Pyridination of hole transporting material in perovskite solar cells questions the long-term stability

Mohammad Khaja Nazeeruddin, Natalia Gasilova, Sanghyun Paek, Kasparas Rakstys

In this work, for the first time, reactive radical-cation species present in hole-transporting materials were shown to react with tert-butylpyridine additive, routinely used in hole transporting layer composition. As a result, new pyridinated products were ...
