Description

一种透光率可调的太阳能电池组件
技术领域：
本发明涉及一种透光率可调的太阳能电池组件。
背景技术：
现有的太阳能电池组件，其无法根据外界温度自动调整透光率。
故有必要对现有太阳能电池组件作出改进，以提供一种可以根据外界温度自动调整透光率的太阳能电池组件。
发明内容：
本发明的目的在于提供一种透光率可调的太阳能电池组件，其结构简单，可以根据外界温度自动调整透光率。
一种透光率可调的太阳能电池组件，包括电池组件背板，所述电池组件背板的外表面上由内而外依次设有第一PVB胶片层、热致变色中间膜层、第二PVB胶片层、单晶硅电池片组合层、第三PVB胶片层、以及玻璃层。
本发明可通过如下方案进行改进：
所述热致变色中间膜层在外界温度T>25℃时，其透光率在40％以下；在外界温度T<26℃时，其透光率为80％。
所述电池组件背板为透明PE板、或钢化白玻。
所述电池组件背板是厚度为3mm的透明PE板、或厚度为8mm的钢化白玻。
所述第一PVB胶片层的厚度为0.76mm，第二PVB胶片层和第三PVB胶片层的厚度为0.38mm。
所述玻璃层为压花玻璃层，其厚度为6mm。
本发明具有如下优点：1、本发明通过设置热致变色中间膜层，使得本发明可以根据外界温度自动调整透光率。2、当外界温度T>25℃时，热致变色中间膜层显浅黄色，其透光率在40％以下，温度越高，透光率越低，可以起遮阳效果；当外界温度T<26℃时，热致变色中间膜层显无色，其透光率为80％，可以起到良好采光的效果。
附图说明：
图1为本发明结构剖视图。
具体实施方式：
如图所示，一种透光率可调的太阳能电池组件，包括电池组件背板1，所述电池组件背板1的外表面上由内而外依次设有第一PVB胶片层2、热致变色中间膜层3、第二PVB胶片层4、单晶硅电池片组合层5、第三PVB胶片层6、以及玻璃层7。
进一步地，所述热致变色中间膜层3在外界温度T>25℃时，显浅黄色，其透光率在40％以下，温度越高，透光率越低，可以起遮阳效果；在外界温度T<26℃时，显无色，其透光率为80％，可以起到良好采光的效果。
再进一步地，所述电池组件背板1为透明PE板、或钢化白玻。
更进一步地，所述电池组件背板1是厚度为3mm的透明PE板、或厚度为8mm的钢化白玻。
又进一步地，所述第一PVB胶片层2的厚度为0.76mm，第二PVB胶片层4和第三PVB胶片层6的厚度为0.38mm。
具体地，所述玻璃层7为压花玻璃层，其厚度为6mm。
本发明通过设置热致变色中间膜层，使得本发明可以根据外界温度自动调整透光率。
以上所述仅为本发明的较佳实施例，并非用来限定本发明实施的范围，凡依本发明专利范围所做的同等变化与修饰，皆落入本发明专利涵盖的范围。
