Abstract

The properties of soluble zinc phthalocyanines with trifluoroethoxy substituents (TFEO-ZnPcs) were studied to evaluate their possible use in organic thin-film solar cells. We prepared five TFEO-ZnPcs with different numbers and positions of the TFEO substituents. The solubilities, UV-visible absorption spectra, and cyclic voltammograms of these ZnPcs varied with their substituents. TFEO-ZnPc thin-films fabricated by spincasting exhibited photocurrent generation at wavelengths between 600 and 850 nm. Flat heterojunction solar cells consisting of a poly(3-hexylthiophene) (P3HT) layer as a donor and a TFEO-ZnPc layer as an acceptor exhibited photocurrent generation over a wide range of wavelengths corresponding to both the P3HT and TFEO-ZnPc absorption spectra. The best solar cell performance was obtained with (-TFEO)4ZnPc film.
