The laboratory for interface and surface (ISC) theme is related to fabrication and characterization on nanometer-scale materials, state-of-the-art in nowadays semiconductor technology, and semiconductor materials for solar cell devices. The research group at the ISC KMUTT focuses on the optical and electrical properties of emerging semiconductors, including halide perovskites. The research group related the optoelectronic properties to chemical, material morphological, and structural properties through multimodal characterizations. That fundamental scientific understanding allows constructing, up to now, perovskite solar cells with their power conversion efficiency of over 21%.

In addition, we have been working on the so-called “Computer Intelligence-Aided Device Simulation, “which is a novel interdisciplinary research approach using a combination of computational physics, computer intelligence, and experimental results. This approach will provide us with insights into the fundamental properties of perovskite solar cells in our fabricated devices and promote the development of stable high-efficiency solar cells.

We are looking for enthusiastic M.S. and Ph.D. students to work on a project together. Please apply to our Nanoscience and Nanotechnology Graduate Program, Faculty of Science, KMUTT.



Unveiling the Influence of the Spectral Irradiance of Indoor Light-​Emitting Diodes on the Photovoltaics of a Methylammonium Lead Iodide-Based Device

In article number 202100143, we highlight the impacts of the correlated-color temperatures (CCTs) of light-emitting diodes (LEDs) on the perovskite solar cell (PSC). Based on the irradiant spectrum, an emphasis is placed on the theoretical prediction of the free carrier generation rate and maximum current density as a function of the CCT. Most importantly, when compared to the PSC device illuminated under one-sun conditions, more stable maximum power output was obtained under LED illumination.
