Developing Novel Optoelectronic Functional Materials by High-Throughput Engineering

EXTENDED ABSTRACT: This study presents the development of novel optoelectronic functional materials using highthroughput engineering techniques. A high-throughput robotic approach is used to grid-search 160 mixed-cation mixed-halide perovskites. The high-quality big data approach allows to uniquely identify the most photo-thermal-stable perovskites under 65 °C/1-Sun illumination. By integrating the most stable perovskites into novel bilayer and polymer-acid-metal structure in perovskite solar cells, we successfully achieve stable unpackaged devices that retain 99% of its peak efffciency after 1450 h of continuous operation at 65 °C in a N2 under illumination [1-2]. A combinatorial magnetron sputtering system is designed with reciprocating rectangular targets, a narrow slit between the substrate and the target, and a quartz crystal microbalance feedback to control the deposition uniformity, resulting in a variation better than 3% across a 76 × 76 mm substrate [3]. Furthermore, the high-throughput anode screening technology was realized based on the above system, which can efffciently screen the best alloy ratio, construct a functional interface layer, effectively improve the stability of the anode, and inhibit the side reaction [4-5].
