The invention relates to novel organic semiconducting (OSC) random copolymers containing a halo-substituted 4,8-dithiophenyl-benzodithiophene unit and a benzodithiophene-dione unit, to methods for their preparation and educts or intermediates used therein, to compositions and formulations containing them, to the use of the copolymers and compositions as organic semiconductors in, or for the preparation of, organic electronic (OE) devices, especially organic photovoltaic (OPV) devices, perovskite-based solar cell (PSC) devices, organic photodetectors (OPD), organic field effect transistors (OFET) and organic light emitting diodes (OLED), and to OE devices comprising these copolymers or compositions.

Organic semiconductors

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.
