- Аннотация: Herein, we introduce a series of new (X–DADAD)n-type conjugated polymers comprised of benzo[1,2-b:4,5-b′]dithiophene (X), benzo[c] [1,2,5]thiadiazole (acceptor, A), and thiophene (donor, D) units as highly promisinghole transport materials for perovskite solar cells (PSCs). The rational engineering of the backbone structure andthe side chains enabled high power conversion efficiencies of up to 20% in n-i-p perovskite solar cells in combinationwith impressive operational stability: the devices preserved initial performance after>2500 h of continuousillumination at open-circuit conditions. The origins of the observed long-term perovskite solar cells stabilityenabled by the newly designed polymeric hole transport materials have been revealed through the use of infraredscattering-type scanning near-field optical microscopy and further elucidated by density functional theory calculations.The presented findings point to novel strategies of designing advanced charge transport materials to simultaneouslyendow the PSCs with high performance and durability.
