Multilayers of different aggregate-nanoparticles compositions were utilized to improve the sensitized dye solar cells (DSC) by light confinement in the layer. Four different aggregate-nanoparticle composite were integrated as the photoelectrode material of DSCs and their performance and physics were investigated. pastes of different composition ratios films were screen-printed onto transparent conducting oxide (TCO) glass and assembled into test cells. I-V characterization was conducted using solar simulator. Electrochemical impedance spectroscopy (EIS) was utilized in order to measure electron transport properties. Measurement for the quantum efficiency and spectral response of the DSCs were performed using incident photon-to-electron conversion efficiency (IPCE). DSC test cell with an optimized configuration recorded the highest overall power conversion efficiency of 4.22% under the irradiation of 100 mW/cm2 of AM 1.5 simulated sunlight.
