Organic photovoltaic cells (OPVs) and their compositions are described herein. In one or more embodiments, the OPV or solar cell includes a first electrode (e.g., cathode); a second electrode (e.g., anode); an active layer positioned between the first electrode and the second electrode; and a channel layer positioned between the first electrode and the active layer, wherein the channel layer is configured to laterally disperse a charge across the channel layer. In certain examples, the first electrode is arranged in a grid structure having a plurality of electrode segments and a respective opening between adjacent segments of the first electrode.

Organic photovoltaic device having a lateral charge transport channel

An organic light emitting device is disclosed whose emissive layer has a host material, a first emissive dopant, and a second dopant. The second dopant is an excited energy state managing dopant provided in an amount between 2-10 vol. % of the emissive layer and has a lowest triplet state energy level, T, that is higher than a lowest triplet state energy levels, T, of both the host and the first dopant and lower than the multiply-excited energy level, T*, of the first dopant.

Organic electroluminescent materials and devices

Disclosed herein are stable 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 having a sufficiently high glass transition temperature, e.g., higher than the temperature or temperature range at which the device typically operates, higher than a highest operating temperature of the device, higher than a threshold temperature value, etc. 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).
