Organic photovoltaic cells (OPVs) and their compositions are described herein. one or more embodiments, the acceptor with an active layer of an OPV includes is a non-fullerene acceptor. Such non-fullerene acceptors may provide improved OPV performance characteristics such as improved power conversion efficiency, open circuit voltage, fill factor, short circuit current, and/or external quantum efficiency.

Disclosed herein are organic photosensitive devices including at least one exciton-blocking charge carrier filter. The filters comprise a mixture of at least one wide energy gap material and at least one electron or hole conducting material. As described herein, the novel filters simultaneously block excitons and conduct the desired charge carrier (electrons or holes).

A method for fabricating an organic electronic device comprises providing a plurality of photoresist structures on a substrate, the substrate having a first electrode layer, the photoresist structures having a bottom surface attached to the substrate and a top surface opposite the bottom surface, the top surface having a dimension greater than a dimension of the bottom surface, positioning a mask over the structures, the mask having a plurality of openings, and depositing an emissive material over the substrate through at least one of the plurality of openings to form at least one emissive element. An organic electronic device and a method of fabricating an organic electronic component are also described.

An optoelectronic system comprising a flexible optoelectronic device, wherein the device comprises a flexible plastic substrate, a coating comprising a glass or a polymer, positioned over the flexible plastic substrate, an anode and a cathode positioned over the coating, an organic heterojunction positioned between the anode and the cathode, comprising a donor material and an acceptor material, and an encapsulating layer comprising a glass or a polymer, positioned over the anode and the cathode. The device further comprises a roller configured to roll the flexible optoelectronic device into a stored position and a frame configured to mount the roller and the optoelectronic device.
