Novel polyene dyes for highly efficient dye-sensitized solar cells

Abstract

We have developed an efficient and novel polyene-dye-sensitized nanocrystalline TiO₂ solar cells producing a 6.8% solar energy-to-electricity conversion efficiency (η) under AM 1.5 irradiation (100 mW cm⁻²): short-circuit current density (J_sc), 12.9 mA cm⁻², open-circuit photovoltage (V_oc), 0.71 V, fill factor (ff), 0.74.
