Transparent Conductive Electrodes

Transparent conductive electrodes (TCE) are an essential part of organic electronic devices such as organic solar cells and organic light emitting diodes, which has a sandwich structure. One of the electrodes must be semitransparent to either let in or let out light. Initially, the most commonly used TCE is indium tin oxide (ITO). Other alternatives for ITO that have been successfully demonstrated include thin metallic films, metal oxide/metal/metal oxide stacks, graphene composites, nanotube composites and conducting polymers. A good candidate for TCE should have an excellent combination of high transparency and low sheet resistance. Additionally, they should be stable to make durable devices, and flexible for applications in flexible electronics.
