Despite their potential, perovskite structures face several challenges. One of the primary concerns is their [stability](). Perovskite materials can degrade when exposed to moisture, heat, and light, which can limit their practical applications. Researchers are actively working on developing more stable perovskite compositions and protective coatings to address this issue. Additionally, the presence of lead in many perovskite materials raises environmental and health concerns, prompting the search for [lead-free]() alternatives.
