| Popis: | Thermal curing of the styrene-functionalized 9,9-diarylfluorene-based triaryldiamine monomer (VB-DAAF) forms an ideal p-type organic electrode interlayer capable of resisting solvation of the polar precursor solution in fabricating methylammonium lead iodide (CH3NH3PbI3) perovskite/fullerene (C60) planar heterojunction hybrid solar cells. The polymerized VB-DAAF film exhibits a good energy level alignment with the valence-band-edge level of the CH3NH3PbI3 perovskite to facilitate the transport of holes. The large energy barrier to the conduction-band-edge level of the CH3NH3PbI3 perovskite effectively blocks electrons from reaching the positive electrode and reduces the photon energy loss due to recombination. The best-performing cell with the configuration of glass/indium–tin oxide/polymerized VB-DAAF/CH3NH3PbI3 perovskite/C60/bathocuproine/aluminum is free of a poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) layer to achieve an open-circuit voltage (VOC) = 1.02 V, a short-circuit cur... |
