摘要
Recently, organic-inorganic halide perovskites with the composition ABX_3[A = CH_3NH_3~+(MA), NH = CHNH_3~+(FA) or Cs~+; B = Pb or Sn; X = Cl, Br, I] have received increasing research attention as light absorbers in solid-state thin-film solar cells..The state-of-the-art high-performing PSC devices routinely incorporated hole-transporting materials(HTMs) as p-type contacts, which play a key role in extraction and collection of the photo-generated holes from the perovskites, and thus minimizing undesired recombination losses at the interfaces.~1 Herein, we successfully applied a facile in-situ solid-state synthesis of conducting polymer poly(3,4-ethylenedioxythiophene)(PEDOT) as a HTM, directly on top of the perovskite layer, in conventional mesoscopic perovskite solar cells(PSCs)(n-i-p structure).The fabrication of the PEDOT film only involved a very simple in-situ solid-state polymerisation step from a monomer 2,5-dibromo-3,4-ethylenedioxythiophene(DBEDOT) made from a commercially available and cheap starting material.The excellent power conversion efficiency(PCE) is 17.0% measured at 100 mW cm~(-2) illumination(AM 1.5G).The present finding highlights the potential application of PEDOT made from solid-state polymerisation as a HTM for cost-effective and highly efficient PSCs.~2
