| Research Abstract |
Low-cost organic thin film solar cells were fabricated using unsubstituted polythiophene as an active layer. Bilayer devices prepared by electrodeposition of polythiophene on a transparent electrode followed by spin-coating of fullerene derivatives showed a maximum power conversion efficiency of 1.5% under simulated solar light irradiation. Project-based learning was conducted in a college class using the fabrication of this type of solar cell as a project. The use of liquid Ga-In alloy as a cathode material enabled the fabrication of solar cells with power conversion efficiencies of 0.2 to 0.4% in conventional classrooms.
