Defect engineering is applied to hybrid (CH3NH3)PbI3 organic–inorganic perovskites. These materials have become one of the most promising low‐cost alternatives to traditional semiconductors in the field of photovoltaics and light emitting devices. Here Helium ion irradiation at low energy has been used as a tool for the controlled introduction of point defects in both single crystals and polycrystalline thin films. The irradiation defects modify the opto‐electronic properties as probed using…

Energy Tuning of Electronic Spin Coherent Evolution in Methylammonium Lead Iodide Perovskites.
It is shown that this coherent evolution can be tuned by choosing the pump-probe energy within the lowest optical-absorption band, and it is explained as the result of two main contributions: the localized electron and the localized hole.

Strong covalency-induced recombination centers in perovskite solar cell material CH3NH3PbI3.
The results show that, in order to prevent the deep-level defects from being effective recombination centers, the equilibrium carrier concentrations should be controlled so that the Fermi energy is about 0.3 eV away from the band edges.
Materials processing routes to trap-free halide perovskites.
It is shown that films grown under iodine-rich conditions are prone to a high density of deep electronic traps (recombination centers), while the use of a chloride precursor avoids the formation of key defects responsible for short diffusion lengths and poor photovoltaic performance.

Narrow Linewidth Excitonic Emission in Organic-Inorganic Lead Iodide Perovskite Single Crystals.
A strong thermal broadening of the free excitonic emission is highlighted, due to exciton-LO-phonon coupling, which turned to be very short-lived with a subnanosecond dynamics, mainly induced by the fast trapping of the excitons.
Defect-induced local variation of crystal phase transition temperature in metal-halide perovskites
It is proposed that upon cooling from 160 to 140 K, domains of the crystal containing fewer defects stay in the tetragonal phase longer than highly defected domains that readily transform to the high bandgap orthorhombic phase at higher temperatures.
