ABSTRACTSolid state PbS Quantum Dots (QDs)/TiO2 Nanoparticles heterojunction solar cells were produced by depositing PbS QDs on a 500nm thick Mesoscopic TiO2 films using layer-by-layer deposition. The heterojunction solar cells show photovoltaic response from the visible to the near infra-red region. Importantly, the PbS QDs act here as photosensitizers and at the same time as hole conductors. The PbS QDs/TiO2 device produces a remarkable short circuit photocurrent (Jsc) of 16.3 mA/cm2, an open circuit photovoltage (Voc) of 0.54 V and a fill factor (FF) of 0.41, corresponding to a light to electric power conversion efficiency (η) of 4.04% under 0.9 sun intensity.
