摘要：

In this work, the focus is on the modification of titanium dioxide (TiO2) photoanode in dye-sensitized solar cells (DSSCs) by mixing the TiO2 with plasmonic gold (Au) nanoparticles with the aim to enhance the performance. Different concentrations of Au nanoparticles were incorporated into TiO2 and their J-V characteristics have been taken under white light intensity of 100 mW cm(-2) to obtain the optimum concentration. DSSC made from commercial ruthenium based dye (N3) with TiO2 containing 40 mu L Au photoanode and liquid electrolyte (iodolyte Z-50) exhibited the J(sc) of 17.52 mA cm(-2), V-oc of 0.62 V, FF of 0.64 and efficiency, eta of 6.97 %. The photovoltaic parameters in terms of J(sc) and eta have showed improvement by 83% and 68%, respectively. The enhanced performance is due to more photocurrent have been generated as a result from the plasmonic effects of Au nanoparticles that improved the light absorption and scattering.
