TL;DR: In this article, a bottom-up cost model for perovskite PV modules fabricated using feasible low-cost materials and processes is presented, which shows that PSCs can emerge as a cost leader in PV power generation if critical remaining issues can be resolved.

TL;DR: In this article, laser beam induced current imaging is used to investigate the spatial and temporal evolution of the quantum efficiency of perovskite solar cells under controlled humidity conditions and several interesting mechanistic aspects are revealed as the degradation proceeds along a four-stage process.

TL;DR: In this article, the authors review major advances in perovskite solar cells that have contributed to the recent efficiency enhancements, including the evolution of device architecture, the development of material deposition processes, and the advanced device engineering techniques aiming to improve control over morphology, crystallinity, composition, and interface properties of the perovsite thin films.

TL;DR: In this paper, the structural and optical properties of the materials formed when a range of compositions of methylammonium iodide and lead iodide were reacted at temperatures from 40 to 190 °C.

TL;DR: This work examines the changes in the photoexcited carrier dynamics for methylammonium lead iodide and bromide films exposed to nitrogen gas containing water vapor at 80% relative humidity to elucidate the degradation mechanisms of perovskite films in high humidity from the perspective of the photophysics.
