Abstract

Novel organic dyes based on the phenothiazine (PTZ) chromophore were designed and synthesized for dye-sensitized solar cells, which give solar energy-to-electricity conversion efficiency (η) of up to 5.5% in comparison with the reference Ru-complex (N3 dye) with an η value of 6.2% under similar experimental conditions.
