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

摘要

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(TiO_2) 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(V_(oc)), the short-circuit photocurrent (I_(sc)) and the maximum power density (P_(max)) 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.
