Researchers at EPFL (Ãcole Polytechnique Fédérale de Lausanne) in Switzerland have stabilized perovskite solar cells by integrating metallic element rubidium into them, driving power-conversion efficiency to a staggering 22%.
The research outlines the integration of rubidium cations into perovskites; The perovskites maintained stability for more than 500 continuous hours in full sunlight at 85°C. The project team has already submitted a patent based on their innovation.
The team stated that perovskite cells built with rubidium make available voltage close to the so-called thermodynamic limit, which is the theoretical maximum efficiency of converting sunlight to electricity.
