IOP Conference Series: Materials Science and Engineering
In this paper, a study on the fabrication of hybrid polymer solar cells based on organic semiconductor materials P3HT (poly-3-hexylthiophene) and inorganic semiconductor materials TiO 2 (titanium dioxide) has been carried out. The study is focused on the influence of the composition of P3HT and TiO 2 on the optical and electrical characteristics of hybrid polymer solar cells. The composition of P3HT and TiO 2 are varied with ratios of (1:1), (2:1), and (1:2), respectively, in a concentration of
... a concentration of 10 mg/ml. The optical characterization using a UV-Vis spectrometer shows that the higher absorption of the active layer results from the (1:1) ratio of P3HT:TiO 2 . Based on the electrical characterization, using solar simulator on hybrid polymer solar cells, can be concluded that a mass ratio of P3HT:TiO 2 (1:1) gives the best performance, with an open-circuit voltage of 0.2437 volts, a short-circuit current of 0.0029 milliamperes, a maximum power of 0.0002 milliwatts, and a power conversion efficiency of 0.00006%, at the light intensity of 500 W/m 2 .
