| Description |
TiO2 nanorods integrated with poly[2-methoxy, 5-(2-ethylhexyloxy)-p-phenylenevinylene] (MEHPPV) and poly(3-hexylthiophene) (P3HT) matrixes were investigated for charge transport properties to evaluate their potential application in a hybrid solar cell device. An exhaustive characterization was performed to identify the best hybrid nanocomposite among MEHPPV-TiO2 and P3HT-TiO2. The analysis involved optical and electrical characterization techniques such as the X-ray diffraction, field emission scanning electron microscope, energy dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, ultraviolet-visible spectroscopy, photoluminescence, atomic force microscopy, X-ray photoelectron spectroscopy, and I-V measurements. TiO2 nanorods exhibited excellent dispersion in both polymer matrixes, thus significantly improving the photocurrent generation and net efficiency. Therefore, the overall device performance was improved. The findings of this study demonstrated that the P3HT-TiO2 photovoltaic device exhibited superior performance than the MEHPPV-TiO2 photovoltaic device. We believe that this evaluation would certainly contribute to the understanding of interfacial exciton dissociation in nanoscale morphology for the next-generation hybrid bulk heterojunction solar cells.
