Description

太阳能面板
技术领域
本发明涉及一种太阳能面板。
背景技术
太阳能面板已成为能源领域的研究热点，其可应用于房屋等建筑、路灯照明等装置、甚至各种便携式电子装置，用于将太阳光能转化为电能。
太阳能面板是利用太阳能电池板将太阳的辐射能光子通过半导体物质转变为电能(参见“Grown junction GaAs solar cell”，C.C.Shen；Pearson，G.L.；Proceedings of the IEEE，Volume 64，Issue 3，March 1976 Page(s)：384-385)。
现有的太阳能面板一般需暴露在室外，长期以来，其集光面很容易被污染，造成光透过率降低使同样光辐射条件下光电转换效率降低，有时还会造成“热斑”效应，致命其组件损坏，而影响其正常的使用，因此通常需要人工清洁，耗费时间且有时不能及时进行清洁。
发明内容
有鉴于此，有必要提供一种具有较佳自清洁能力的太阳能面板。
一种太阳能面板，其包括：一个玻璃板、一个太阳能电池组及至少一个紫外光发光二极管。该玻璃板包括一个集光面、一个与该集光面相对的底面以及位于该集光面与该底面之间的侧面，该玻璃板的集光面设置有一个光触媒层；该太阳能电池组与该玻璃板的底面相对设置且远离该集光面；该至少一个紫外光发光二极管与该玻璃板的侧面相对设置以使其发出的紫外光通过该玻璃板的侧面照射至该光触媒层。
与现有技术相比，所述太阳能面板的集光面上的光触媒层与太阳光线中的紫外线或/及紫外光发光二极管发出的紫外光发生反应，有效的分解沉积在太阳能面板的集光面上的有机物，并且使集光面变成亲水性，把空气中的水汽或者雨滴变成一个薄层而使集光面湿润，洗掉集光面上之脏物。无论是白天还是黑夜，所述太阳能面板都能对其表面进行自清洁，可保持较高的太阳光透过率，有效的提高太阳能面板的光电转换效率，且免除人工清洁所引发的耗费时间等问题。
附图说明
图1是本发明实施例提供的太阳能面板的结构示意图。
图2是本发明实施例提供的太阳能面板上的至少一个紫外光发光二极管嵌入该玻璃板的侧视图。
具体实施方式
下面将结合附图对本发明实施方式作进一步的详细说明。
参见图1，本发明实施例提供的太阳能面板100，其包括：一个玻璃板11、一个太阳能电池组12及多个紫外光发光二极管13。
该玻璃板11包括一个集光面11a、一个与该集光面11a相对的底面11b，以及位于该集光面11a与该底面11b之间的侧面11c。该玻璃板11的集光面11a上设置有一个光触媒层14。该太阳能电池组12与该玻璃板11的底面11b相对设置。该玻璃板11优选紫外光线穿透率高的石英玻璃。该光触媒层14一般选用二氧化钛(TiO2)，二氧化钛吸收波长小于等于387nm的光线，而可见光和红外光可以完全通过二氧化钛而不被吸收，因此，该光触媒层14的设置不会影响太阳能电池的光电转换效率。一般采用物理沉积方法，如磁控式溅镀法或电子束沉积法将二氧化钛沉积在该集光面11a上，以形成一个光触媒层14。
该多个紫外光发光二极管13与该玻璃板11的侧面11c相连接，其发出的紫外光通过该玻璃板11的侧面11c入射至该玻璃板11并照射至该光触媒层14。当然，该多个紫外光发光二极管13也可以与该玻璃板11的侧面11c相对设置，或嵌入该玻璃板11内，如图2所示。该多个紫外光发光二极管13与该太阳能电池组12电连接，由该太阳能电池组12提供电能。该多个紫外光发光二极管13发出光线的波长小于等于387nm，其构成材料可为AlInGaN的Ⅲ氮化物，其主要发光层可为一种以含有In的氮化物为主的多重量子井结构。
可以理解的是，该紫外光发光二极管13不限于多个，也可以为一个，该一个紫外光发光二极管13可以与该玻璃板11的侧面11c相对，或与该玻璃板11的侧面11c相连接，或嵌入该玻璃板11内，紫外光发光二极管13数量及设置方式可视实际需要而定。
该太阳能电池组12吸收穿透该玻璃板11的集光面11a的太阳光线，将光能转换成电能并储存在该太阳能电池组12内，其中部分电能传送给该多个紫外光发光二极管13。一般该多个紫外光发光二极管13设置有一个控制开关(图未示)，在白天，使该多个紫外光发光二极管13处于关闭状态，以节约能源。该光触媒层11直接与太阳光中的紫外线发生反应，分解沉积在太阳能面板100的集光面11a上的有机物，有效的清洁有机污染物，且使该集光面11a变成亲水性，把空气中的水汽或者雨滴变成一个薄层而使该集光面11a湿润，洗掉其表集光面11a上的脏物。晚上则开启该多个紫外光发光二极管13，该多个紫外光发光二极管13发出的紫外光也能与该光触媒层11发生反应，同样能达到自动清洁该集光面11a的目的。
可以理解的是，在白天，当太阳光中的紫外光强度不足以满足该太阳能面板100进行自清洁所需的紫外光强度时，则开启该多个紫外光发光二极管13，以保证该太阳能面板100的自清洁功能正常进行。
因此该太阳能面板100无论是白天还是黑夜，都能对其表面进行自清洁，保持较高的太阳光透过率，有效的提高该太阳能面板100的光电转换效率，且免除人工清洁所引发的耗费时间等问题。
可以理解的是，本领域技术人员还可于本发明精神内做其它变化等用于本发明的设计，只要其不偏离本发明的技术效果均可。这些依据本发明精神所做的变化，都应包含在本发明所要求保护的范围之内。
