What are Perovskite Solar Cells?

Perovskite solar cells are a type of solar cell that utilizes a perovskite-structured compound, typically a hybrid organic-inorganic lead or tin halide-based material, as the light-harvesting active layer. The crystal structure of these materials, named after Russian mineralogist L.A. Perovski, mimics that of the mineral calcium titanate (CaTiO₃). What makes perovskites so attractive for solar applications is their remarkable ability to absorb a broad spectrum of sunlight and their excellent charge-carrier mobility, meaning that the electrons and holes generated by light absorption can move easily through the material to be collected as electrical current. Unlike traditional silicon solar cells, which require high-temperature, energy-intensive manufacturing processes, perovskite solar cells can be fabricated using low-cost, solution-based methods, such as printing or spin-coating, at relatively low temperatures. This ease of fabrication opens up possibilities for flexible, lightweight, and even semi-transparent solar modules that can be integrated into a wider range of applications, from building facades to portable electronics. The ongoing research in this field is largely driven by the potential for very high efficiencies combined with low production costs, making them a compelling alternative to established photovoltaic technologies.
