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.
