KBNNO

KBNNO

Perovskite, a family of minerals with a specific crystal structure, is used in solar cells which are cheaper and more efficient than traditional silicon solar cells when it comes to generating electricity from the sun. The perovskite solar cell is the fastest-advancing solar cell to date, starting with an efficiency of 3.8 percent when it was invented in 2009, to an efficiency of 22.1 percent in 2016. But, perovskite solar cells are dependent on sunlight for it to function efficiently.A team from University of Oulu in Finland discovered KBNNO, a type of perovskite, to have properties that allows it to harness energy from multiple sources at room temperature. KBNNO generates electricity when experiencing changes in temperature, when exposed to sunlight, and when experiencing changes in pressure due to motion. Its properties eliminates the need to add a layer of another material to generate electricity from multiple choices. According to researchers, the properties of KBNNO could be tuned to improve efficiency.KBNNO is outclassed by other perovskites when provided a single source. It is yet to be developed for market use and may not be enough to power houses. But, KBNNO can be more valuable when multiple sources are available. It can push the development of Internet of Things and smart cities and can be applied in electronic devices and ‘smart’ gadgets, eliminating the need for charging cords.Want to know more about this awesome discovery?
