Abstract
The photovoltaic performance (PV) of quantum dot sensitized solar cells (QDSSCs) has been studied by the
addition of gold nanoparticles (Au NPs) at three configuration interlayer positions in the photoanodes. The
resulting photoanodes are (i) Fluorine doped tin oxide (FTO) /Au NPs/TiO2/CdSe QDs,(ii) FTO/TiO2/Au
NPs/CdSe QDs and (iii) FTO/TiO2/CdSe QDs/Au NPs. The TOPO and HDA capping of CdSe QDs has been
modified to be TBAI in order to decrease the CdSe-TiO2 molecular separation. The average size of Au NPs is ~
15nm as measured by HRTEM. Our results show that the configuration with Au NPs deposited directly on FTO
exhibit a noticeable improvement of the power conversion efficiency (PCE) from 0.62% to 1.1%, while the
other two configurations show a slight improvement in their performance. The effect of Au NPs in the three
photonode configurations on the photovoltaic performance are discussed.
