In contrast to previous Fresnel lens concentrator  this design increases the acceptance angle  improves the irradiance uniformity on the solar cell  and reduces the aspect ratio significantly. Another outstanding advantage of this concentrator is the fact that it mainly works by performing total internal reflection  reducing chromatic dependence as well as Fresnel losses. An optical efficiency more than 80% can be achieved. Moreover  in order to reduce the influence of manufacture accuracy and to increase the optical efficiency further  the central part of the bottom of the secondary lens which directly adhered to the solar cell is designed as a cone-shaped prism to collect the sunlight that doesn't reach the solar cell. 2010 SPIE.   双菱体λ/4消色差相位延迟器的设计 期刊论文  OAI收割 光子学报, 2008, 卷号: 37, 期号: 1, 页码: 136, 139 薄锋; 朱健强; 康俊; 陈刚 收藏  |  浏览/下载：1531/392  |  提交时间：2009/09/18 激光技术  椭偏法  菲涅尔反射  λ／4消色差相位延迟器  双菱体  Birhomb  Fresnel reflection  Lambda/4 achromatic phase retarder  Laser technique  Total reflection phase transformation
