Abstract: Disclosed is a method and apparatus for continuous coating with a rotational die in which coating materials flow in a radial direction. The linear speed of a substrate in need of coating is identical to the tangential speed of the surface of the rotational die so that the coating material, which flows in a radial direction of the rotational die, flows onto the substrate perpendicularly. Therefore, the ingredients of coating materials overlap one another (or stand vertically as a layer), and the vertical sequence of the coating material is ensured. This method and apparatus can be used to make organic electronic devices, organic light-emitting diodes and organic photovoltaic devices. Particularly, this method and apparatus can be used in bulk-hetero-junction of mixed coating of P-type and N-type semiconductors.

The electron acceptor further comprises a nano-scale electron acceptor material, and a meso-scale mixture of electron donor/acceptor material. The multi-substituted fullerene derivative further comprises a single fullerene structure and a multi-substituted derivative connected to the single fullerene structure.

In the conventional knowledge, the large-scale segregation and corresponding degradation of power efficiency are cause mainly by the nano-scale acceptor material.

It does not need any surface catalytic processing and extra voltage. Instead, it can carry out the nickel deposition on the specific surface with a high nickel plating rate, a simple process and a low production cost.
