I am a PhD student in Professor Xinhui Lu’s group at CUHK, researching all-polymer organic solar cells. My work focuses on tuning device performance and uncovering multiscale morphology using GIWAXS and GISAXS. I aim to integrate neutron scattering as a complementary tool to enhance contrast between donor and acceptor phases and explore solution-state pre-aggregation behavior. Through this summer course, I hope to deepen my knowledge and connect with others passionate about organic electronics.
