Photoelectrochemical Biofuel Cell Using Triarylamine Dye-Sensitized Titanium Dioxide Film as Photoanode

Article Preview

Abstract:

A Photoelectrochemical Biofuel Cell (PEBFC) generating electrical energy directly from sunlight and biomass was investigated. In this paper,the PEBFC had a triarylamine dye-sensitized titanium dioxide(TiO2) film photoanode and Pt black cathode. The electron transport process of the PEBFC was also described. The performances of the PEBFC were obtained by photocurrent–photovoltage characteristic curves.The open-circuit photovoltage(Voc), the short-circuit photocurrent (Isc) and the maximum power density (Pmax) was 0.82V, 69.00 μAcm-2 and14.00μWcm-2 at 0.27 V, respectively. The fill factor (FF) was 0.25 and the incident photo-to-current efficiency (IPCE) was 3.5% at 441 nm.
