1. Formamidinium lead trihalide: a broadly tunable perovskite for efficient planar heterojunction solar cellsEnergy & Environmental Science · 2014 · 4,167 citations

   Perovskite-based solar cells have attracted significant recent interest, with power conversion efficiencies in excess of 15% already superceding a number of established thin-film solar cell technologies. Most work has focused on a methylammonium lead trihalide perovskites, with a bandgaps of…

2. High Charge Carrier Mobilities and Lifetimes in Organolead Trihalide PerovskitesAdvanced Materials · 2013 · 3,247 citations

   Organolead trihalide perovskites are shown to exhibit the best of both worlds: charge-carrier mobilities around 10 cm2 V−1 s−1 and low bi-molecular charge-recombination constants. The ratio of the two is found to defy the Langevin limit of kinetic charge capture…

3. A mixed-cation lead mixed-halide perovskite absorber for tandem solar cellsScience · 2016 · 3,073 citations

   Metal halide perovskite photovoltaic cells could potentially boost the efficiency of commercial silicon photovoltaic modules from ∼20 toward 30% when used in tandem architectures. An optimum perovskite cell optical band gap of ~1.75 electron volts (eV) can be achieved by…
