Bifunctional Surface Engineering on SnO2 Reduces Energy Loss in Perovskite Solar Cells
Published in ACS Energy Letters 2020, 5 (9), 2796–2801, 2020
NH4F surface treatment on SnO2 simultaneously reduces surface defects and induces chemical doping of the substrate, improving energetic alignment and achieving 23.2% PCE in perovskite solar cells.
