Ng Wen Cai

Dr. Ng Wen Cai is a Postdoctoral Research Fellow in the School of Engineering at Monash University Malaysia. She holds a PhD in Chemical Engineering from Monash University, conferred in 2022, following a Bachelor of Engineering (Hons) in the same field in 2017. Her research is centered on advancing sustainable energy technologies, particularly solar-driven green hydrogen production.

Her research interests focus on renewable energy systems, with an emphasis on solar hydrogen and nanotechnology. Specifically, she investigates the rational design of nanostructured semiconductor-based photoelectrodes for efficient photoelectrochemical water splitting. Her work aims to develop high-performance materials and device architectures that enhance solar-to-hydrogen conversion efficiency, contributing to a low-carbon economy.

The recent publications highlight a strong trend in engineering advanced photoelectrode materials—such as perovskite-MOF hybrids, organic-inorganic heterostructures, and plasmonic semiconductor composites—for solar fuel generation. The research spans materials synthesis, interfacial charge dynamics, and scalable device integration, reflecting a multidisciplinary approach bridging chemical engineering, materials science, and sustainable energy technology.
