Perovskite solar cells are a type of photovoltaic technology that uses a perovskite-structured compound as the light-absorbing layer. The term “perovskite” refers to a specific crystal structure named after the mineral of the same name, which has a general formula of ABX3, where ‘A’ and ‘B’ are cations of different sizes, and ‘X’ is an anion, typically a halide.
Perovskite solar cells are known for their high efficiency and ease of fabrication compared to traditional silicon-based solar cells. They can be made using low-cost materials and can be processed using various techniques, such as solution processing, which allows for flexible and lightweight solar panel designs.
These solar cells have gained significant attention due to their rapid improvement in conversion efficiencies—reaching over 25% in laboratory settings—alongside potential for lower production costs. However, challenges such as stability and long-term degradation under environmental conditions remain topics of active research and development in the field of solar energy technology.
In an exciting development for renewable energy enthusiasts, Korean researchers have significantly advanced perovskite solar cell technology. The Korea Research Institute of Chemical Technology, in collaboration with UniTest Co, has…
