摘要 衍射光学元件(Diffractive optical elements,DOE)具有独特的色散特性和灵活的设计自由度,将多个DOE级联用于太阳能电池聚光系统可同时实现聚焦、整形和分光谱功能、给出了设计思想和算法,并用七波长混合光作入射光进行模拟,优化后在目标面得到七个形状规则且完全分开的均匀圆斑、将此级联结构应用到太阳能聚光系统可有效提高太阳能利用效率。 Diffractive optical element (DOE) has unique dispersion characteristics and flexible design free- dom. The cascaded DOE was applied in the concentrator system of solar cell to achieve focusing, shaping
