A spin coater is a device used to apply a thin, uniform layer of liquid material onto a substrate by spinning it at high speeds. This method relies on centrifugal force to spread the liquid evenly across the surface, making it an effective technique for creating films that are essential in various applications, including organic photovoltaics. The speed and duration of the spin process can be adjusted to control the thickness of the film, which is crucial for optimizing the performance of the final product.
