Perovskite-silicon tandem solar cells have the potential to overcome the theoretical efficiency limit of conventional silicon solar cells but require effective light management and well-adjusted interlayer properties in the complex stack. “Özde Seyma Kabakli’s work tackles this issue, presenting an optimization study on serial co-sputtered indium-zinc oxide (IZO) films used as front TCO layer for perovskite-silicon tandem solar cells,” says Prof. Stefan Glunz, division director of Photovoltaics Research at Fraunhofer ISE. “We cheer for Özde’s research and are happy that her results received this appreciation at the conference.”
