Metal oxides are very important interface materials which are typically stable and can match with the energy band of organic materials. Metal oxides can also be capable to offer good electrical properties including carrier transport, injection and collection in organic optoelectronic devices. In this project, we will develop a series of metal oxides which simultaneously fulfill the desirable features of (1) low temperature treatment, (2) solution based processes and (3) efficient hole and electron transport properties. Realizing the metal oxides with the three features will be beneficial to the development of solution-processed thin-film organic optoelectronics. We then propose the approach of doping metallic nanoparticles to further improve the electrical properties of the metal oxide films for organic devices. Using polymer solar cell (PSC) as an example, we will utilize our low-temperature solution-based metal oxides as both the hole and electron transport layers of PSCs to investigate and demonstrate all-solution fabrication process for realizing low-cost organic devices on standard substrate with transparent electrode.
