在太阳能薄膜电池组件2固定在所述第一柔性保护膜层展开后的中部位置后，可以覆盖开窗口的柔性保护膜层3，所述开窗口柔性保护膜层的中部开有窗口，所述窗口理论上最好与太阳能薄膜电池组件2的面积大小相同，以方便太阳能薄膜电池组件2能够很好地暴露出来，以便于太阳照射其上产生电能。如果该窗口比太阳能薄膜电池组件2的面积大，会造成所述开窗口柔性保护膜层3与太阳能薄膜电池组件2有间隙，影响美观；如果窗口比太 阳能薄膜电池组件2的面积小，会造成所述开窗口柔性保护膜层3遮挡太阳能薄膜电池组件2，影响发电效率，降低发电量。其中所述开窗口柔性保护膜层3不透明，可以采用防水布，当然也可以采用ETFE，ECTFE或其他合适的材料。
在所述太阳能薄膜电池组件2和所述开窗口柔性保护膜层3之上，还设有第二柔性保护膜层32，该第二柔性保护膜层为透明柔性保护膜层，所述第二柔性保护膜层32至上而下依次包括上表层321、粘结层322；其中，所述上表层321优选为透明、防水、防刮、耐摩擦、耐候性强的材料，例如ETFE层，也可以采用ECTFE或具有透明、防水、防刮、耐摩擦、耐候性强的其它材料；所述粘结层322优选为热熔胶层，例如EVA层。所述第二柔性保护膜层的上表层采用多点凹面结构，以减少太阳光的反射，提高太阳能转换电能的效率。

针对上述实施方式，当采用了开窗口柔性保护膜层时，所述导线5位于所述开窗口柔性保护膜层与第一柔性保护膜层31之间，并穿过所述粘结层311和下表层312以连接至所述接线盒上。
如果不采用开窗口柔性保护膜层，所述导线5可以位于所述透明柔性保护膜层与第一柔性保护膜层31之间，并穿过所述粘结层311和下表层312以连接至所述接线盒上。
可选地，所述导线5优选为镀锡编织铜带。
所述电能输出装置4及LED设置，可以参考前述的实施方式。
此外，所述充电器本体1上设有用于挂接的至少一个通孔11，具体地，在本具体实施方式中，所述通孔11设置为四个，分别设置在充电器本体1的四个角上，通过通孔11的设置，用户可以方便地把本具体实施方式提供的便携式太阳能充电器挂接到用户随身携带的包上，例如背包、挎包等。当然，通过通孔11，本具体实施方式的便携式太阳能充电器还可以挂接到户外光照条件较好位置的固定装置上。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
