Abstract
A stacked electro-optically active organic diode has an anode electrode (), a cathode electrode (), a first electro-optically active organic layer () arranged between the electrodes (), and a second electro-optically active organic layer () arranged between said first active organic layer () and said cathode (). A low electron affinity layer () is arranged between the first electro-optically active organic layer () and the second electro-optically active organic layer (), and is formed of a first transparent inorganic semi-conductor material. A high electron affinity layer () is arranged between said second electro-optically active organic layer () and the low electron affinity layer (), and is formed of a second transparent inorganic semiconductor material, wherein said second transparent inorganic semiconductor material has a higher electron affinity than said first inorganic semiconductor material. The low and high affinity layers () constitute a connection layer of only two semiconductor (sub-)layers which allow for transparent, thick layers, and as a result the diode can be both efficient and reliable.
