Abstract:
PURPOSE: A nickel oxide thin film and a method for manufacturing an organic solar cell using the same are provided to efficiently transmit holes from an active layer to an anode by forming a buffer layer between the active layer and an electrode to increase hole transmission performance. CONSTITUTION: A nickel oxide precursor is prepared(100). A precursor solution is made using nickel precursor powder(200). A thin film is deposited by coating the substrate with nickel oxide precursor solutions(300). Solvents are volatilized by a pre-treatment in the deposited thin film(400). A lattice structure is formed in the thin film by a post-treatment in the thin film(500).

Abstract:
A transistor having a multi-active layer is provided. The multi-active layer works as the channel of the transistor. The transistor comprises a first channel layer and a second channel layer. The first channel layer works as a main channel. The second channel layer protects the first channel layer and forms source/drain electrodes and resistance contact.
