Machine learning is profoundly reshaping how we approach scientific research, offering new opportunities to both accelerate and enhance traditional methodologies. This shift is also significant in materials science, where the complexity of understanding material properties and optimizing manufacturing processes has long posed challenges. The application of machine learning techniques is now enabling faster discovery, more accurate predictions, and better-informed decision-making [1]. In the context of photovoltaic devices—where the efficiency of material properties directly impacts the device performance—this technological revolution is proving to be especially valuable.
In this presentation, I will delve into the application of generative models, a subset of machine learning, and their role in enhancing the speed and accuracy of numerical simulations aimed at exploring material properties, in particular dynamical properties. These machine learning models can significantly accelerate numerical simulations by identifying internal relevant material degrees of freedom [2]. Additionally, I will discuss how machine learning techniques are being used to analyze and process experimental data [3,4]. Often, experimental data can be noisy or incomplete, and integrating it with simulation results can be a complex task. However, by leveraging machine learning algorithms, it becomes possible to identify hidden patterns, fill in missing information, and reconcile experimental measurements with theoretical models. This integration enables the creation of a unified data stream that provides a comprehensive view of material performance, encompassing both simulated predictions and real-world observations. The goal of combining generative models with data analysis is to streamline the entire research process, from simulation to experimentation [5]. This approach reduces the time and resources traditionally required to design, test, and optimize new materials, especially in fields like photovoltaics, where improving efficiency is crucial. By using machine learning to accelerate these steps, we can significantly shorten the cycle time for the development of advanced materials, driving innovation in energy technologies and beyond.
