| 报告介绍 | Abstract:
While charge transport/transfer, both on the molecular and on the bulk level, are presently fairly well understood, their characterization on the mesoscopic scale is still inadequate. These nanoscale charge transport/transfer processes, however, are important to both the frontier of fundamental science and applications to efficient energy conversion and storage devices, such as photovoltaics, photolysis, fuel cells, batteries, electroluminescent and electrochromic displays, etc. With dye-sensitized solar cells as the research platform, our work focuses on the fundamental studies of charge transport in nanostructured systems, such as electron/hole propagation in mesoscopic semiconductor films/interfaces, ion transport in ionic mesoscopic systems/boundaries, and their applications for efficient photovoltaic devices, and advanced energy storage devices, etc. This talk summarizes our recent progress in the fundamental understanding of charge separation and charge collection — the two crucial, efficiency-determining processes, as relevant to DSCs. In addition, I will highlight a conceptually new and implementable solution — Redox Flow Lithium-ion Battery (RFLB), to address the critical challenges confronted by the state-of-the-art power sources.
