光伏发电是目前太阳能最佳的利用方式之一，但发电成本高。利用聚光结构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。以Lumogen F Red 305（LR305）染料作为荧光材料，将其掺杂到PMMA中，通过本体聚合法制作出尺寸为50 mm ×50 mm ×5 mm的PM M A平面荧光太阳能聚光波导，对其光学特性进行表征，同时将太阳能电池粘贴到聚光波导的输出端面，通过测试平面荧光太阳聚光波导对太阳能电池性能的影响研究了荧光太阳能聚光波导的聚光特性。“,”Photovoltaic power generation is one of the best ways to utilize solar energy ,but the cost of electricity is very high . To reduce the cost of photovoltaic power generation ,in this paper ,a type of planar luminescent solar concentrator waveguides based on Lumogen F Red 305 (LR305) dye with each size of 50 mm × 50 mm × 5 mm was proposed with radical polymerization method .The optical properties and photo‐electricity outputs of the waveguides were characterized .
