In this work, we studied the blends of metallic nanoparticle and polymers as a donor/acceptor bulk heterojunction active layer. The mobility of the free charge carriers in thin polymer films is lower, so we blended Pd nanoparticles (Pd NPs) into polymers to improve carrier mobility, and enhance the power conversion efficiency of the polymer solar cell. P3HT was used as a donor material because of its high stability and with high absorption in visible light. PCBM was used as a acceptor material because of its high stability and with high electron transportation.
We blended nanoparticles that include different size (5nm and 20nm) and different metal (Pd and Pt) and blended into the P3HT:PCBM active layer, with the device configurations of ITO/PEDOT:PSS/P3HT:PCBM:
Pt NPs/Al. Polymer solar cells measured was under AM 1.5G 100mW/cm2 illumination. When we blended Pd NPs and Pt NPs into the active layer, the power conversion efficiency increased from 2.43% to 2.78%. We will study dispersion and characteristic of different size nanoparticles in the active layer.
