What are Perovskite Solar Cells?
Perovskite solar cells are a type of thin-film solar cell that harnesses the power of sunlight to generate electricity. Named after their crystal structure, which resembles that of the mineral perovskite, these cells are composed of a lead-based perovskite material, typically sandwiched between two electrodes. This innovative design enables perovskite solar cells to absorb a wider range of light wavelengths, resulting in higher power conversion efficiency rates.
