Abstract
The present invention discloses a polymer-metal compound composite ink, a preparation method and application thereof. The composite ink comprises: at least one polymer; at least one metal compound material, the metal compound material being selected from polyoxometalate compounds and nanocrystalline metal oxides; at least one solvent which is used for forming a disperse system in the form of a uniform fluid together with the remaining components in the composite ink. The present invention also discloses a method for preparing the composite ink. The composite ink of the present invention is easily available in raw material, easy to prepare and low in cost, and can be manufactured into a composite thin film by spin-coating, printing or in other ways. The composite thin film, as an electrode modification layer, can be applied to photoelectric devices such as solar cells or light-emitting diodes, so as to improve the contact performance between an electrode and an organic active layer and thus enhance the performance and yield of photoelectric devices.
