Researchers at Johannes Kepler University Linz, in Austria, have developed groundbreaking ultra-lightweight, flexible perovskite solar cells.
These photovoltaic cells boast a high power output of up to 44 watts per gram and offer a remarkable efficiency of just over 20%. Their thinness, less than 2.5 micrometers thick, and flexibility make them ideal for various applications, including powering electronics anywhere there is light. The cells have been successfully integrated into a commercial quadcopter drone, allowing it to operate independently without the need for cable recharging. This innovation has vast potential for applications in aerospace, solar power generation in space, search and rescue missions, and solar system exploration.
