Full-solution processed polymer solar cells are able to be quite cost efficient, which provide a recognized effective approach to realize large-scale roll-to-roll fabrication and commercial applications. Therefore, it has important research and application value for the national energy and environment. So far, there are still two bottle-neck problems in full-solution processed devices: fabricating high-quality printable metal electrodes and improving power conversion efficiency (PCE) in further step. To address these challenges, in this project, a low-cost high-quality metal printing method based on polymer assisted metal deposition (PAMD) will be utilized to fabricate light-trapping nano-structured metal electrodes for full-solution processed polymer solar cells. This research will focus on making clear how the chemical deposition condition affects the metal thin film internal structure and components, surface morphology, replication on nano-structured substrates, electrical and optical properties. On the basis of theoretical model building, simulation and device fabrication, this project aims to achieving PCE improvement in full-solution processed polymer solar cells in attribute to the light-trapping effects from printable nano-structured metal electrodes, and meanwhile studying the relative physical characteristics. This project will set remarkable foundation for the application of this printable (nano-structured) metal thin film in optical and optoelectronic devices in the future.
