Graphic abstract: New small-molecular benzimidazole derivatives for photovoltaics: Synthesis, optical and electrochemical properties and application in perovskite solar cells

Abstract: New small molecule photovoltaic materials containing benzimidazole fragment were prepared by cross-coupling of the corresponding 1-bromo-4-(imidazol-2-yl)benzenes with multiborylated/stannylated polycyclic (het)arenes. Energies of HOMO/LUMO levels were calculated from cyclic voltammetry and UV/VIS spectroscopy data and are within the ranges –5.27... –5.73 and –2.33...–2.89 eV, respectively. Solar cells based on three different perovskites as light absorbing layers and compound SM7 as electron transporting material demonstrated power conversion efficiency values up to 10.78% without doping additives or perovskite engineering.

Keywords: benzimidazole derivatives, cross-coupling, small molecules, perovskite, solar cells, electron transfer materials, power conversion efficiency.
