Abstract

• Nanoscale metal structures embedded in DSSC devices could also potentially be beneficial in improving the light absorption, as well as the charge separation and charge collection processes. In this research, TiO2 was used as a photoelectrode and eosin y is used as photosensitizers. Using a Mayer rod coating method, a highly viscous titanium dioxide (TiO2) paste was deposited on a FTO glass substrate. Metal nanowire such as silver nanowire (Ag NWs) was coated on the TiO2 active layers to enhance the photon absorption and charge separation efficiency. The structural properties of the Ag NWs coated TiO2 active layer were studied by using XRD and SEM techniques. Photovoltaic parameters such as short circuit current, open circuit voltage, fill factor FF, and efficiency were determined under light intensity of 11 mW/cm2 .
