Abstract

The invention relates to a photodiode, like an photovoltaic (OPV) cell or photodetector (OPD), comprising, between the photoactive layer and an electrode, a hole selective layer (HSL) for modifying the work function of the electrode and/or the photoactive layer, wherein the HSL comprises a fluoropolymer and optionally a conductive polymer, and to a composition comprising such a fluoropolymer and a conductive polymer.
