Dr. Nopporn Rujisamphan co-leads the “Interface and Surface Laboratory (ISC)“ group, which specializes in developing hybrid and all-inorganic perovskite-based solar cell devices. The solar cell performance has reached an impressive efficiency of approximately ∼22.4% (single junction on a solid substrate) and exceeding 16.53% (on a flexible substrate), marking the highest recorded efficiencies in Thailand. The laboratory integrates material design with device fabrication, employing characterization tools such as photoluminescence (PL), time-resolved PL, and external quantum efficiency (EQE) measurements to gain a comprehensive understanding of material properties. The research group utilizes deposition techniques from solutions and vacuum-based, like atomic layer deposition (ALD) and electron beam (E-beam) deposition to ensure the reliability and reproducibility of fabricated layers. In addition to that, research activities in carbon capture development play a crucial role in addressing the global challenge; the research group keens on investigating how the carbon capture can be integrated with renewable energy sources to create a more sustainable and efficient energy grid. Understanding the interface between the perovskite absorber layer and charge-selective contacts is, therefore, very crucial to improving efficiency and stability. The research endeavors include a cutting-edge interdisciplinary approach known as “Computer Intelligence-Aided Device Simulation” and “Density Functional Theory” (DFT) calculations, which is led by Dr. Non Thongprong. This innovative methodology combines computational physics, computer intelligence, and experimental findings to gain profound insights into the fundamental properties of perovskite materials. By leveraging this approach, we aim to advance the development of stable and highly efficient solar cells.
