Thermal metal deposition induces segregation in polymer thin films: a demonstration on OPVs†
Abstract
Interfacial interactions between thermally evaporated metal atoms and a polymer can induce its segregation to the polymer blend/metal interface. This segregation effectively modifies the surface composition, originally directed by surface energy considerations during film formation, and can be utilized to enhance device performances as demonstrated here for polymer solar cells.
