We investigate novel materials and device photophysics via advanced spectroscopy as a powerful tool to understand their characteristics in different length and time scales, unveil the origin of instability and maximize the output of the advanced energy devices.  We are very keen in exploitation of our research into actual products and bridging the gap between fundamental science and technology commercialization. We have active industrial collaborations for technology transfer into multiple emerging markets including photovoltaics, the Internet of things (IoT) and consumer electronics. Our research activities cover three main multidisciplinary themes where most projects in the group fall within one or several of these categories, making the sub-sections a good resource for prospective applicants to understand the activities in the group.
