Spontaneous spreading movie PCDTBT

Both a low and high amount of solution have been used for spontaneous spreading resulting in a thin or thick active layer. Parent item: Spontaneous spreading of active layers for organic solar cells Movies show the fabrication of active layers for organic solar cells by the spontaneous spreading technique.

Here, a Petri dish is filled with water serving as a substrate for film formation. The resulting film can be transferred to a device substrate. This method allows the fabrication of novel solar cell architectures by transferring multiple layers on top of each other.
