1. Efficient Hybrid Solar Cells Based on Meso-Superstructured Organometal Halide PerovskitesScience · 2012 · 10,717 citations

   The energy costs associated with separating tightly bound excitons (photoinduced electron-hole pairs) and extracting free charges from highly disordered low-mobility networks represent fundamental losses for many low-cost photovoltaic technologies. We report a low-cost, solution-processable solar cell, based on a highly…

2. Electron-Hole Diffusion Lengths Exceeding 1 Micrometer in an Organometal Trihalide Perovskite AbsorberScience · 2013 · 10,444 citations

   Organic-inorganic perovskites have shown promise as high-performance absorbers in solar cells, first as a coating on a mesoporous metal oxide scaffold and more recently as a solid layer in planar heterojunction architectures. Here, we report transient absorption and photoluminescence-quenching measurements…

3. 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…

4. 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…

5. 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…

6. Perovskites: The Emergence of a New Era for Low-Cost, High-Efficiency Solar CellsThe Journal of Physical Chemistry Letters · 2013 · 3,051 citations

   Over the last 12 months, we have witnessed an unexpected breakthrough and rapid evolution in the field of emerging photovoltaics, with the realization of highly efficient solid-state hybrid solar cells based on organometal trihalide perovskite absorbers. In this Perspective, the…
