具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明的一部分实施例，而不是全部的实施例。
基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明，本发明实施例中所有方向性指示(诸如上、下、左、右、前、后、内、外，中心……)仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
在本发明中，除非另有明确的规定和限定，术语“连接”、“固定”等应做广义理解，例如，“固定”可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
另外，本发明各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本发明要求的保护范围之内。。
现提供以下实施例：
实施例一：
如图1所述的一体层压式太阳能板的分层结构示意图，包括，从上到下依次设置的ETFE层1、透明PET层2、硅片3、PCB板层4以及布料层5；在所述 ETFE层1与所述透明PET层2之间提前敷设有第一EVA胶层6、所述透明PET 层2与所述硅片3之间提前敷设有第二EVA胶层7、所述硅片3与所述PCB板层4之间都提前敷设有第三EVA胶层8，所述PCB板层4与所述布料层5之间提前敷设有第四EVA胶层9、通过层压机使第一EVA胶层6、第二EVA胶层7、第三EVA胶层8、第四EVA胶层9加热融化，使所述ETFE层1、所述透明PET 层2、所述硅片3、所述PCB板层4以及布料层5层压为一体。
作为优选方案，所述硅片3设置有多个，各个硅片3之间通过导线相互串联。
所述透明PET层2(即涤纶树脂)，有良好的力学性能，冲击强度是其他薄膜的3～5倍，耐折性好；耐油、耐脂肪、耐稀酸、稀碱，耐大多数溶剂；透明度高；本实施例的太阳能板主要利用PET材料的高透明度(即高透光率)，从而保证硅片3的收光效率。
所述硅片3优选为单晶硅太阳电池片；其最大功率为(Rated Max Power)3.3W ±5％(W)；转换效率(Module Efficiency)为21％±2％；单片硅片的工作电压为0.55 (V)，总电压为17.6(V)；填充因子为78(％)；工作电流为5.83(A)；短路电流为6.24(A)。
作为优选方案，所述ETFE层1的厚度为0.1～0.6mm之间，ETFE(即乙烯- 四氟乙烯共聚物)，ETFE是最强韧的氟塑料，它在保持了PTFE良好的耐热、耐化学性能和电绝缘性能的同时，耐辐射和机械性能有很大程度的改善，拉伸强度可达到50MPa，接近聚四氟乙烯的2倍；本实施例中采用此种材料作为太阳能板的表层，提升了太阳能板表层的绝缘性，防止硅片转换时漏电；
作为优选方案，所述硅片3的厚度为0.1～0.3mm之间。
实施例二：
请参阅图2，本实施例还提供一体层压式太阳能板的安装结构；包括折叠板 1以及支撑板2，所述折叠板1设置有两组，相邻两所述折叠板1之间柔性连接，在日常不使用时可将相邻两所述折叠板1对折，这使得太阳能板体积小，方便携带；所述支撑板2与所述折叠板1的一端转动连接，支撑板2与折叠板1的另一端通过柔性绳3连接；通过展开所述支撑板2，将支撑板2和折叠板1平放在地板上，使设置有硅片的一面正对着阳光，保证了最大的吸收光能的效率；当柔性绳3绷紧时，太阳能的展开角度最大。
所述太阳能板还包括矩阵排列在所述折叠板1上的多组硅片11以及充电接口(图未示)，所述充电接口用于连接可充电设备后给可充电设备充电；
其中，可充电设备包括但不限于平板、手机、笔记本电脑、智能手表等。
以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
