Materials Science
Sustainable design of organic solar cells utilized machine and deep learning
This research optimizes organic solar cells (OSCs) using SCAPS-1D simulations and AI models (CNN, SVR). It identifies optimal material thicknesses (PFN-Br at 5nm, active layer at 300nm, PEDOT:PSS at 30-100nm) to achieve a simulated PCE of 19.50%. The CNN model demonstrates superior accuracy in predicting PCE (RMSE 0.1109) and Voc (RMSE 0.00599V) compared to SVR, effectively capturing non-uniform photovoltaic behavior. This integrated approach not only enhances OSC efficiency but also aligns with UN Sustainable Development Goals (SDG 7, 9, 12, 13) by enabling cleaner energy production, reducing material waste, and streamlining design processes through advanced AI.

Optimizing ETL Thickness for Enhanced PCE
The study revealed that a PFN-Br ETL thickness of 5 nm is most effective, achieving a PCE of 12.04%. This optimal thickness facilitates efficient electron extraction and minimizes recombination losses, demonstrating the critical role of precise material dimensioning. Moving from 5 nm to 30 nm, PCE drops to 11.80%, highlighting the sensitivity of device performance to ETL thickness variations and the importance of fine-tuning for maximum efficiency. This insight underscores the power of simulation-driven design for material layers.
Impact of Active Layer Thickness on Performance
Optimizing the active layer (PBDB-T: IT-M) thickness significantly boosted PCE from 10.40% at 80 nm to a peak of 19.50% at 300 nm. Thicker active layers enhance light absorption and Jsc. However, beyond 300 nm, while PCE slightly increases, the Fill Factor (FF) decreases significantly due to increased resistance and recombination, emphasizing the need for a balanced approach between light absorption and charge transport efficiency. The 300 nm thickness represents the sweet spot for maximizing overall device performance.
