Dr Mohammad Khairul Zarifi bin Haji Awang Masri is a lecturer in the Physical and Geological Sciences Programme with a specialization in Physics. He obtained a BSc. degree in Physics at the University of Nottingham in 2004 and a MSc. degree in Materials Physics and Applications at Loughborough University in 2006. For his Masters project, he investigated the high strain rate deformation behaviour of Nickel-Titanium shape memory alloys. He received his PhD from the University of St Andrews in 2015 under the supervision of Prof. Ifor Samuel. His PhD focused on exciton dynamics in organic semiconductors where he examined exciton diffusion and exciton-exciton annihilation in organic semiconductor materials important for organic solar cells using mainly ultrafast laser spectroscopy. Zarifi currently has wide-ranging interests in the field of organic semiconductors for optoelectronic applications. More specifically, he is interested in the study of exciton diffusion and photophysics for enhancing organic solar cell device performance.

FUTURE PROJECTS

Development of high efficiency organic solar cells

Power conversion efficiencies of solution-processed organic solar cells have recently exceeded 14% through the development of novel high-performance organic materials. Further improvements in performance can be achieved with a better understanding of the factors that limit organic solar cell efficiency. This project aims to identify the structure-property relationships that govern organic solar cell performance and gain detailed insights into the approaches for optimizing the structural, morphological, optical and electronic properties of the organic materials.

Interfacial Solar Vapour Generation

Interfacial solar vapor generation (ISVG) has recently emerged as an efficient solar-thermal conversion technology with promising applications in water purification and desalination. Using specially-designed solar evaporators, the heat generated from absorption of solar irradiation can be utilized to vaporize water at the water-air interface. This localized heating at the interfacial region allows for higher solar-to-vapour conversion efficiency compared with conventional solar evaporation systems. This project will focus on designing a suitable ISVG system using low-cost materials and the performance of the ISVG system will be characterized and optimized to gain insight into the best approach to achieve high solar-to-vapour conversion efficiency.

MSc or PhD

Triboelectric Nanogenerators

Triboelectric nanogenerators or TENGs have received a lot of attention over recent years for their potential as an alternative energy-harvesting device. TENGs can harness mechanical energy and convert it into electrical energy through a combination of contact electrification and electrostatic induction. Due to its versatility, TENGs can be designed with various device structures made from a wide selection of triboelectric materials. In this project, the aim is to produce a working TENG using low-cost materials. The device performance of the TENG will be characterized and optimized. Chemical, physical and/or structural engineering approaches will be employed to investigate their effect on device performance.
