Surpassing 90% Shockley-Queisser VOC Limit in 1.79 eV Wide-Bandgap Perovskite Solar Cells Using Bromine-Substituted Self-Assembled Monolayers

All-perovskite tandem solar cells (TSCs) hold the promise of surpassing the efficiency limits of single-junction solar cells. However, enhancing TSC efficiency faces the challenge of significant open-circuit voltage (VOC) loss...
