Unrestricted Travel in Solar Cells In the past 2 years, organolead halide perovskites have emerged as a promising class of light-harvesting media in experimental solar cells, but the physical basis for their efficiency has been unclear (see the Perspective by Hodes). Two studies now show, using a variety of time-resolved absorption and emission spectroscopic techniques, that these materials manifest relatively long diffusion paths for charge carriers energized by light absorption.

Extra long electron–hole diffusion lengths in CH3NH3PbI3−xClx perovskite single crystals
Long electron–hole diffusion lengths in organolead trihalide compounds play a key role in achieving the remarkable performance of perovskite photovoltaics. Diffusion lengths in solution-grown
The nature of free-carrier transport in organometal halide perovskites
TLDR
Nonadiabatic quantum molecular dynamics simulations elucidate the mechanisms underlying the excellent free-carrier transport in CH3NH3PbI3 and provide much needed structure-property relationships and time-resolved information that potentially lead to rational design of efficient solar cells.
Imaging the Long Transport Lengths of Photo-generated Carriers in Oriented Perovskite Films.
TLDR
By performing spatially scanned photocurrent imaging measurements with local illumination, it is directly shown that the perovskite films prepared here have very long transport lengths for photogenerated carriers, with a minority carrier (electron) diffusion length on the order of 10 μm.
Light-Induced Increase of Electron Diffusion Length in a p-n Junction Type CH3NH3PbBr3 Perovskite Solar Cell.
TLDR
Using cross-sectional electron-beam-induced current (EBIC) measurements, an increase in carrier diffusion length is found in MAPbBr3(Cl)-based solar cells upon low intensity blue laser illumination and the EBIC cross section profile indicates a p-n structure between the n-FTO/TiO2 and p-perovskite, rather than the p-i-n structures reported for the iodide derivative.
One-Dimensional Electron Transport Layers for Perovskite Solar Cells
TLDR
Despite the advantages of 1D ETLs, there are still challenges that need to be overcome to achieve even higher PCEs, such as better methods to eliminate or passivate surface traps, improved understanding of the hetero-interface and optimization of the morphology.
