Diketopyrrolopyrrole-Porphyrin Conjugates as Broadly Absorbing Sensitizers for Dye-Sensitized Solar Cells

A series of four new push–pull zinc porphyrin‐based dyes was synthesised for hybrid photovoltaic solar cells with a view to enhancing the light‐harvesting efficiency at approximately 550 nm with a diketopyrrolopyrrole (DPP) unit. The strength of the donor side of the push–pull porphyrin was tuned by...
