Organic solar cells have development of new materials is compulsory to enhance the report of the solar spectrum and the absorption coefficients, which can improve the lower power conversion efficiency and lower photo current as compared to the cases of inorganic solar cells. The polymer of pyrrolo[3,2-b]pyrrole-2,5-dione, exhibits much attention as the electron poor unit for the production of electron-donor material for organic solar cells. Pyrrolo-[3,2-b]pyrrole-2,5-dione unit, region isomer of the known pyrrolo[3,4-c]pyrrole-1,4-dione, is originated from the structure of stable synthetic pigment. The organic low band gap molecules with pyrrolo-[3,2-b]pyrrole-2,5-dione, thiophene and triphenyl amine units were synthesized using Suzuki reaction to generate SM-B, SM-M and SM-H. The spectrum of SM-B confirms absorption band with maxima of 356 and 517 nm, and the onset peak at 667 nm, matching to band gap of 1.86 eV, respectively. The device blending SM-B and PC71BM (1:4) explained a VOC of 0.79 V, JSC of 6.04 mA/cm2, and a FF of 0.33, exhibits power conversion efficiency of 1.56%.
