Abstract
The invention provides an electronic device including an anode and a cathode, between which there are at least two organic phototransducing units where the units are separated by an intermediate connecting region which comprises in sequence: an organic p-type layer, an intermediate layer in direct contact with the organic p-type layer and including a compound that has a LUMO more negative than −3.0 eV and is different from the organic compound in the organic p-type layer, and an n-type doped organic layer in direct contact with the intermediate layer and including an electron transport material as a host and an organic n-dopant with a HOMO less negative than −4.5 eV. In one embodiment, the electronic device is a tandem OLED.
