Synthesis, Characterization, and Photovoltaic Performance of Porphyrin-Fullerene Dyads

In this study, we describe the synthesis of porphyrin-fullerene dyads via a 1,3-dipolar cycloaddition, using a diphenylacetylene linker to bridge the porphyrin and [60]fullerene moieties. The target dyads were synthesized with good yields and exhibited significantly enhanced solubility in common organic solvents. Furthermore, representative porphyrin-fullerene dyads were applied as additives to perovskite solar cells, significantly enhancing their power conversion efficiencies.
