Spin coating is a popular technique for producing thin films used in energy materials, especially in applications like solar cells, batteries, and other energy technologies. Known for its simplicity, affordability, and ability to achieve uniform films with precise thickness control, this method involves applying a liquid precursor to a rotating substrate. The centrifugal force then evenly spreads the liquid, creating a consistent thin layer. In energy-related applications, spin coating is frequently used to produce thin films for semiconductors, perovskite solar cells, organic photovoltaics, and electrolytes in batteries or fuel cells. The technique’s precise control over film thickness is crucial for enhancing the performance of these energy devices.
