固定式太阳能聚光器可以与建筑立面和屋顶集成，减少太阳能电池的面积，获得更高的温度热源，特别适合冬季建筑应用。为满足应用要求，设计研究了一种带气隙的固定式透镜壁复合抛物型聚光器。气隙透镜壁CPC与原透镜壁CPC的不同之处在于，它在透镜结构和反射器之间存在气隙，使内反射总量最大化，并通过减少镜面反射的光学损耗来提高光学效率。仿真和实验验证了新结构的功能，结果表明，与原有的透镜壁CPC相比，带气隙的透镜壁CPC的光学效率提高了10%以上。此外，有气隙的透镜壁CPC比普通镜面CPC的通量分布更均匀。因此，具有气隙的镜壁CPC不仅比普通镜面CPC具有更大的半接受角和更均匀的通量分布，而且比原镜壁CPC具有更高的光学效率。因此，带气隙的透镜壁CPC作为固定式聚光器，为建筑集成聚光光伏（BICPV）提供了一种现实有效的解决方案，具有良好的应用前景。
Stationary solar concentrators can be integrated with building façade and roof, which can reduce the area of solar cells and attain higher temperature heat resource, especially in winter for building application. In this paper, a stationary lens-walled compound parabolic concentrator (CPC) with air gap was designed and investigated to meet the application requirements. The lens-walled CPC with air gap differs from the original lens-walled CPC in that it has an air gap between the lens structure and the reflector that maximizes total internal reflection and improves optical efficiency by reducing the optical losses of the specular reflection. The simulation and experiment verified the function of the new structure, and the results indicated that the lens-walled CPC with air gap increases optical efficiency by more than 10% compared with the original lens-walled CPC. In addition, the flux distribution of the lens-walled CPC with air gap is more uniform than that of the common mirror CPC. Thus, the lens-walled CPC with air gap not only has a larger half acceptance angle and a more uniform flux distribution than the common mirror CPC but also operates at a higher optical efficiency than the original lens-walled CPC. Thus, the lens-walled CPC with air gap provides a realistic and valid solution to Building Integrated with Concentrating Photovoltaic (BICPV) as a stationary concentrator and has good prospects for several applications.
