Abstract: Disclosed is a method for adsorbing a dye for a dye-sensitized solar cell. The method includes: coating a paste including metal oxide nanoparticles on the upper surface of a titanium oxide thin film and calcining the coated paste to form a porous film; adding an additive to a sensitizing dye solution to promote the adsorption of the dye; and dipping the porous film in the sensitizing dye solution to adsorb the sensitizing dye onto the surface of the porous film. The sensitizing dye solution is a dispersion of the sensitizing dye in an organic solvent. Also disclosed are a working electrode prepared using the sensitizing dye solution and a dye-sensitized solar cell including the working electrode. The addition of the additive shortens the time of dye adsorption. Despite the shortened adsorption time, the dye does not undergo desorption in the long term as well as in the short term, ensuring long-term stability of the solar cell.

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.
