Thermoelectric Bi sub(2)Te sub(3)-improved charge collection for high-performance dye-sensitized solar cells

A new dye-sensitized solar cell based on a thermoelectric Bi sub(2)Te sub(3)/TiO sub( 2) composite anode is demonstrated, in which the incorporated Bi sub(2)Te sub(3) nanoplates function as built-in nanoscale electron generators to convert "waste heat" to electricity and as a good photorea...

Description
Summary:A new dye-sensitized solar cell based on a thermoelectric Bi sub(2)Te sub(3)/TiO sub( 2) composite anode is demonstrated, in which the incorporated Bi sub(2)Te sub(3) nanoplates function as built-in nanoscale electron generators to convert "waste heat" to electricity and as a good photoreaction catalyst to enhance the charge transfer rate, resulting in 28% improvement of the overall power conversion efficiency.
