报告内容摘要：

We will discuss our approaches toward room-temperature solution process for forming various devices. Regarding the room-temperature processed metal-oxide based carrier transport layer, we demonstrate their good electron and hole transport properties for all solution-processed organic/inorganic optoelectronics such as organic solar cells (OSCs), perovskite solar cells, dye sensitized solar cells, organic light emitting diodes, etc which can favor the efficient transport of carriers between the photoactive layer and electrode as well as high optical transparency. With the incorporation of metal nanoparticles, the electrical and optical properties can be enhanced. In addition, we have developed some room-temperature processed Ag nano-network which can serve as transparent flexible electrodes.
