High efficiency hybrid solid state blended dyes sensitized solar cell based on zinc oxide nanostructures
This paper reports on the development of high efficiency hybrid solid state blended dye sensitized solar cell (HssBDSSC) using ultrasonification process. Cell synthesized using conducting organic polymer as organic hole-transporting material together with BDs, while Poly (3-Octylthiopehene) (P3OT) and zinc oxide nanostructures (ns-ZnO) as electron-transporting material. BD is made in a composition, so that it can absorbed light in the entire visible region and provided the high electron injection. The HssBDSSC device structure such as indium tin oxide (ITO)/PEDOT:PSS/ns-ZnO+P3OT/BDs/Electrode is developed and an ultrathin layer of PEDOT:PSS is deposited on ITO for making Schottky contact. Device shows a very high conversion efficiency of 4.67&percent;, Fill Factor (FF) 52.9&percent;, open-circuit photo voltages 0.58 V and short-circuit photocurrents 15.1 mA/cm2 under 100 mW/cm2 visible band illumination. We propose an energy level alignment diagram to understand the photophysics of hybrid nanocomposites, which include charge carriers generation, separation, and transfer processes.
