“…This notable broadening hints at enhanced charge transfer within these moieties, a phenomenon familiar in BODIPY systems. [37][38][39] The UV-Vis spectra of the thin films on quartz glass substrates (Figure 1b) reveal a noteworthy trend: while the overall absorption profile closely resembles that observed in solution, the films exhibit a pronounced red shift and broadening of the ICT band. This change is ascribed to enhanced electron delocalization and more robust intramolecular interactions in the solid state.…”

Perovskite solar cells (PSCs) have become a research hotspot since their dramatic increase in power conversion efficiency (PCE), surpassing 25 % due to advances in cell engineering and interfacial layers. Within the last factor, hole transporting materials play a crucial role in enhancing device performance and stability. Among several molecular building blocks, BODIPYs are attractive for the design of novel HTMs due to their outstanding photophysical and charge transport properties easily tuned by synthetic modifications. Here we report the synthesis of five new BODIPY‐based HTMs PyBDP 1–5, functionalized at the meso‐ and α‐ positions with pyrenyl and arylamino units, respectively. The resulting compounds exhibit broad absorption in the visible region, remarkable thermal stability, narrow bandgaps, suitable energy levels and good hole extraction capability, as subtracted from experimental and computational characterizations. The performance of the BODIPY derivatives as HTMs is evaluated in planar inverted (p‐i‐n) PSCs and compared to commonly used HTM PTAA, resulting in highly efficient systems, reaching PCEs very close to that obtained with the reference polymer (21.51 %). The incorporation of these BODIPY‐based HTMs result in an outstanding PCE of 20.37 % for devices including PyBDP‐1 and 19.97 % for devises containing PyBDP‐3, thus demonstrating that BODIPY derivatives are a promising alternative to obtain simple and efficient organic dopant‐free HTMs.This article is protected by copyright.
