Abstract

Efficient dye-sensitized TiO₂ solar cells based on a 2-thiophen-2-yl-vinyl-conjugated ruthenium photosensitizer and a conjugated polymer poly(3,4-ethylenedioxythiophene) have been fabricated. A maximum power conversion efficiency of 2.6% is achieved when the mesoporous TiO₂ layer is 5–6 μm. The high fill factor (0.74), the open circuit voltage (0.78V), and the linear light intensity dependence of the short circuit current density (4.5mA cm⁻² at 100 mW cm⁻²) make these devices promising for solid state photovoltaic applications.
