Hsu group research focuses on fundamental science and applications in energy and optoelectronics. We employ solution synthesis for a wide variety of materials and apply short light pulses, instead of heating, for materials processing. Research projects include organic and perovskite photovoltaics, flexible electronics and solar cells, electrical and optoelectronic studies of materials and devices, inorganic materials for extreme UV resists, photonic processing of thin films, and machine learning approaches for synthesis and processing optimization.
