Replacement of hole-transporting materials (HTM) for additive-free perovskite solar cells (PSCs) is an urgent issue. In this work, three new derivatives of dibenzothiophene with methoxyphenyl, trimethoxyphenyl, carbazole moieties are synthesized as hole-transporting materials for PSCs. The hole dens...
