Tracing the Dynamic Chemical Transformations of Spiro‐OMeTAD in Operating Perovskite Solar Cells
ABSTRACT A significant stability challenge for perovskite solar cells (PSCs) lies in the widely used LiTFSI‐doped Spiro‐OMeTAD (Spiro) hole transport layer (HTL), in n‐i‐p configured cells. In this study, we used the sputtering depth profile X‐ray photoelectron spectroscopy (SDP‐XPS) to systematical...
