ABSTRACT: The sensitization of TiO2 nanotubes with CdHgTe quantum dots (QDs) was applied by using the direct
dispersion technique. The CdHgTe-QDs were fabricated with different Hg% ratio
in organic medium for controlling their particle size. While TiO2 nanotubes (NTs) were fabricated by anodization technique. The QDs and NTs were
characterized using SEM, TEM and UV-VIS spectrophotometer. In this work, the
photovoltaic parameters of the quantum dots sensitized solar cell (QDSSC)
depend mainly on the Hg% ratio in the QDs. The most efficient QDSSC was
obtained at 25% of Hg ratio with Jsc of 4 mA/cm2, Voc of 0.63 V, FF of 0.32 and efficiency of 0.81%.
