TL;DR: Procedures for testing organic solar cell devices and modules with respect to stability and operational lifetime are described and generally agreed test conditions and practices are generally agreed to allow ready comparison between laboratories and to help improving the reliability of reported values.

TL;DR: The present findings suggest that replacing the methylammonium component in CH3 NH3 PbI3 to a species without acid protons could improve tolerance to oxygen and enhance stability.

TL;DR: Tin-based perovskites turned out to be most promising in terms of power conversion efficiency; however, also the toxicity of these tin-based Perovskite compounds is argued.

TL;DR: In this paper, the authors showed that modifying the chemical composition of the germanium perovskite, i.e., introducing bromide ions into the methylammonium Germanium iodide perovsite, leads to a significant improvement of the solar cell performance along with a slight enhancement of the stability of the device, achieving power conversion efficiencies up to 057% in MAGeI27Br03 based solar cells with a planar p-i-n architecture using PEDOT:PSS as hole and PC70BM as electron

TL;DR: In this article, a large number of flexible polymer solar modules comprising 16 serially connected individual cells was prepared at the experimental workshop at Riso DTU and the functional devices were subjected to an inter-laboratory study involving the performance and the stability of modules over time in the dark, under light soaking and outdoor conditions.
