Abstract

We report the photovoltaic response of solid-state devices based on porous TiO2 photosensitized with PbS nanocrystals. A photovoltaic response in the visible and near infrared wavelength range is obtained by exploiting the Schottky junction that forms at the interface between the PbS/TiO2 film and a metallic contact. Spatial images of the photoluminescence and of the short circuit photocurrent signal reveal a non-homogeneous response, which we explain in terms of the electron transfer dynamics at the PbS/TiO2 interface and the morphological properties of TiO2.
