Abstract: An organic optoelectronic device comprises a substrate having first and second regions, a first electrode positioned over the first region of the substrate, a shutter electrode positioned over the second region of the substrate, an organic heterojunction layer comprising an organic heterojunction material, positioned over at least a portion of the first electrode, an insulator layer positioned over at least a portion of the shutter electrode, an organic channel layer, comprising an organic channel material, positioned over at least a portion of the heterojunction and insulator layers, and a second electrode positioned over the channel layer in the second region of the substrate, wherein the shutter electrode is configured to generate a repulsive potential barrier in the channel layer, suitable to at least reduce movement of charge in the channel layer. A method of measuring received light in an optoelectronic device is also described.

Abstract: 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.

Abstract: An organic light emitting device (OLED) is provided that includes a cathode and an anode; a blue emitting layer; and at least two hybrid red/green emitting layers. One of the at least two hybrid red/green emitting layers is a cathode side, red/green emitting layer that is disposed between the cathode and the blue emitting layer. The second of the at least two hybrid red/green emitting layers is an anode side, red/green emitting layer that is disposed between the blue emitting layer and the anode. The OLED emits white light.
