Abstract:
Optimal utilization of solar energy is a promising solution to the energy and pollution problems.As one of candidates of the next generation solar cells, mesoscopic solarcells(MSC)offer a wide application prospect due to the advantages of abundant raw materials, simple fabrication process, high power conversion efficiency and so on. Han group developed a critical method to synthesis all-solid-state mesoscopic solar cells, they fabricated a perovskite solar cell that uses a double layer of mesoporous TiO2 and ZrO2 as a scaffold infiltrated with perovskite and does not require a hole-conducting layer. The cell achieved a certified power conversion efficiency of 12.8% and was stable for >1000 hours in ambient air under full sunlight.
Prof. Hong-wei Han:
Hong-wei Han, Professor of Huazhong University of Science and Technology.
Prof. Han obtained a BSc in Chemistry in 2000 and his Ph.d. in Physics in 2005 from the Wuhan University . He then worked as a post-doc in Monash University, Canada from 2006-2008. He is working in Wuhan National Laboratory for Optoelectronics, Huazhong University of Science and Technology as a professor in Chemistry.
He has been focusing on dye-sensitized solar cells, especially all-solid-state mesoscopic solar cells from 2000. He has published over 70 papers in international journals like Science, Energy Environ. Sci., J. Am. Chem. Soc. and Adv. Funct. Mater. Sci. His work was published in Science as “A hole-conductor free, fully printable mesoscopic perovskite solar cell with high stability.” The new solar cell materials had caught a lot of attention, as Professor Michael Grätzel, inventor of dye-sensitized solar cells, complimented the work as a breakthrough progress. The work also had been broadcast through medias. Associated press reported that the work is critical for the future solar cell development.
