技术领域
本发明属于太阳能电池领域，具体涉及一种可调节透光率的双面光伏组件。
背景技术
近年，随着光伏技术的不断革新，对光伏组件的需求不仅仅是与组件性能、功率相关，还与组件的适应性及美观性相关。目前双玻光伏组件较常规组件更加具备美观性，双玻光伏组件也能够与现代建筑相结合，如何更加与现代建筑完美结合以及增加透光率的随机可调节性，增加双玻光伏组件的美观性是业内争相研究的热点之一。目前业内双玻组件及BIPV组件，在透光率调节方面，通过设计组件电池片数量，在组件设计初期，确定组件透光率，而无法在组件使用过程中实现实时的透光率可调性。
发明内容
针对上述技术问题，本发明旨在提供一种可调节透光率的双面光伏组件。
为达到上述目的，本发明采用的技术方案如下：
一种可调节透光率的双面光伏组件，包括自上至下设置的前板玻璃、第一封装胶膜、电池片层及背板玻璃，所述电池片层包括多个双面太阳能电池片，所述双面光伏组件还包括设置于所述电池片层和所述背板玻璃之间的透明绝缘膜和电致发光胶膜、用于为所述电致发光胶膜供电的电源，所述透明绝缘膜设置于所述电致发光胶膜和所述电池片层之间以将二者隔离，所述双面光伏组件还包括用于调节所述电源为所述电致发光胶膜提供的电流的大小的调节机构。
进一步地，所述调节机构包括相互配合的遥控发射器及遥控接收器。
更进一步地，所述遥控接收器集成在所述电源上。
进一步地，所述透明绝缘膜为透明PET膜。
进一步地，所述电致发光胶膜为图形化的膜。
进一步地，所述电致发光胶膜的材料为有机电致发光材料。
进一步地，所述电致发光胶膜的厚度为0.4-1mm。
进一步地，所述透明绝缘膜的厚度为30-120μm。
进一步地，所述双面光伏组件为双玻光伏组件或BIPV组件。
本发明采用以上方案，相比现有技术具有如下优点：
本发明的双面光伏组件，通过采用电致发光胶膜及透明绝缘膜，实现组件透光率可调及图案可调，一方面可以方便地调节透光率，另一方面，将艺术美学与光伏组件有效的结合，使得光伏组件更加能被客户接收，进一步扩展组件的应用范围。
附图说明
为了更清楚地说明本发明的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为根据本发明的一种双面光伏组件的示意图。
其中，1、前板玻璃；2、封装胶膜；3、电池片层；30、双面太阳能电池片；4、透明绝缘膜；5、电致发光胶膜；6、背板玻璃；7、电源；70、导线。
具体实施方式
下面结合附图对本发明的较佳实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域的技术人员理解。在此需要说明的是，对于这些实施方式的说明用于帮助理解本发明，但并不构成对本发明的限定。此外，下面所描述的本发明各个实施方式中所涉及到的技术特征只要彼此之间未构成冲突就可以互相结合。
本实施例提供根据本发明的一种双面光伏组件，其具体是一种双面双玻光伏组件或一种BIPV组件，且背面透光率可调。具体如图1所示一种可调节透光率的BIPV组件，包括自上至下设置的前板玻璃1、封装胶膜2、电池片层3及背板玻璃6，电池片层3包括多个双面太阳能电池片30。该双面光伏组件还包括设置于电池片层3和背板玻璃6之间的透明绝缘膜4和电致发光胶膜5、用于为电致发光胶膜5供电的电源7，透明绝缘膜4设置于电致发光胶膜5和电池片层3之间以将二者隔离，电致发光胶膜5则位于透明绝缘膜4和背板玻璃6之间。该双面光伏组件进一步包括用于调节电源7为电致发光胶膜5提供的电流的大小的调节机构，通过调节电源7为电致发光胶膜5所供的电流的大小，实现对电致发光胶膜5的透光率进行调节的目的。
透明绝缘膜4为透明PET膜，厚度为30-120μm，作为电池层与电致发光胶膜5之间的绝缘层，在电致发光胶膜5通电发光时，避免对电池片30产生影响。确保电池片30与电致发光胶膜5之间不导通，确保组件的可靠性。
电致发光胶膜5为图形化的膜，电致发光胶膜5的材料为有机电致发光材料，电致发光胶膜5的厚度为0.4-1mm。引入电致发光胶膜5，可实现胶膜颜色和透光率可调。可通过控制电致发光胶膜5电流的大小，实现对胶膜的透光率的控制。此外，可通过设计电致发光胶膜5的图形来控制组件背面的图形。还需要说明的是：本发明的电致发光胶膜5可以完全覆盖电池层的背面，也可根据用户对组件背面外观的要求而设计为特定的图案，电致发光胶膜5所呈现的图案为用于满足用户外观要求；而透光率的调节则通过控制电源7电流大小来实现。
电源7通过导线70和电致发光胶膜5电连接。调节机构具体包括由相互配合的无线遥控发射器及无线遥控接收器构成的无线遥控系统。其中，遥控接收器集成在电源7上，通过遥控发射器接收用户的指令并发送至遥控接收器，遥控接收器根据用于指令来相应调节电源7的电流大小，实现远程控制。
本发明的双面光伏组件，通过采用电致发光胶膜5及透明PET膜，实现组件透光率可调及图案可调，将艺术美学与光伏组件有效的结合。使得光伏组件更加能被客户接收。进一步扩展组件的应用范围。
上述实施例只为说明本发明的技术构思及特点，是一种优选的实施例，其目的在于熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限定本发明的保护范围。凡根据本发明的原理所作的等效变换或修饰，都应涵盖在本发明的保护范围之内。
