Although conjugated polymer devices can utilize the convenient solution process, the structures can not be preciously controlled due to the seriously dissolved problem between layers when we try to fabricate multi-layer structures. It is an obstacle to the applications of conjugated polymer devices. There are some polymers which are synthesized for multilayer fabrication purpose. Nevertheless, the device, made by these special polymers, performance is poor, and the variety is not much. Most important of all, the research expense for these special polymers is big. In order to overcome the dissolved problem, we use a buffer layer to let the first polymer layer avoid being damaged by the second polymer layer. Through the proof of the thickness measurement, it can effectively overcome the seriously dissolved problem between layers. It is a simple physical process and can apply to any kind of polymer devices in the future. In this paper we had success made multilayer device for WPLED,which yield reached 2.8cde/A.
