报告摘要: Solar power is one of the potential clean energy resources. Silicon panels based photovoltaic technology is becoming a matured power generation technology. To extend the application area and reduce the cost, R&D on new solar power technology using thin film solar cells and III-V multiple-junction solar cells become new research interests in the past years. This technical report deals with concentrated photovoltaic technology consisting of high-efficiency multi-junction solar cells, concentrating optical systems, tracker and SCADA.
Following brief introduction to CPV technology in Section I, the power rating station for CPV modules are presented in Section II. This power rating station, the first of this kind in the world is installed in our CNAS lab as well as in the production lines. Section III discusses one of the new applications of non-imaging optical systems in concentrated photovoltaic technology. Design of non-imaging optical systems with ball lens SOE solutions was discussed in detail including efficiency optimization, irradiance non-uniformity, acceptance angle, spectral matching of solar cell with sun light and chromatic aberration control and balance of optical system etc. Temperature stability of CPV modules is also characterized. Manufacturing of non-imaging optical system (SOG and SOE) is described and experimental demonstration of the non-imaging optical system with ball lens SOE solutions is presented in Section IV. Concluding remarks together with video of the first 120MW CPV power station in Golmud are finally presented in Section V.
报告人简介: Liao Tingdi received his BSc in Physics and MSc in Optics from Fujian Normal University in 1983 and 1986, respectively. From 1986 to 1993 he was a teaching assistant and lecturer at Fujian Normal University. He started his PhD courses at The University of Oxford in January 1994 after being awarded K C Wong scholarship and received his PhD degree in optoelectronics in 1996. Dr Liao joined The University of Leeds from July 1996 to July 1998 as a postdoctoral researcher. From August 1998 to December 2010 he worked as an R&D engineer and optical design consultant in Renishaw plc, along with Nortel Network plc and Omega Technology. He joined Xiamen Sanan Optoelectronics Co., Ltd. as a chief scientist in optical engineering in December 2010. Dr Liao was awarded with the honorable title of “State Specially Recruited Experts” in February 2012. 
His main research interests include lens design for imaging and non-imaging optical systems, lens design for laser beam transforming. Diffractive optics, guided wave optics and Gradient index optics are also his interests.
