聚光光伏技术可以提高太阳能电池的转换效率和降低光伏系统的发电成本，在太阳能开发和利用中占有重要的地位，对其进行的研究和探索也是光伏领域中的一个热门课题。荧光太阳能聚光器（LuminescentSolarConcentrator，LSC）作为一种新的聚光形式虽然诞生较晚，但因其相对于传统聚光方式具有独特的优势，正在吸引着越来越多的科技工作者投入到这一领域的研究中。 自从LSC诞生到现在的三十多年来，在荧光材料、基底材质和器件结构等方面都取得了一定的进展。目前对LSC的研究还主要局限于荧光染料的研究上面，对器件聚光模型的改进则鲜有进一步的报道。针对这一现状，本论文以LSC聚光模型为基础，将光栅衍...As the concentrating photovoltaic (CPV) technology can improve the efficiency of the solar cells and reduce the cost of the PV systems, it is quite important for the development and exploitation of solar energy and also one of the hot topics in the field of photovoltaic.

Although Luminescent Solar Concentrator (LSC) emerges later as a new form of CPV, it is attracting more and more attention of scient ists for its unique advantages over the traditional concentrator.During more than 30 years since the birth of LSC, great achievements have been made in research on fluorescent materials, base materials, device structure, etc. However, the present studies on LSC mainly focus on fluorescent dyes and those on concentrating model are quite rare, which still need further exploration. Consequently,on the basis of LSC, this thesis applies the grating to CPV and produces a grating-based concentrator, the performance of which is also simulated and tested.Research of this thesis is mainly composed of three parts1) A physical model of CPV is built theoretically. By introducing how it operatesand inferring the relationship between performance parameters and structure parameters of the device, the concentrating principle and model are elaborated.2) Simulation experiments are made about the model by making use of the diffraction grating analysis program GSolver and ray tracing program Tracepro, which mainly includes two parts: according to the computation and analysis of the relationship between diffraction efficiency (both of the first order diffraction efficiency of transmission and diffraction efficiency of reflection) and the parameters of the grating, the appropriate grating parameters are selected to generate grating surface data; then the model is built and simulation experiment is also carried out inTracepro. The result shows that sinusoidal grating and rectangular gratingconcentrators both exhibit a wide angle of acceptance and good energy uniformity on the exit plane, with the collection efficiency of 4.4% and 9.7% respectively. If they are designed into multi- layer structures, the spectral range can be extended efficiently 厦门大学博硕士论文摘要库AbstractIVand radiation flux of the exit plane could also be improved.3) To verify the reliability of these two programs’ cooperation, a grating-based concentrator is made and its performance is also tested. The data obtained in this way is compared with those got from the simulation experiment, which proves that these two programs’ cooperation is accurate and reliable.Keywords: Photovoltaic; Luminescent
