Squarylium Cyanine Dyes for Photoelectric Conversion

Institute of Photographic Chemistry, Chinese Academy of Sciences, Beijing 100101

Received Date: 16 March 1998

Fund Project: This work was supported by the National Natural Science Foundation of China.

Two squarylium cyanine dyes (Sqs) were synthesized to explore their applications in photoelectrochemical solar cells. Nanocrystalline Ti0₂ electrodes modified with Sqs have been prepared to probe the photosensitization effects. A rather high photoelectric conversion efficiency of up to 2.17% and the top incident monochromatic photon-to-photocurrent conversion efficiency (IPCE) of 6.2% at 650nm were obtained from the Sq2-modified nanocrystalline Ti0₂ electrode.
