Abstract

AbstractA new multidonor and multianchoring asymmetric tribranched organic photosensitizer (i.e., TB‐PT) for dye‐sensitized solar cells containing three different (D–π–D, D–π1–A, and D–π2–A; D = electron‐rich moiety, A = electron‐poor moiety, π = conjugated bridge) polar branches, two donor cores, and two acceptor/anchoring groups to TiO2 was investigated and compared with the corresponding symmetric dyes. TB‐PT combines the advantages arising from its π‐extended tribranched architecture and the intramolecular cosensitization approach, which results in enhanced tailored optical and energetic properties and, eventually, photovoltaic performances.
