Despite the exciting recent research on perovskite based solar cells, the design space for further optimization and the practical limits of efficiency are not well known in the community. In this letter, we address these aspects through theoretical calculations and detailed numerical simulations. Here, we first provide the detailed balance limit efficiency in the presence of radiative and Auger recombination. Then, using coupled optical and carrier transport simulations, we identify the…

On the Uniqueness of Ideality Factor and Voltage Exponent of Perovskite-Based Solar Cells.
It is shown that perovskite-based solar cells have two universal features: an ideality factor close to two and a space-charge-limited current regime, and the mechanisms that lead to these universal features are identified through detailed numerical modeling.
Interface engineering of highly efficient perovskite solar cells
Perovskite films received a boost in photovoltaic efficiency through controlled formation of charge-generating films and improved current transfer to the electrodes and low-temperature processing steps allowed the use of materials that draw current out of the perovskites layer more efficiently.

These findings demonstrate that large hysteresis is not an inherent feature of planar heterojunctions, and that efficient charge extraction can be achieved with uniform halide perovskite materials with desired composition.
Photocarrier recombination dynamics in perovskite CH3NH3PbI3 for solar cell applications.
Using time-resolved photoluminescence and transient absorption measurements at room temperature, this work reports excitation-intensity-dependent photocarrier recombination processes in thin films made from the organo-metal halide perovskite semiconductor CH3NH3PbI3 for solar-cell applications, providing clear evidence that the free-carrier model is better than the exciton model for interpreting the optical properties of chiral semiconductors.
