Abstract Scope |
The microstructure of the polymer blend (active layer of Organic Photovoltaic cell) plays a pivotal role in the solar cell performance. Microstructural engineering via the diffuse-interface approach is a robust methodology to unravel the influence of processing parameters on morphology and the subsequent effect on device performance. An efficient methodology for device optimization is proposed, wherein a symbiosis of physics-based and data-driven models is exploited. The combined approach has been able to accurately and efficiently predict the optimal blend composition within an error of 5%. The computational time required to determine the optimal volume fraction for the microstructural dataset through this consolidated methodology is 1,440 core hours, i.e., less than 10% of the physics-based approach that requires 19,500 core hours. Conclusively, the technique proposed in this work is robust as well as efficient for materials design in a wide range of applications beyond thin-film solar cells such as batteries and supercapacitors. |
