Practical Enhancements in Current Density and Power Generation of Bifacial Semitransparent Ultrathin CIGSe Solar Cells via Utilization of Wide Bandgap Zn‐Based Buffer (Adv. Sci. 13/2022)

Semitransparent Ultrathin CIGSe Solar Cells In article number 2105436, Joo Hyung Park and co‐workers develop a bifacial and semitransparent ultrathin (STUT) Cu(In(1‐x),Ga(x))Se(2) (CIGSe) solar cell with a wide bandgap Zn(O,S) buffer, and establish the concept and method to compare power generation ability by defining bifacial compatible efficiency (BCE) to reflect the albedo effect advantage in bifacial application, comparing with monofacial power conversion efficiency (PCE).
