要：高倍聚光光伏技术是将垂直入射于菲涅耳透镜上的太阳光聚焦到电池片上，通过光电转换产生电能，但实际应用时，由于跟踪器跟踪精度低、支架受风会抖动等因素存在，无法保证太阳光始终垂直入射于菲涅耳透镜。针对该问题，在菲涅耳透镜和太阳能电池之间增加一个可拆卸的倒置的去掉顶部的棱锥形二次反射镜来提高聚光光伏的接收角，给出了具体的设计实例，并应用Solidworks软件和Tracepro软件对设计实例进行了计算机光学模拟。结果证实该二次反射镜能很好地提高聚光光伏的接收角，并改善菲涅耳透镜聚焦光斑的能量均匀性。<br /> The direct fraction of sun irradiation is used to focus on Fresnel lens in High Concentrated Photovoltaic technology, electric energy is produced through photoelectric inversion. However, because of many factors in practice like the low tracking accuracy of tracker, structure vibration by winds and atmospheric scattering, the direct normal irradiation to the Fresnel lens can not be guaranteed. To solve this problem, a removable secondary mirror whose shape was a reverse cone with no top was added between the Fresnel lens and solar cells to increase the acceptance angle of the solar module. A design example was given, and analyzed by optical simulation with the software of Solidworks and Tracepro. The conclusion indicates the removable secondary mirror can increase the acceptance angle and improve the irradiance uniformity of the focus spot.<br /> 关键词：菲涅耳透镜 高倍聚光光伏 二次反射镜 光学设计<br /> Fresnel lens high concentrated photovoltaic secondary mirror optical design ;</div> <div style="height200px;"></div> </div> </div> </div> </div></div> </div> <!--autocomment filter by maxnum--> <div class="ft_wp"> <div id="ft" class=" cl"> <div id="flk" > <p> <a href="http://wpa.qq.com/msgrd?V=3&Uin=20600600&Site=光电工程师社区&Menu=yes&from=discuz" target="_blank" title="QQ"><img src="static/image/common/site_qq.jpg" alt="QQ" /></a><span class="pipe">|</span><a href="http://m.oecr.com" >手机版</a><span class="pipe">|</span><a href="http://so.oecr.com" title="站内搜索" target="_blank" >搜索</a><span class="pipe">|</span><a href="http://www.focaloptics.com" title="主办单位：武汉焦点光学技术有限公司" target="_blank" >焦点光学</a><span class="pipe">|</span><a href="http://www.oecr.com" target="_blank">光电工程师社区</a> ( <a href="http://beian.miit.gov.cn/" target="_blank">鄂ICP备17021725号-1</a> <a href="http://www.beian.gov.cn/portal/registerSystemInfo?recordcode=42011102000821" target="_blank">鄂网安备42011102000821号</a> ) <span id="tcss"></span><script type="text/javascript" src="http://tcss.qq.com/ping.js?v=1eOg" charset="utf-8"></script><script type="text/javascript" reload="1">pgvMain({"discuzParams":{"r2":"1028778","ui":0,"rt":"plugin","pn":1,"qq":"000"},"extraParams":""});</script></p> <p class="xs0"> <span id="debuginfo"> Copyright 2015 光电工程师社区 版权所有 All Rights Reserved. </span> </p> </div> <div id="ftl" > <p>申明：本站为非盈利性公益个人网站，已关闭注册功能，本站所有内容均为网络收集整理，不代表本站立场。如您对某些内容有质疑或不快，请及时联系我们处理！ </p> </div> <div id="frt" > <div class="wp"> <p class="dd01"> © 2001-2022 <a href="http://www.oecr.com" target="_blank">光电工程师社区</a> 网站备案号：<a href="https://beian.miit.gov.cn/">鄂ICP备17021725号</a> 网站公安备案号：<a href="http://www.beian.gov.cn/portal/registerSystemInfo?recordcode=42011102000821">鄂42011102000821号</a> Powered by <a href="http://www.discuz.net" target="_blank">Discuz!</a> <em>X3.2</em> </p><p class="dd02">GMT+8, 2025-12-17 03:32 </p> </div> </div></div> </div> </div> <!--bottombg结束--> <!--<div id="scrolltop"> <span hidefocus="true"><a title="返回顶部" onclick="window.scrollTo('0','0')" class="scrolltopa" ><b>返回顶部</b></a></span> </div> --> <div id="scrolltop"> <span hidefocus="true"><a title="返回顶部" onclick="window.scrollTo('0','0')" class="scrolltopa" ><b>返回顶部</b></a></span> </div> <script type="text/javascript">_attachEvent(window, 'scroll', function () { showTopLink(); });checkBlind();</script> <div id="discuz_tips" style="display:none;"></div> <script type="text/javascript"> var tipsinfo = '1028778|X3.2|0.6||0||0|7|1765913568|f3a7002d97ba5fe4238a229a19ddbcce|2'; </script> <script src="http://discuz.gtimg.cn/cloud/scripts/discuz_tips.js?v=1" type="text/javascript" charset="UTF-8"></script></body></html>
