Abstract

Bulk heterojunction organic solar cells made of blended of the electron donor (D) and electron acceptor (A) molecules were fabricated using inkjet printing technique with three different D:A ratios i.e. 1:3, 1:1 and 3:1 (weight). Poly (3-octylthiophene-2,5-diyl) (P3OT) and (6,6)-phenyl C 71 butyric acid methyl ester (PC71BM) were used as donor and acceptor respectively. The generated photocurrents and the power conversion efficiency depend on the donor: acceptor ratio, where the device D:A ratio 3:1 generated higher photocurrent. The photovoltaic performance of the devices may also affected by the microstructure and surface morphology of the active layer film.
