摘要：

The effective utilization of self-assembled monolayers (SAMs) has indeed resulted in significant improvement in the power conversion efficiency (PCE) of inverted perovskite solar cells (PSCs). However, the poor interface contact between self-assembled monolayer (SAM) and perovskite layers limits the further improvement of inverted PSCs. Herein, polyaniline is employed as a conductive adhesive, enabling interaction with the perovskite and simultaneous coupling with the SAM, to optimize the buried interface contact. Furthermore, the adhesive strategy is validated to alleviate residual tensile strain at the buried interface using the non-destructive back grazing-incidence wide-angle X-ray scattering (BGIWAXS) technique. As a result, the optimized inverted PSCs achieve a champion PCE of 25.59% with impressive stability by retaining 97.3% of its initial efficiency after 1200h under ambient conditions and light-emitting diode illumination. The findings provide a facial adhesive bridging strategy to play more impressive functions in the SAM-based inverted PSCs.
