A Dye-sensitized Nanocrystalline Solid State Photovoltaic Cell

Laboratory of photochemistry, Center for Molecular Sciences, Institute of Chemistry, Chinese Academy of Sciences, Beijing 100080

Received Date: 23 February 2000

A new type of dye-sensitized nanocrystalline solid state photovoltaic cell based on the wide band gap n-TiO₂/p-Cul heterojunction was fabricated.Tetra-carboxyphenyl porphyrine (TPP-(COOH)₄), squarylium cyanine derivative (SQ-(CH₂)₃^-SO₃Py⁺) and ruthenium bipyridyl complex (RuL₂ (NCS)₂) were used as photosensitizers.Larger photocurrents and photovoltages were shown in the cell sensitized by ruthenium bipyridyl complex and can be further increased by intercalation of a TiO₂ thin underlayer.
