First Solar is poised to release the first bifacial solar panel tapping advanced thin-film semiconductor tech. They’re calling it the Series 6 Plus Bifacial PV module and is built off of their Series 6 monofacial module platform. It has a transparent back contact, allowing for bifacial energy gain and infrared wavelengths of light to pass through rather than be absorbed as heat. Expectations are that it will lower the operational temp of the bifacial module for higher yield.
