TL;DR: In this article, a perovskite solar cell was fabricated by using room-temperature deposition processes and the cells were based on a layer of methylammonium lead iodide perovsite that is prepared by sublimation in a high-vacuum chamber and sandwiched between two thin organic charge-transport layers.

TL;DR: This work reports the preparation of 6 nm-sized nanoparticles of this type by a simple and fast method based on the use of an ammonium bromide with a medium-sized chain that keeps the nanoparticles dispersed in a wide range of organic solvents.

TL;DR: Flexible perovskite based solar cells with power conversion efficiencies of 7% have been prepared on PET based conductive substrates as discussed by the authors, demonstrating their suitability for roll to roll processing.

TL;DR: The reciprocity relation between electroluminescence and photovoltaic quantum efficiency is evaluated and it is concluded that the emission from the perovskite devices is dominated by a sharp band-to-band transition that has a radiative efficiency much higher than that of an average OPV device.

TL;DR: Semitransparent perovskite solar cells with a high power conversion efficiency (PCE) above 6% and 30% full device transparency have been achieved by implementing a thin perov-skite layer and a simple foil compatible layout as discussed by the authors.
