Abstract:

Lead halide perovskite solar cells have been the focus of interest of scientists in 3rd generation solar energy sector for just over 5 years. Yet, certified energy conversion efficiency rate up to 22.7% (KRICT, Korea Research Institute of Chemical Technology) and stability records over 1000 hours (NREL, US Department of Energy’s National Renewable Energy Laboratory) have already been reported for small photovoltaic (PV) cells. This places emerging perovskite lead halide technology at the forefront of future PV technology. Large scale manufacturing of modules is underway but still faces a number of challenges owing to the very small thickness of the active layers and materials low tolerance for processing conditions. In this work, we address some of the issues related to the fabrication of thin electron collection TiO2 compact and mesoporous layers. Colloids containing small nanoparticles of anatase TiO2 (aqueous synthesis at 80°C, Patm, 30 mins) are used as precursors for the UV-Vis processing of compact and porous TiO2 semiconductor layers, at temperatures compatible with the use of flexible metal or plastic substrates. The role of additive oxalic acid on the formation and properties of these films is investigated. Finally, these colloids are used as media for ink-jet printing of patterned TiO2 semiconductor layers, a feature currently required for optimizing the efficiency of glass-based lead-halide perovskite modules.
