Robust Dipicolinic Acid-Anchored Self-Assembled Monolayers for High-Performance Wide-Bandgap and Tandem Perovskite Photovoltaics.
The anchoring group of self-assembled monolayer (SAM) hole-transporting materials dictates both substrate binding and interfacial passivation, serving as a key lever for high-performance perovskite photovoltaics. Herein, we report a novel SAM molecular material, denoted by XS21, engineered with a multidentate dipicolin...
