title: Electrochemically intercalated indium-tin-oxide/poly(3-hexylthiophene): A solid-state heterojunction solar cell.
abstract: A heterojunction solar cell design composed of poly(3-hexylthiophene) (P3HT) and intercalated indium-tin-oxide (ITO) donor-acceptor system is explored for the first time. Substantial change in band edge of ITO is noticed after intercalation. Structural and surface morphological studies are reported. Due to tuned band gap of ITO, an increase in short circuit current from 0.0012 to 0.46 mA/cm(2), fill factor from 0.39 to 0.51, and power conversion efficiency from 0.000 367 to 0.3% is obtained for heterojunction solar cell when compared to P3HT alone. This novel, room temperature design approach would be of great scientific interest in current solid-state solar cell scenario.
