar has developed an industrial solution claimed to be capable of recovering high purity silicon, silver and copper contained in end-of-life PV modules. The company’s technology is based on a pyrolysis process that makes it possible to isolate the different metals from the cells.
