Organic solar cells (OSCs) have emerged as a promising solution in pursuing sustainable energy. This study presents comprehensive approach to advancing OSC development by integrating data-driven equations from quantum mechanical (QM) descriptors with physics-informed machine learning (PIML) models. We circumvent traditional experimental limitations through high-throughput QM calculations, prioritizing transparent and interpretable Using the SISSO++ method, we identified key that effectively map relationships between input variables photovoltaic performance metrics. Our innovative predictive models, derived SISSO outputs, excel forecasting critical parameters such short-circuit current (

Abstract The growing importance of high‐speed and energy‐efficient photodetectors in broadband communication has sparked widespread interest organic materials owing to their tunable optical characteristics ease production. However, this Schottky‐type photodetector (OPD) low detectivity a high dark current, requiring additional voltage biasing. Herein, the development highly sensitive self‐powered OPD with metal‐semiconductor‐insulator‐metal (MSIM) structure (ITO/PEDOT:PSS/Organic photoactive layer/dielectric/silver) is presented, using polymer PM6, acceptor Y6, its blend parylene as dielectric layer for spectral detection spanning visible near‐infrared (NIR) range at speeds. Such new class devices can produce fast transient photocurrent signals opposite polarity both under light ON/OFF cycles response pulsed stimuli, which makes inherently more distinguishable. detailed measurements are performed fabricated MSIM different illumination conditions various operational frequencies, PM6:Y6‐based found be most compared single‐component due increased charge generation accumulation without Further, faster time (≈nanosecond) positive negative peaks remarkably cutoff frequency 5.6 MHz outperformed state‐of‐the‐art OPD. extraordinary performance demonstrated by real‐time NIR ASCII codes suggests potential infrared communication. signal offers novel platform next‐generation transient‐type photodetectors, enhancing need biasing across wide applications.

The imperative for achieving commercial success in organic solar cells (OSCs) lies their efficient and stable operation within open-air environments, which enables large-scale production while concurrently reducing manufacturing costs. Poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT:PSS) is usually used as a hole transporting material the conventional configuration of OSCs; however, observations reveal inferior stability due to its acidic hygroscopic tendency. Therefore, introducing transport layer (HTL) replacing PEDOT:PSS essential OSCs. This work highlights both these issues; simple low-cost solution-processed Co3O4 HTL was developed nonfullerene-based OSCs conditions. cobalt(II) acetate tetrahydrate (CATH) adipic acid precursors were synthesize under ambient conditions through one-shot mixing. To control electronic properties thin film, thermal annealing (TA) UV–ozone (UVO) post-treatment employed. with afford an excellent power conversion efficiency 14.13% PM6:Y6 absorber layer, much higher than that (12.62%) CATH (13.01%) counterpart. Interestingly, derived HTL-based OSC exhibited continuous illumination AM1.5G lights In conclusion, this emphasizes pivotal role Co3O4-based HTLs advancing nonfullerene OSCs, contributing advancement toward sustainable photovoltaic technologies.
