CONNECTION OF PHOTOACTIVE REGIONS IN AN OPTOELECTRONIC DEVICE

摘要

An optoelectronic device has a layered construction, comprising a base layer, a first conductive layer, a photoactive layer and a second conductive layer. Plural separation channels extending through the photoactive layer and the first conductive layer separate the photoactive layer into photoactive regions, and insulator material extends through the respective separation channels to the base layer. Between adjacent photoactive regions, electrical connectors extend inside the lateral extent of the insulator material between a surface of a second electrode that is in electrical contact with one photoactive region to an opposing surface of a first electrode that is in electrical contact with the other photoactive region. By forming the electrical connectors extend inside the lateral extent of the insulator material, the overall size of the connection is minimised.

1. An optoelectronic device having a layered construction, comprising:
a base layer; a first conductive layer on the base layer; a photoactive layer on the first conductive layer and in electrical contact therewith; plural separation channels extending through the photoactive layer and the first conductive layer, wherein, on opposite sides of the separation channels, the photoactive layer is separated into photoactive regions and the first conductive layer is separated into first electrodes in electrical contact with respective photoactive regions; between adjacent photoactive regions, insulator material extending at least through the respective separation channels to the base layer; a second conductive layer on the photoactive layer and in electrical contact therewith separated into second electrodes in electrical contact with respective photoactive regions by gaps extending through the second conductive layer; and between adjacent photoactive regions, respective electrical connectors extending inside the lateral extent of the insulator material between a surface of a second electrode that is in physical contact with one of the adjacent photoactive regions and an opposing surface of a first electrode that is in physical contact with the other of the adjacent photoactive regions.
