Hosted by: CSIC Research Scientist Mónica Lira Cantu, Nanostructured Materials for Photovoltaic Energy Group Leader at ICN2

Abstract:The talk will review consensus procedures for planning, conducting, and reporting stability testing of perovskite solar cells (PSC) recently formulated by a broad perovskite research community [1]. In particular, the suggested protocols highlight the importance of testing for: (1) Redistribution of charged species upon application of electric fields [2]; (2) distinguishing between degradation induced by various stress factors, (3) reversible degradation with qualitatively different recovery dynamics [3,4]. The recommended protocols are not meant to replace existing qualification standards (i.g., IEC 61730 and IEC 61215), but rather to contribute to developing an understanding of PSC degradation mechanisms. Acceptance of these protocols and sharing the suggested datasets will facilitate inter-laboratory coordination and assist in the accumulation of PSC stability data acquired under well-defined and comparable conditions. This would allow the application of advanced approaches to analyzing large data sets, such as machine learning methods, and accelerate the development of stable PSC devices.
