We report the photovoltaic response of solid‐state devices based on porous TiO 2 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/TiO 2 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/TiO 2 interface and the morphological properties of TiO 2 .
