Lead-free Perovskites: Toward an Opto-Electronics based on Abundant Elements and Low Temperature Synthesis
Résumé
Perovskite named after the Russian mineralogist L. A.Perovski. Their simple and flexible structure ABO3 fits to be doped with elements from all the periodic table. Many different materials are being developed and gradually adopted for high-performance perovskite solar cells (Rapid increase in efficiency ; from 3,8% in 2009 to 30% in 2022). The main issue is their toxicity due to lead. However their low cost production, non-toxicity, simplicity and scalable manufacturing make them promising candidates for optoelectronics of future generation.
