【摘要】 通过聚光波导提高光的转换和收集效率,是提高太阳能电池效率、减少电池用量、降低光伏发电系统成本的重要途径。利用PMMA作为波导基质材料,Rhodamine 6G(罗丹明6G)作为荧光染料,通过涂覆方法,在表面积为50mm×50mm、厚度为5mm的洁净PMMA衬底上制备出了荧光层厚度约为32μm的平面波导型聚光器,并研究了荧光染料的掺杂浓度对其聚光比和光伏性能的影响。结果表明,当掺杂浓度为0.250%时,聚光器的聚光比和器件的光伏性能达到了最优,分别为0.45%和0.49%。更多还原

【Abstract】 Photovoltaic power generation is one of the most efficient ways to utilize solar energy.In this paper,a type of planar waveguide-based luminescent solar concentrator with a surface area of 50 mm×50 mm and a height of 5 mm is fabricated by coating a layer of Rhodamine 6 G-doped PMMA on a clean PMMA substrate.The thickness of the Rhodamine 6 G-doped PMMA layer is 32 m.The influence of the concentration of Rhodamine 6 Gon the concentration ratio and photovoltaic properties has also been investigated.The results have shown that the concentration ratio and the photovoltaic properties reach 0.45 and 0.49% ,respectively when the concentration of of Rhodamine 6 Gis 0.250% .更多还原
