Research Stories

A new fabrication technique for substantially enhancing the prospects of commercialising perovskite solar cells through improved stability, reliability, efficiency and affordability is underway at CityUHK.

A simple “smart food label” can accurately and instantly assess the freshness of food and determine if it has gone off. This helps reduce food waste and eliminate kitchen waste.

CityUHK research team addressed a challenge for scientists for over a decade with creative material science solutions. The team demonstrated an effective strategy to enhance the long-term stability of perovskite-organic tandem solar cells, which can be mass-produced at a speed comparable to newspaper printing, with a daily output of up to 1,000 solar panels.

The Hong Kong Institute for Clean Energy (HKICE) at CityUHK organised the HKICE Summit on Next-Generation Green Energy Materials and Applications, which took place between 13 and 14 June 2024, to explore innovative solutions in green energy production, storage, and utilisation.

Five research projects from CityUHK were granted funds from the HKSAR Government’s RAISe+ Scheme. This demonstrates CityUHK’s commitment to promoting excellence in high-quality research and innovation, driving the transformation of the University’s world-class scientific research into applications, thereby creating commercial and social value.

A few years ago, Dr. Chi-on Ng, a graduate of the Department of Chemistry at City University of Hong Kong (CityUHK), together with his team, developed a new type of photo-sensor that can effectively monitor oxygen concentration in seawater and reduce the monitoring cost. The team subsequently established a start-up company called “NerOcean”.
