Dye-sensitized solar cells based on low cost nanoscale carbon/TiO2 composite counter electrode

Abstract

A dye-sensitized solar cell based on low cost nanoscale carbon/TiO2 composite counter electrode was fabricated and its photovoltaic performance (η = 5.5%, AM 1.5, 91.5 mW cm−2) was comparable to that from platinum counter-electrode devices (η = 6.4%, AM 1.5, 91.5 mW cm−2) made at similar conditions.
