Combining solvents and surfactants for inkjet printing PEDOT: PSS on P3HT/PCBM in organic solar cells

A commonly used strategy in the fabrication of organic electronics involves the use of orthogonal solvents, i.e. the alternating use of organic solvents and water for the application of consecutive layers to prevent dissolution of previous layers. This strategy therefore requires the deposition of sequential layers with a large mismatch in...
