CsInAgCl: A new lead-free halide double perovskite with direct band gap
George Volonakis, Amir A. Haghighirad, Rebecca L. Milot +7
ABBX halide double perovskites based on bismuth and silver have recently been proposed as potential environmentally-friendly alternatives to lead-based hybrid hali…
Perovskite-perovskite tandem photovoltaics with optimized bandgaps
Giles E. Eperon, Tomas Leijtens, Kevin A. Bush +24
We demonstrate four and two-terminal perovskite-perovskite tandem solar cells with ideally matched bandgaps. We develop an infrared absorbing 1.2eV bandgap perovskite, $FA_{0.75}Cs…
Lead-Free Halide Double Perovskites via Heterovalent Substitution of Noble Metals
George Volonakis, Marina R. Filip, Amir Abbas Haghighirad +4
Lead-based halide perovskites are emerging as the most promising class of materials for next generation optoelectronics. However, despite the enormous success of lead-halide perovs…
