Abstract

One major concern for the commercialization of perovskite photovoltaic technology is the toxicity of lead from the water-soluble lead halide perovskites that can contaminate the environment. Here I will present an abundant, low-cost and chemically robust sulfonic acid cation exchange resins (CERs) based method which can prevent lead leakage in damaged perovskite solar modules under severe weather conditions. CERs exhibit both high adsorption capacity and fast adsorption rate to lead in water due to the large binding energy to lead ions in the mesoporous structure. Integrating the CERs with perovskites at different locations have dramatical influence on how strong they prevent lead leakage. I will present several innovations that can reduce the lead leakage from damaged large-area perovskite solar panels to below 7.0 ppb even in the worst scenario that every sub-module is damaged.
