N2 - We have investigated the incident-photon-to-current conversion efficiency (IPCE) of thin films of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl- C 61-butyric acid methylester (PCBM) as a function of film thickness, in the presence or absence of silver nanoparticles (AgPs) between the films and the indium-tin-oxide (ITO) electrode. The thickness of the film was evaluated by atomic force microscopy. The absorption and photocurrent action spectra of the films were measured to investigate the effect of the thickness of the P3HT:PCBM film. The results show that IPCE increased steeply in thinner films and the optimal range of thicknesses of the P3HT:PCBM film was 50-120 nm. In this optimal range, the IPCEs were 1.5- 1.8 times larger in the presence of AgPs.
