Perovskite solar cells are a type of solar technology that use a specific crystal structure, known as perovskite, to convert sunlight into electricity. They are made from a combination of organic materials and inorganic compounds, which allows them to be produced at a lower cost compared to traditional silicon-based solar cells. Their unique properties enable high efficiency in converting sunlight, making them a promising alternative in the renewable energy sector. These solar cells can be manufactured using simpler processes, such as printing techniques, which can lead to flexible and lightweight panels. Research is ongoing to improve their stability and longevity, addressing concerns about their durability in various environmental conditions.
