The present invention provides a polymer, a method for preparing the same, and a solar cell comprising the polymer having a structure represented by Formula I,
the polymer has excellent interface-modified property, water resistance and/or excellent electron-transporting property, and thus can be effectively used to prepare solar cells. The polymer not only can significantly improve the hydrophobic property of the thin film surface of the solar cell, thereby protecting the intermediate active layer of the cell from moisture in the air so as to improve the lifetime of the cell device, but also can be used for large-area processing to prepare a flexible cell device.
本发明提供了一种聚合物、一种制备该聚合物的方法以及一种包含该聚合物的太阳能电池,该聚合物具有式 I 所表示的结构、
该聚合物具有优异的界面修饰性能、耐水性和/或优异的电子传输性能,因此可有效地用于制备太阳能电池。该聚合物不仅能显著改善太阳能电池薄膜表面的疏水性,从而保护电池的中间活性层不受空气中湿气的影响,从而提高电池装置的使用寿命,还可用于大面积加工,制备柔性电池装置。
