Popis: Highlights A versatile material-antimony potassium tartrate is added to wide-bandgap perovskite cells for the first time. Inverted wide-bandgap perovskite solar cells with a structure of ITO/MeO-2PACz/perovskite/C60/ALD-SnO2/Cu yield a champion power conversion efficiency of 20.35%. A perovskite/perovskite four-terminal tandem solar cell with efficiency of 26.3% is achieved.
