In 1991, Prof. Grätzel’s group in Swiss Federal Institute of Technology reported their breakthrough in exploring high-performance dye-sensitized nanocrystalline solar cells (Nature 1991, 353, 737), addressing potential to provide human with low cost, highly efficient and renewable green energy, and simultaneously providing a quotable reference for later research over semiconducting polymer nanocrystalline heterojunction photovoltaics and other nanocrystalline electrochemical devices, with a novel device architecture. After massive and systematic research on sensitizer design and purification, nanocrystalline film optimization and electrolyte exploration in the past years, an efficiency over 11.6% has been obtained under the AM 1.5G conditions; in the meantime, thermally stable devices exhibiting efficiencies over 10% have been fabricated with lowly volatile organic solvent electrolytes and novel bipyridyl ruthenium sensitizers; recently, eutectic ionic liquid electrolytes realized devices of an efficiency of 9.1%, together with high thermal stability. These representative achievements offered fine scientific evidence for the industrialization of the field. Some of the research focuses are on more rational designing of sensitizers, fabrication of nanocrystalline films with higher electron transport capability, and developing electrolytes that could perform even better; all these efforts are targeted at the exploration for higher energy conversion efficiencies. A second dedication is aimed at elegantly combining high efficiency and high thermal stability, which definitely relies on an in-depth understanding of interfacial charge transfer and charge transport on the microscopic scale. Besides the research interests stated above, our group still concentrates much attention on devising new device concepts and charge transport in advanced soft matter transport systems, and related fundamental physicochemical issues. All these endeavors contribute to the essential motive to develop low-cost, long-lifetime and high-performance photovoltaic technology with independent intellectual property rights.
