Organic photovoltaic devices incorporating nanostructures in the photoactive layer: Towards clean solar energy generation

In this article we report the nanostructures formation in the thin films of several organic semiconductors. The thin films have been deposited onto glass substrates by a solution processable of spin-coating technique. The nanostructures are obtained by applying a simple surface solvent treatment pro...
