    • A manufacturing method of a polymer solar cell is illustrated. A substrate and a first conductive layer formed thereon are provided. An organic active semiconductor material and a functional organic material, which features modifying an interface between an organic layer and electrodes, are dissolved in an organic solvent to form a blend. The blend is deposited on the first conductive layer by solution process. The organic solvent is removed, such that the functional organic material and the organic active semiconductor material exhibit phase separation so as to form an organic modified layer on the top of the organic active semiconductor layer. A second conductive layer is deposited by thermal coating on the organic modified layer. Importantly, the organic modified layer formed by spontaneous phase separation effectively modifies the interface between the organic active semiconductor layer and a second conductive layer, thereby enhancing efficiency of an organic solar cell.
    • 示出了聚合物太阳能电池的制造方法。 提供基板和形成在其上的第一导电层。 将有机层和电极之间的界面改性的有机活性半导体材料和功能性有机材料溶解在有机溶剂中以形成共混物。 通过溶液法将共混物沉积在第一导电层上。 除去有机溶剂,使得功能性有机材料和有机活性半导体材料表现出相分离,从而在有机活性半导体层的顶部上形成有机改性层。 通过热涂覆在有机改性层上沉积第二导电层。 重要的是,通过自发相分离形成的有机改性层有效地改变了有机半导体层与第二导电层之间的界面,从而提高了有机太阳能电池的效率。
