Abstract

Strong adhesion between hole transporter layer and transparent conductive oxide is crucial for efficient charge transport and interface stability of inverted perovskite solar cells (PSCs). This study demonstrates a significant improvement in interface adhesion achieved through rational hole transporter design. We design Poly-DCPA, a novel polymeric hole transporter exhibiting over four-fold enhancement in adhesion compared to the self-assembled monolayer (SAM) counterpart called DCPA. Poly-DCPA also shows superior conductivity and improved uniformity, enabling blade-coated PSCs fabricated in ambient conditions to achieve a remarkable power conversion efficiency of 24.9%. This surpasses the performance of PSCs using DCPA SAM as the hole-transporting layer. Furthermore, Poly-DCPA-based PSCs exhibit excellent stability, retaining 94% of the initial PCE after over 900 hours of light soaking at 85oC. This work presents a promising strategy for designing hole transporters with enhanced interface adhesion, paving the way for highly efficient and stable PSCs.
