Abstract In perovskite solar cells (PSCs), defective grain boundaries (GBs) and/or surface due to photo‐excitation and the resulted suboptimal carrier dynamics at perovskite/charge transport layer, have largely limited further performance enhancement aggravated PSCs instability. Fundamentally preventing formation of these trap‐states through a simple efficient approach is thus critical both device stability. Herein, novel semiconductive silicon naphthalocyanine derivative (Cl‐SiNcTI) reduce...
Abstract High‐quality perovskite films are essential for achieving high performance of optoelectronic devices; However, solution‐processed known to suffer from compositional and structural inhomogeneity due lack systematic control over the kinetics during formation. Here, microscopic homogeneity is successfully enhanced by modulating conversion reaction using a catalyst‐like system generated foaming agent. The chemical evolution this catalytic revealed multimodal synchrotron toolkit with...
A perovskite solar cell with DDQ doped spiro-OMeTAD HTL delivers a champion power conversion efficiency of 21.16%.
Abstract High‐quality and low‐defect perovskite active layer (PVK) electron transport (ETL) are essential for high‐performance solar cells (PSCs). Herein, an alkylamine salt, cyclohexylmethylammonium chloride (CMACl) is introduced into tin oxide (SnO 2 ) ETL. CMACl, possessing protonated −NH 3 + group Cl − ions, not only effectively inhibits the aggregation of SnO colloids enhances quality ETLs, but also reduces passivates defects on ETLs. On other hand, via across‐interface effect salt by...
