Forty-two days in the SPA, building a stability parameter analyzer to probe degradation mechanisms in perovskite photovoltaic devices

Abstract

The ISOS protocols provide a robust framework for stability testing and facilitating the description and comparison of results within the community. However, they are not prescriptive on how to achieve the conditions required for degradation. Herein, we discuss various options for satisfying the ISOS light stability series (ISOS-L-#) of tests, a homebuilt testing apparatus that is readily adaptable for decoupling and monitoring stressors in reliability tests, and a homebuilt software suite that is capable of extracting figures of merit over time, cleaning up the data, filtering between data sets, and visualizing the data in several ways. With these, we provide a case study to illustrate the type of data the system produces and an approach to extract degradation mechanisms and/or acceleration factors with such a tool.
