Phenothiazine-based dyes with bilateral extension of π-conjugation for efficient dye-sensitized solar cells

Four novel organic photo-sensitizers based on phenothiazine were designed, synthesized and characterized for efficient dye-sensitized solar cells. Anisole, octyloxybenzene and dodecyloxybenzene were incorporated into the phenothiazine by an Ullmann reaction. An additional octyloxybenzene was incorporated into one dye unit through a Suzuki coupling reaction. The modified phenothiazine moiety acts as an electron donor and cyanoacrylic acid acts as an electron acceptor and anchoring unit. The photophysical, electrochemical and sensitizing characteristics of the new dyes were evaluated. The bis(octyloxybenzene) substituted dye delivered the best performance with its sensitized solar cell displaying an overall power conversion efficiency of 5.73% under standard illumination. The results indicate that bilateral conjugate extension of the π conjugation can increase their light harvesting capacity and electron lifetime, leading to improvements in the efficiency of their dye-sensitized solar cells.

Side-chain effects on phenothiazine-based donor-acceptor copolymer properties in organic photovoltaic devices

A series of new phenothiazine-based donor-acceptor copolymers, P1 and P2, were synthesized via a Suzuki coupling reaction. The weight-averaged molecular weights (Mw) of P1 and P2 were found to be 16,700 and 16,100, with polydispersity indices o
