High-throughput combinatorial synthesis of perovskite-type materials for solar applications — •Clemens Petersen, Andreas Rosnes, and Holger von Wenckstern — Centre for Materials Science and Nanotechnology, University of Oslo, Norwa

Recently, combinatorial deposition methods have increasingly gained attention due to the high experimental throughput and resource-wise efficiency they offer in materials discovery. Our combinatorial pulsed laser deposition (c-PLD) approach enables the fabrication of material libraries on a single substrate, spanning wide compositional spaces with precise spatial control. Combined with high-throughput characterization techniques (HTC) such as spatially resolved UV-VIS spectroscopy and X-ray diffraction, the properties of complex materials can be rapidly mapped with high chemical resolution and minimal effort. We demonstrate the potential of c-PLD for accelerating the discovery of perovskite oxides for solar-energy-related applications. Using the SrTiO₃*BaTiO₃ (STO-BTO) system as an example, we showcase rapid screening of structural and optical properties on small area spatially addressable material libraries (SAML) covering the full composition range. In addition, STO-BTO SAMLs enable systematic strain engineering of functional perovskite materials. The tunable band structures and suitability for catalytic processes such as photoelectrolysis and proton-coupled electron transfer render titanate perovskites promising candidates for solar fuel production. Our results underline the capability of c-PLD and HTC workflows to efficiently identify and optimize oxide perovskites for sustainable energy technologies.
