英文摘要： The potential advantages of doctor-blading technology for fabrication of large-area flexible polymer solar cell panels attract great attention in both the academic and industrial fields. However, this technology has not been well developed. In this application, by using the materials, such as the organic solvent-soluble polymers, water-/alcohol-soluble polymers, metal oxides and so on, we will study the rheological properties of their solutions, solvent evaporation in the process of their films and the polarity of the film surface. We focus on solving the drawback of doctor-blading process of ultra-thin films, which includes the variation of film thickness and residual pinhole in films. We also try to avoid dissolving the under layers during the process of other layers. The aim of this work is to obtain high-quality films via mature doctor-blading process and construct large-area flexible solar panels, which will be supported by theory of physics and process engineering developed in this project. Moreover, as the solar panel is flexible we can use folded structure to fully utilize the solar energy and reduce the duty cycle. At the same time, we focus on studying the aging and restoring mechanism of the large-area flexible solar panels. In short, technology breakthroughs in the preparation of large-area flexibl
