Research interests:

My research interest lies in the field of solar photovoltaic, particularly in multicrystalline silicon, with the objective to improve the material quality of multicrystalline silicon so that solar cells made from multicrystalline silicon can reach higher efficiency. My research focuses on characterising various carrier recombination mechanisms in multicrystalline silicon materials using advanced characterisation techniques, and developing methods to reduce their detrimental impacts to the final cell performance. Hydrogen is known to interact with defects and impurities in silicon (Si), passivate dangling bonds and reduce their recombination activities. It is particularly important for solar cell application. My research interest is to measure, characterise and understand the role of hydrogen in solar cells.

Bio:

Kelvin Sio received his PhD degree in Engineering in 2016 from the Australian National University. Since then, he is working as a researcher fellow. He received ACAP research fellowship in 2017. He has given multiple presentations at international conferences. He is currently the leading investigator for the project"Advanced multicrystalline silicon for high efficiency solar cells", which involve close collaboration with one of the world’s largest PV manufacturers, Jinko Solar, based in China.
