A high voltage organic–inorganic hybrid photovoltaic cell sensitized with metal–ligand interfacial complexes

Abstract

A thin solid-state photovoltaic cell of organic–inorganic hetero junctions was fabricated by forming a dye–metal charge-transfer complex as the sensitizer monolayer at the interface of crystalline state organic and inorganic semiconductors. The organic–inorganic hybrid thin-film photocell generates a high photovoltage of 1.2 V, yielding an energy conversion efficiency of up to 1.5%.
