Abstract: Disclosed is a moisture barrier film for an organic-inorganic hybrid photovoltaic cell which includes an ionic polymer. Also disclosed is an organic-inorganic hybrid photovoltaic cell including the moisture barrier film. The photovoltaic cell has a structure in which the moisture barrier film including an ionic polymer is formed on an absorber layer including an organic-inorganic hybrid perovskite compound. Due to this structure, the moisture barrier film effectively protects the organic-inorganic hybrid perovskite absorber layer, which is very susceptible to moisture, and other constituent layers, from moisture from the external environment so that excellent characteristics of the photovoltaic cell can be maintained for a long time. In other words, the moisture barrier film including an ionic polymer is interposed between the absorber layer and a hole transport layer or between the hole transport layer and a second electrode to enhance the physical and chemical binding therebetween.

Abstract: Disclosed are organic solar cells whose photostability is enhanced by the introduction of an intermediate layer. The organic solar cells are free from problems associated with poor photostability of conventional organic solar cells. Therefore, the organic solar cells can maintain their initial efficiency for a long time, achieving markedly improved life characteristics. In addition, the organic solar cells can be fabricated on a large scale.
