Effective storage solutions are indispensable for harnessing the scattered and intermittent solar energy. The materials field has been employing the Materials Acceleration Platforms to expedite materials discovery. Zhang et al.'s recent work in Nature Synthesis introduced high-throughput nanojunction synthesis and automated photocatalytic screening, which pinpointed the most efficient molecular donor-acceptor combinations. Furthermore, their study bridged the gap between automated screening and large-scale production, boosting the development of scalable sustainable fuels production.
