Microelectronics researchers at the University of Oulu have discovered a type of the mineral perovskite which makes it possible to convert sunlight, heat and motion into energy simultaneously. The material makes it possible to solve the energy demands of small appliances and sensors without the need to charge them at all from the electrical grid.
The results of the research by the group were published in Applied Physics Letters on 6 February 2017. The findings have since then been widely publicized in major science media all over the world. World Economic Forum published a video on the results of the study at the end of last week.
Researchers call this perovskite type KBNNO. It is a ferroelectric material like all perovskites. The research project led by Marie Curie Research Fellow, Dr. Yang Bai discovered that the composition of KBNNO can be modified to maximize its various capabilities to generate electricity. The project aims to build a prototype of a multi-energy-harvesting device.
