Abstract

We demonstrate a solution-processed top electrode for large area organic electronic devices. A Ag nanoparticle solution is spray-coated directly on top of an inverted bulk-heterojunction organic solar cell through a shadow mask. After sintering the Ag nanoparticle film at 150 °C, a temperature which is compatible with processes on flexible substrates, cells show performances comparable to those of reference devices with evaporated top-contacts.
