Dr Shaoyang Liu

Shaoyang is a Postdoctoral Fellow in Tandem Photovoltaic Interfaces, working on the OMEGA Singlet Fission project. His current research focuses on improving the efficiency of silicon solar cells by enabling carrier multiplication in an organic capping layer. As a key member of the silicon device and interface teams, he investigates charge transfer from the organic layer into silicon solar cells and develops device structures designed to maximise the efficiency of this process.

Shaoyang completed his PhD on the characterization and kinetics of light- and elevated-temperature-induced degradation (LeTID) in low-cost silicon materials. His doctoral research combined lifetime characterization, device-level analysis, and degradation kinetics to better understand the mechanisms underlying performance losses in silicon solar cells. During his PhD, he improved a high-intensity laser system for mitigating light-induced degradation in PERC solar cells, investigated the root causes of LeTID using multicrystalline silicon lifetime samples and finished devices, and collaborated with industry partners including Jinko, Aiko, and Chint on hydrogen passivation solutions to enhance silicon solar cell stability.
