| Abstract [eng] |
The performance of perovskite solar cells (PSCs) is partially dependent on the properties of the hole transporting material (HTM) used. Here, we present the synthesis and study of novel benzothiazole-based arylamine HTMs. The compounds are thermally stable, decomposing at temperatures >350 °C, and exist in amorphous states. The ionization potential values of the HTMs are between 5.26-5.62 eV, which are optimal with respect to the valence band energy of perovskite (∼5.7 eV). PSCs employing the best performing HTM resulted in a power conversion efficiency (PCE) of 20.74% with a fill factor (FF) of 77.6%. With this we present donor-π-bridge-acceptor type-strategy as an effective method to increase charge transport properties of benzothiazole-based small molecule HTMs that are obtained in high yield via a simple Knoevenagel condensation reaction resulting in improved performance of the hole transporting layer in PSCs. |
