Composition for reducing work function of metal oxide-based electron-collection buffer layer, inverted organic solar cell using the same, and preparation method of the inverted organic solar cell
The present invention relates to a composition for reducing the work function of a metal oxide electron collection layer, a reverse structure organic solar cell using the same, and a method for manufacturing the reverse structure organic solar cell, and a metal oxide electron collection layer which is a component of the reverse structure organic solar cell. By modifying the surface of the metal oxide using a neutral polymer, the work function of the metal oxide is lowered to increase the built-in potential, and by facilitating the movement/collection of charges through the formation of polymer nanodots by the neutral polymer. , the efficiency of the reverse structure organic solar cell using the polymer can be greatly improved.
