Enhancement of the Performance of Perovskite Solar Cells, LEDs, and Optical Amplifiers by Anti-Solvent Additive Deposition
(Wiley, 2017-02-17)
The efficiency of perovskite optoelectronic devices is increased by a novel method; its suitability for perovskite solar cells, light-emitting diodes, and optical amplifiers is demonstrated. The method is based on the ...
Surface Polarization Model for the Dynamic Hysteresis of Perovskite Solar Cells
(American Chemical Society, 2017-02)
The dynamic hysteresis of perovskite solar cells consists of the occurrence of significant deviations of the current density–voltage curve shapes depending on the specific conditions of measurement such as starting voltage, ...
Formation Criteria of High Efficiency Perovskite Solar Cells in Ambient Conditions
(Royal Society of Chemistry, 2017)
The field of lead halide perovskites for solar cell applications has recently reported impressive power conversion (PCE) above 22 % using complex mixed cation formulations. Very importantly, highest PCE have been obtained ...
Changes from Bulk to Surface Recombination Mechanisms between Pristine and Cycled Perovskite Solar Cells
(American Chemical Society, 2017)
Several aspects on the photophysical characterization of lead halide hybrid organic–inorganic perovskite solar cells remain unsolved. It has been observed that ionic transport and polarization of the interfaces cause very ...
