摘要
According to one aspect of the present invention, the invention provides a method for forming a thin film having a small-molecule bulk heterojunction that forms a percolating network. The method for forming the thin film comprises the steps of: separately putting a first small-molecule material and a second small-molecule material in a plurality of deposition crucibles of an alternate thermal evaporation chamber, wherein the alternate thermal evaporation chamber includes the plurality of the deposition crucibles, a substrate stage located at the position facing said crucibles, and a separation membrane that is extended up to said substrate stage from said evaporation crucibles and separates an area of the chamber; locating a substrate on said substrate stage of said chamber; and alternately depositing said first small-molecule material and said second small-molecule material on said substrate by rotating said substrate in a vacuum state and heating said deposition crucibles.
