Abstract : According to the Saudi Arabia vision 2030 this vision became a dream of our people. From this regard we wanted to follow this dream for auspicious future through the devotion of an ambitious idea to develop a smart flexible solar cell based polymeric materials for clean energy production. Conjugated polymers have shown great encouragement as an alternative for conventional semiconductors for flexible optoelectronics owing to their light weight and high flexibility. Therefore, a novel hybrid polymer blends have been developed throughout the incorporation of phenyl-C61-butyric acid methyl ester (PC71BM), and indene-C60 bisadduct (ICBA) with various concentrations into the matrices of poly(3- hexylthiophene-2,5-diyl) (P3HT). The structure and morphology of developed films have been characterized via Fourier transform infrared spectroscopy, X-ray diffraction and atomic force microscopy. The impact of PC71BM and ICBA on the optical absorption and emission of the P3HT was emphasized. Solar cells have been manufactured through the including of the ICBA into the P3HT and including the PC71BM into the P3HT at various concentrations. It was found that the P3HT:PC71BM at blend ratio (1:1.2) achieved conversion efficiency of 4.7% and the P3HT:ICBA (1:0.5) exhibited conversion efficiency of 5.2%. A flexible solar cell was manufactured using ternary solar device composed of P3HT:ICBA:PC71BM (1:0.5:1.2) and showed efficiency of 6.3%. Furthermore, an improvement could be successfully achieved through the construction of tandem solar cell device composed of ITO/ZnO/P3HT:PC71BM(1;1.2)/PEDOT:PSS/ZnO/P3HT:ICBA(1:0.5)/MoO3/Ag. This tandem solar cell achieved solar conversion efficiency of 8.1%. Therefore, a promising flexible tandem solar cell was manufactured for the next generation with outstanding conversion efficiency.
