Perovskite solar cells are a type of solar technology that use a specific crystal structure, known as perovskite, to absorb sunlight and convert it 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 efficiency in converting sunlight into energy has rapidly improved, 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. Additionally, they can be integrated into various surfaces, including windows and building materials, expanding their potential applications. Researchers continue to explore ways to enhance their stability and longevity for commercial use.
