Abstract:
Novel nano thin-film photovoltaic cells based on organic semiconductor materials have been rapidly developed in recent years, and the device efficiencies of laboratory small-area cells have reached more than 20%, respectively, demonstrating extremely broad application prospects. The realization of organic thin film photovoltaic cell printing preparation and stability improvement will be the key to the organic thin film photovoltaic cell towards the application. In recent years, the research team of the author has been focusing on the research of printable e-ink materials, key thin-film printing and preparation processes, as well as the failure mechanism of thin-film photovoltaic cells. This presentation will focus on the team's research progress in large-area flexible and transparent electrodes based on silver nanowires, ZnO interfacial inks and printing preparation, as well as the failure mechanism and stability improvement solutions for organic photovoltaic cells in service.
