Fundamental advances to increase the efficiency as well stability of organic photovoltaics (OPVs) are achieved by designing ternary blends, which represents a clear trend toward multicomponent active layer blends. The development high-throughput and autonomous experimentation methods is reported for effective optimization polymer blends OPVs. A method automated film formation enabling fabrication up 6048 films per day introduced. Equipping this platform with Bayesian optimization,...
Abstract Stability of perovskite-based photovoltaics remains a topic requiring further attention. Cation engineering influences perovskite stability, with the present-day understanding impact cations based on accelerated ageing tests at higher-than-operating temperatures (e.g. 140°C). By coupling high-throughput experimentation machine learning, we discover weak correlation between high/low-temperature stability stability-reversal behavior. At high temperatures, increasing organic cation...
