Organic solar cells (OSC) were made from blend films of regioregular poly(3-hexylthiophene) (P3HT) and methanofullerene (PCBM) sandwiched with a nanocrystalline TiO2 (nc-TiO2) layer.Indium-tin oxide (ITO) coated glass was used as a transparent electrode and aluminum thin film-as the second electrode.A laminar OSC with a structure of ITO/P3HT/TiO2/PCBM/Al was made for characterization of photo-electricity conversion efficiency (PEC).
