Description

超高倍率聚光太阳能电池装置
所属技术领域
本发明提供一种超高倍率聚光的太阳能电池装置，特别适合于单、多晶硅太阳能电池板组成的光伏发电系统，属于太阳能光伏发电领域。
背景技术
目前，由于高纯度单、多晶硅的生产技术垄断在几个国外高技术企业手中，晶体硅的价格高居不下，而太阳能光伏发电系统需要大量的单、多晶硅，因而目前太阳能发电项目大面积推广应用受阻，国内很多市场都是因为太阳能电池板的价格太贵而无法接受；同时，国内外专家们已经研究发现，晶体硅光伏电池在正常的太阳光强下使用实际上是大材小用，因为光伏电池可以承受更高的光强，发出的电流成比例增加而又不至于影响光伏电池寿命，如果通过几十倍甚至几百倍的聚光来提高光伏电池区域的光强，输出相同功率电流的光伏电池面积就能够大幅度缩小，这样一来，太阳能电池板晶体硅的使用量就能大幅度减少，太阳能电池的价格可以大幅度下降，达到用户能够接收的水平。
通过聚光提高太阳能发电的效益，国内外已经有过一些工业化尝试。比如利用菲涅尔透镜实现3～7倍的聚光，但由于透射聚光的光强均匀性较差、且特制透镜成本降低的速度赶不上高反射率的平面镜，因此国外开始尝试通过反射实现聚光，比如德国ZSW公司发明了V型聚光器实现了2倍聚光，美国的Falbel发明了四面体的聚光器实现了2.36倍聚光，以及国内专家提出的一种八面体聚光漏斗实现了4.8倍聚光等等方法；以上这些方法都只能实现10倍以内的聚光倍率，没有彻底解决高倍率聚光的难题，因此，其性能价格比并不理想，并没有达到大面积推广应用的目的。
发明内容
本发明的目的是提供一种达到400倍以上的超高倍率聚光的太阳能电池装置。
本发明的任务是通过以下方式完成的：一种超高倍率聚光太阳能电池装置，包括聚光机构、太阳能电池机构以及散热机构；聚光机构包括抛物面型底座和大量小块平面镜，聚光机构利用公知的凹面镜聚光原理，将大面积光线聚集在焦点，反射镜面用大量小平面镜一块块拼成，这些小平面镜贴在抛物面型底座内侧；太阳能电池机构由4块(或多块)小方块(如：10mm*10mm)的太阳能电池片组成，安装在一个支撑物件的4个或(多个)侧面，并使电池片与支撑物件接触紧密，让该4块(或多块)太阳能电池片正好处在聚光机构的焦点上，用以收集聚集的超强光线，支撑4个(或多块)太阳能电池片的支撑物件竖直连接到抛物面型底座正中间，并使它们接触良好，支撑物件由导热性能良好的铝合金材料(或铜合金材料)制成，并与导热性能同样良好的抛物面型底座一起构成散热机构，抛物面型底座由同样的材料制成，抛物面型底座的外侧有大量的散热片以增加散热面积。在支撑物件中心留出一个小穿孔，方便太阳能电池片引出线的走线。
本发明提供的超高倍率的聚光太阳能电池装置，巧妙的利用了太阳能电池片的支撑物件和抛物面型底座，构成一道热量传导路径，使得处在太阳光线焦点的太阳能电池片虽然接受超高倍率的聚光光线和接受非常高的热量，但是由于太阳能电池片与支撑物件接触良好，热量很快被传导到支撑物件材料上，并很快传到抛物面型底座上，然后被传到抛物面型背部的大面积散热片上，由于这部分散热面积非常大，又没有经过太阳的照射(因为本装置需要通过一个太阳自动跟踪系统的控制，使得阳光一直对聚光电池装置成直射状态)，因此聚集的大量热量就被散发出去了。只要传导接触良好，在自然冷却条件下这种结构的太阳能电池片处(焦点处)的温度理论上不超过60度。
附图说明：
图1超高倍率聚光太阳能电池投影面图；
图2超高倍率聚光太阳能电池侧面图；
下面结合附图进一步详细说明本发明之实施例。
安装在支撑物件(2)上四个(或多个)侧面的4个(或多个)太阳能电池片(1)，构成太阳能电池机构，并与支撑物件(2)接触紧密，支撑物件(2)安装在抛物面型底座(3)的正中部，抛物面型底座(3)和抛物面型底座(3)内侧安装的大量小块平面镜(6)，构成聚光机构；太阳能电池片(1)处于平面镜反射光线的焦点上；抛物面型底座(3)的外侧有大量的散热片(4)，支撑物件(2)、抛物面型底座(3)和抛物面型底座(3)外侧的散热片(4)构成散热器机构，支撑物件(2)的中部有一个小穿孔(5)，用于太阳能电池机构的引线走线，支撑物件(2)和抛物面型底座(3)采用导热性能良好的材料做成，便于快速散热。
图2的中心虚线左右两边是对称的，即左右抛物面背部都有散热片，左边出于显示形状目的，没有画出散热片；同样出于突出显示目的，太阳能电池片(1)与支撑物件(2)没有接触，它们应该是紧密接触的。
