报告简介:
Wihle high temperature evaporation and sputtering are commonly used for forming films of optoelectronic devices, 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. The interesting features of the novel carrier extraction layers are low temperature, solution process and water free for high performance optoelectronics such as OSCs with power conversion efficiency (PCE) of 10.5%. In addition, we have developed some room-temperature processed Ag nano-network which can serve as transparent flexible electrodes. With the knowledge of solution processed organic and inorganic materials, we also propose different low/room temperature approaches for highly stable and efficient perovskites in solar cells, LEDs and photodetectors in which the solar cells show no hysteresis and most recent PCE of 21.5%.
