具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能解释为对本申请的限制。
实施例一
本申请实施例一提供了一种薄膜双玻光伏组件，如图1所示，图1为本申请实施例一提供的薄膜双玻光伏组件的结构简图。薄膜双玻光伏组件包括背面玻璃1、前板玻璃2和薄膜电池组3。其中，背面玻璃1和前板玻 璃2之间通过隔条6(图1中未显示，可参照图2)形成中空腔体4，薄膜电池组3设置在中空腔体4中。参照图5和图6，该隔条6上设置有金属线7，金属线7的走向与隔条6的走向一致。金属线7可以为直径是0.5～1.5mm的钢线。该金属线7的设置作为背面玻璃1和前板玻璃2之间的间隔，进一步保护中空腔体4内的薄膜电池组3，避免薄膜电池组3受到过度挤压。
本申请实施例一提供的薄膜双玻光伏组件通过将薄膜电池组设置在背面玻璃和前板玻璃之间形成的中空腔体中，使薄膜电池组不会被背面玻璃和前板玻璃所挤压，从而避免了背面玻璃和前板玻璃的热胀冷缩引起的拉伸损坏，提高了薄膜电池组的寿命。同时，通过在隔条中设置金属线能够进一步将背面玻璃和前板玻璃隔离开，进而保证中空腔体内部的薄膜电池组不被损坏。
优选的是，该薄膜双玻光伏组件还包括支撑球5，支撑球5设置在中空腔体4中。
可以理解的是，支撑球5的作用是将背面玻璃1和前板玻璃2进一步支撑隔开，其材质和尺寸可以根据实际需要而进行设定。本实施例中，支撑球5为直径为2～4mm、材质为POE或EVA的交联型或热固型微球型胶粒，在进行层压时，支撑球5受热固化在背面玻璃1上。
隔条6可以使用现有技术中的普通胶条，优选的是，本实施例中隔条6为丁基胶条，粘接在背面玻璃1上。
金属线7可以设置在隔条6上，也可以设置在隔条6的内部，本实施例中，隔条6采用丁基胶条，在涂抹丁基胶条且丁基胶条没有凝固时，布置金属线7，当丁基胶条凝固后，金属线7即被包覆形成在丁基胶条的内部。
图2为本申请实施例一提供的薄膜双玻光伏组件隐去前板玻璃后的结构示意图，图3为图2中的A处放大图，图4为单个薄膜电池的结构示意图。如图2至图4所示，本实施例中的薄膜双玻光伏组件共包括三个薄膜电池组3，每个薄膜电池组3由多片独立的薄膜电池叠压形成。参照图4，单个薄膜电池上的导电丝31从电池本体上延伸出来，与另一个薄膜电池叠 压，参照图3，这样，多个薄膜电池串联在一起，形成一个薄膜电池组3。
图7为图5中的C处放大图，如图5和图7所示，考虑到后期制作中要对中空腔体4进行抽真空和注入氮气的操作，还进一步设置有中空管8，中空管8的中心轴线与隔条6的走向不平行，且中空管8的两端端口露出于隔条6的两侧，使中空管8的一端端口位于中空腔体4内，另一端端口位于外部。在中空管8的预埋过程中，保证中空管8的中心轴线与隔条6的走向不平行，才能使中空管8的两端均从隔条6两侧伸出，实际操作中，可以设置中空管8与隔条6的走向相垂直，同时，中空管8横跨隔条6处不跨越金属线7。在具体操作中，可以设置金属线7为断开状态，使中空管8从金属线7断开的位置穿过，如图7所示，从而避免中空管8与金属线7发生干涉磨损，进而导致漏气等现象的发生。为了保证中空管8的强度，可以设置中空管8为内径是2mm，长度是30mm的聚乙烯管。
图8为本申请实施例一提供的薄膜双玻光伏组件的背视图，在上述实施例的基础上，该光伏组件还包括汇流条9和接线盒10，在薄膜电池组3的背光面与汇流条9之间设置有绝缘封装膜，且汇流条9的一端与一组薄膜电池组3可导通地相连接，以将该组薄膜电池组3的电流汇集，另一端从中空腔体4中穿出后，与接线盒10相连接。
汇流条9通过出口从中空腔体4中穿出，穿出的位置可以是在背面玻璃1上，根据实际需要，可以在背面玻璃1的中间位置，也可以在其他位置；汇流条9穿出的位置也可以在背面玻璃1与前板玻璃2之间。相应地，接线盒10也可以根据汇流条9穿出的位置设置在背面玻璃1上，或者设置在背面玻璃1与前板玻璃2之间。
实施例二

步骤S100、平放前板玻璃2，在前板玻璃2朝上的一面的四周设置隔条6。
该隔条6可以是现有技术中的普通胶条，也可以是本实施例采用的丁基胶条，在前板玻璃2四周打一定量的丁基胶，作为前板玻璃2和背面玻 璃1之间的间隔。
步骤S200、将薄膜电池组3放置在前板玻璃2上，并保持薄膜电池组3的受光面朝向前板玻璃2。
根据实际需要，可以将薄膜电池组3放置在前板玻璃2的中央。
步骤S300、在薄膜电池组3的上方盖上背面玻璃1。
步骤S400、通过层压机进行层压，形成薄膜双玻光伏组件。
该步骤中，层压工艺与现有技术中的层压工艺相同，在此不再赘述。优选的是，在步骤S400之后，再进行抽真空操作操作，即该制作方法还包括以下步骤：
步骤S500、对前板玻璃2和背面玻璃1之间的中空腔体4进行抽真空操作。
在该步骤S500之后，还优选地包括注氮气操作，即该制作方法还包括以下步骤：
步骤S600、向中空腔体4内注入氮气。使薄膜双玻光伏组件在氮气的气氛下进行冷却。
将薄膜双玻光伏组件移出层压机之后，再对通入氮气的聚乙烯管裸露在外的一端进行热熔熔封，从而保证中空腔体4内部的密封状态。
优选的是，在步骤S200之后，且步骤S300之前，该制作方法还包括：步骤S210、在薄膜电池组3的间隙处布置多个支撑球5。
该支撑球5可以是直径为2～4mm、材质为POE或EVA的交联型或热固型微球型胶粒。将薄膜电池组3布设在前板玻璃2上之后，在薄膜电池组3之间的间隙处均匀撒上上述胶粒，该胶粒在层压时软化，并与前板玻璃2和背面玻璃1接触，起到对薄膜电池组3定位和限位作用。
实施例三
本申请实施例三提供了一种薄膜双玻光伏组件的制作方法，包括以下步骤：
薄膜电池组3的制作过程，包括以下步骤：
步骤S01、将多个薄膜电池进行串联叠层。
步骤S02、在层叠后的多个薄膜电池的背光面设置绝缘封装膜。

工业实用性
