132487Surface Treatment of Perovskite Solar Cell Inorganic Titania Meso-Porous Substrates (STOPIT)ClosedFeasibility StudiesInnovate UKThis collaborative early stage project focuses on investigating the potential of developing higher efficiency stable perovskite solar cells (PSC) by the improvement of the meso-porous Titania cathode substrate structures by surface treatment processing. Various methods will be utilised to realise the surface treatments and fully processed PSCs will be fabricated and tested to verify the performance and stability benefits. This collaborative R&D project will focus on improving the efficiency, stability and processing of the PSC technology, in order to move towards developing viable and manufacturable thin film PSCs suitable for implementation in the Building Integrated Photovoltaic (BIPV) market. Building on existing perovskite PV material stack technologies; new process methods and the incorporation of improved electronic layers will be explored, developed and tested. The benefits will also include lower cost (<$0.2/ Wh) and an expected improved stability and scalable processing routes for manufacturing. It will secure a UK R&D capability with the key supplier of technology and materials for perovskite solar cells with the support of the HVM Catapult and its facilities.
