针对菲涅尔透镜存在实际光学效率偏低的问题, 本文设计了一种由非球面透镜和棒锥镜组成的高效非成像聚光光学系统。在光学设计软件 Zemax的序列模式下对非球面透镜进行了优化设计, 通过最大程度地减小球差, 像面光斑的几何半径从 42 mm降到了 1.7 mm。基于此, 在 Zemax的非序列模式下, 完成了非球面透镜和棒锥镜的建模和优化, 通过蒙特卡罗光线追迹分析实现了光学效率为 87%、接收角为 0.9°的非成像聚光光学系统。最后, 基于非球面透镜阵列和棒锥镜样品, 实现了高倍聚光型光伏模组的封装与测试。测试结果表明, 该模组的光电转换效率达 30.03%, 与菲涅尔透镜构成的高倍聚光型光伏模组相比有显著提升。

Aiming at the lowoptical efficiencyof Fresnel lens, a high-efficiency non-imaging concentrated optical(NICO) system composed of an aspheric lens and a trumpet lens was designed. The aspheric lens was optimizedinsequential mode of Zemax, and the geometric radius of its image spot was reduced from 42 mm to 1.7 mm by mi-nimizing the spherical aberration. The aspheric lens and trumpet lens were modeled and optimized in non-sequential mode of Zemax, and the NICO system with 87% optical efficiency and 0.9° received angle was achieved by Monte Carlo ray tracing analysis. Finally, the packaging and testing of the high concentrated photovoltaic (HCPV) module were completed based on samples of an aspheric lens array and 48 trumpet lenses. The test results showed that the photoelectric conversion efficiency of the module reached 30.03%, which was significantly improved compared with the HCPV module composed of the Fresnel lens.
