In PIN-type perovskite solar cells (PSCs), the hydroscopicity and acidity of poly(3,4-ethylenedioxythiophene)-poly(styrene-sulfonate) (PEDOT:PSS) hole transport layer (HTL) have critical influences on device stability. To eliminate these problems, Nafion, hydrophobic perfluorosulfonic copolymer, is incorporated into PEDOT:PSS by a simple spin-coating process. For modified film, Nafion/PSSH (poly(styrene sulfonate) acid) acts as an electron-blocking surface PEDOT-rich domain tends to gather...
