The Interface and Surface Characterization Laboratory (ISC) at King Mongkut’s University of Technology Thonburi (KMUTT), part of the Nanoscience and Nanotechnology graduate program, focuses on developing advanced semiconductor and perovskite solar cell technologies. Our laboratory integrates cutting-edge fabrication methods, including Atomic Layer Deposition (ALD), to produce stable and efficient solar cells. These devices are meticulously assembled and tested within a controlled glovebox environment to ensure precise handling and evaluation under optimal conditions. Guided by theoretical calculations to predict and analyze the properties of various perovskites and related materials, our ISC team identifies the most promising candidates for solar cell applications. Through this approach, we strive to deliver innovations that combine high performance with long-term stability, fostering sustainable advancements in solar energy technology.

Research Highlights
