Perovskite solar cells are a type of solar technology that use a unique crystal structure, known as perovskite, to absorb sunlight and convert it into electricity. These materials are typically made from a combination of organic compounds and inorganic elements, which allows for efficient light absorption and easy manufacturing. One of the main advantages of perovskite solar cells is their potential for high efficiency at a lower cost compared to traditional silicon solar cells. They can be produced using simpler processes, making them an attractive option for future solar energy applications.
