TLDR
Recommendations are made on how accelerated testing should be performed to rapidly develop solar cells that are both extraordinarily efficient and stable.Abstract:
This review article examines the current state of understanding in how metal halide perovskite solar cells can degrade when exposed to moisture, oxygen, heat, light, mechanical stress, and reverse bias. It also highlights strategies for improving stability, such as tuning the composition of the perovskite, introducing hydrophobic coatings, replacing metal electrodes with carbon or transparent conducting oxides, and packaging. The article concludes with recommendations on how accelerated testing should be performed to rapidly develop solar cells that are both extraordinarily efficient and stable.read more

TL;DR: A method for incorporating chloride is reported that allows for fabrication of stable triple-halide perovskites with a band gap of 1.67 electron volts and a factor of 2 increase in photocarrier lifetime and charge-carrier mobility that resulted from enhancing the solubility of chlorine by replacing some of the iodine with bromine to shrink the lattice parameter.
