Professor Chen Fang-Chung of the NCTU Department of Photonics led a research team to use emerging perovskite materials to create photovoltaic cells for recovering light energy from indoor lighting. Through theoretical calculation and evaluation, the team found that up to 60% of indoor lighting energy can be recovered, creating a clear research goal for energy saving and carbon reduction.
Chen Fang-Chung’s research team pointed out that the high efficiency and low-cost characteristics of perovskite photovoltaic cells can also be applied to low-power sensors or actuators in the Internet of Things. This research outcome, Bandgap Engineering Enhances the Performance of Mixed-Cation Perovskite Materials for Indoor Photovoltaic Applications is published in the October 4 issue of the Advanced Energy Materials, and is selected by the editor for the inside front cover of the issue.
Regarding future prospects, Chen Fang-Chung is optimistic about verifying the correctness of the research direction. The ability to optimize the energy band gap while maintaining the high efficiency of the battery is the next challenge for the team. However, the future goal of achieving a 50% energy recovery efficiency is just around the corner.
