About Us

The Interface and Surface Characterization Laboratory (ISC) at King Mongkut’s University of Technology Thonburi (KMUTT) in a nanoscience and nanotechnology graduate program primarily concentrates on advancing semiconductors and perovskite solar cell technology. This laboratory employs sophisticated theoretical models, particularly Density Functional Theory (DFT) and Drifted Diffusion Simulation models, to anticipate and analyze the characteristics of various perovskites, and other related materials/layers. By using the above theoretical insights, our ISC team can effectively pinpoint the most suitable candidates for solar cell applications. The goal of these experimental procedures is to ensure that the solar cells not only achieve superior performance but also maintain consistency and reliability, aiming for innovations that are both efficient and sustainable.

Inside Back Cover: This work introduces a technique for making perovskite solar cells (PSCs) by adding a 2D layer to a 3D structure without post-production annealing. This method, involving a single crystal perovskite and a mixture of methylammonium lead iodide and butylammonium iodide in tetrahydrofuran, leads to surface healing and 2D formation. The findings are backed by density functional theory and experimental results.

Inside Back Cover: The most fundamental properties of photovoltaic materials are impacted by the photoinduced charge separation behavior, which can be improved by modifying the underlying layer that the perovskite is prepared on top. In article number 2201632, Non Thongprong, Nopporn Rujisamphan, and colleagues investigate the impacts of using alkali salts on porous TiO2 from experimental and computational points of view to provide a better understanding of such surface passivation.

Cover Picture: In article number 2200964, Non Thongprong, Thidarat Supasai, Nopporn Rujisamphan, and co-workers presented the pseudohalide salt of sodium tetrafluoroborate, whose anions have a higher electronegativity than other halide salts, with the potential to passivate the surface of tin oxide while enhancing the optoelectronic properties of a perovskite film. The current study presents a facile and effective method for enhancing the moderate thermal stability and performance of solar cell devices.
