The potential toxicity of lead is a concern that complicates commercialization of lead-halide perovskites. The photovoltaic performance of lead-free perovskites on the other hand is lagging with respect to the lead-based ones. However, tin-based perovskites have seen substantial improvements in the last years. In addition, perovskite-like materials (e.g. Cs Ag Bi X , Cs Au Au X , Cs Ag Sb Br etc.) are gaining increasing attention because they provide the opportunity to design novel materials with unexplored properties. Therefore, this class of materials is particularly intriguing for applications beyond PV, such as thermoelectric devices, LEDs but also as a platform for photochemical reactions. Despite their potential, a lot is still not known about this class of materials and the large parameter space in the achievable compositions further extend the complexity of their understanding.
This symposium aims at bringing together international experimentalists and theoreticians who are involved in the investigation of lead-free perovskites from their fundamentals to applications.
The symposium invites contributions on new synthesis and growth methods, characterizations of the structural and optoelectronic properties, and theoretical insights. In addition, the symposium aims to discuss the latest advances in lead[1]free perovskite-based devices which include thermoelectrics devices, photodetectors, LEDs, platform for photochemical processes and solar cells, among others.
