摘要: Myoglobin (Mb), reconstituted zinc protoporphyrin-apornyoglobin (ZnMb), and eosin-modified ZnMb (EoZnMb) were used as photosensitizers to functionalize TiO(2) nanocrystalline films for biosensitized solar-cell (BSSC) applications. For the Mb-sensitized SC, the poor cell performance was due to a reduction Fe(III) -> Fe(II) that produces a photocurrent density of the device smaller than its unsensitized counterpart. The efficiencies of power conversion of both ZnMb and EoZnMb-sensitized SC were enhanced about ten times due to superior charge separation between TiO(2) and the protein, and due to smaller current leakage between TiO(2) and the electrolyte. The cell performances of the BSSC devices are discussed in terms of an equivalent-circuit model.
