具体实施方式
下面描述本公开的实施例，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。
本实施例提供了一种太阳能电池板，该太阳能电池板可以用于单车。在一实施例中，该太阳能电池板可以设置在单车的车篮内或者挡泥板上等。该太阳能电池板为单车上的用电设备供电，用电设备可以包括：智能车锁等。该单车可以为共享单车但不限于为共享单车。
如图1所示，该太阳能电池板包括电极输出汇流条100和多个并联在输出汇流条100的电池芯片组，电池芯片组由多个串联的电池芯片串1组成，图1中以加粗实线框示意出一个电池芯片组中的一个电池芯片串1(图1实施例中共包括三个电池芯片组a、b和c，且电池芯片组a包含两个电池芯片串a1和a2，电池芯片组b包含两个电池芯片串b1和b2，电池芯片组c包含两个电池芯片串c1和c2)，从结构合理的角度，每个电池芯片组内的电池芯片串1的数量可以相同；并且，该电池芯片串1是由多个电池芯片单元2串联而成，同样地考虑到电池板的合理布局，每个电池芯片串1内的电池芯片单元2的数量可以相同，且每个电池芯片单元2的面积也可以相同，前述电池芯片单元2的数量和面积可根据共享单车的车篮尺寸、负载功率等情况进行增减。接续上文，本实施例提供的太阳能电池板设置为同一所述电池芯片组内的多个电池芯片串间隔排布，一个电池芯片组内的多个电池芯片串1，与另一个电池芯片组内的多个电池芯片串1彼此交错设置，以使同一电池芯片组内的多个电池芯片串1之间不接触，也即是同一电池芯片组内的多个电池芯片串1间隔排布。在一实施例中，相邻的所述电池芯片组内的所述电池芯片串交错设置。如图1所示，电池芯片组a和b相邻，电池芯片组a内的电池芯片串a1和a2与电池芯片组b内的电池芯片串b1和b2彼此交错设置，使得电池芯片组a内的电池芯片串a1和a2间隔排布，电池芯片组b内的电 池芯片串b1和b2间隔排布，同样地，电池芯片组b和c相邻，电池芯片组b内的电池芯片串b1和b2与电池芯片组c内的电池芯片串c1和c2彼此交错设置，使得电池芯片组c内的电池芯片串c1和c2也是间隔排布。
图2为本实施例提供的太阳能电池板的等效示意图。如图2所示，虚线框分别表示电池芯片组a、b和c，电池芯片组a包含两个串联的电池芯片串a1和a2，电池芯片组b包含两个串联的电池芯片串b1和b2，电池芯片组c包含两个串联的电池芯片串c1和c2。电池芯片组a、b和c并联在输出汇流条100之间。在一实施例中，电池芯片单元2的电流大小取决于电池芯片单元2的宽度，如前述实施例所述，本公开采用多级细化的电池芯片结构，也即是尽量缩小单个电池芯片单元2的尺寸，以减小每个电池芯片单元2的发电电流，也即是减小局部区域内遮挡物对于电池板整体效能的影响，再结合前述将同一电池芯片组内的电池芯片串分隔而设的结构，使一电池芯片组内的多个电池芯片串1分开设置，以减弱甚至消除因局部区域遮挡造成的光斑效应，以及因局部区域遮挡致使整个电池芯片组乃至整个太阳能电池板的吸收转化率不良的问题。在此基础上，多个电池芯片单元2之间采用串联方式，以及多个电池芯片串1之间采用串联方式，同时，多个电池芯片组之间采用并联方式，以使太阳能电池板从整体上可灵活增减电压及电流。
在一实施例中，该电池芯片单元2的排布方式可以呈多行或多列形式，例如图1中所示的多列排布，如图1所见，多个电池芯片单元2紧密靠近，以能够充分利用空间，并且位于相同列或者相同行(对于行排布的说明，可参考列排布方式)的两个相邻电池芯片单元2的电极之间可以采用搭接或者焊接方式进行电气连接，由于在制作太阳能电池板时，会在芯片表面层压至少一层胶膜，因而足以保证电池芯片单元2之间的电气连接稳定性。
而对于处在不同列并且相互串联的两个电池芯片单元2的电极之间，则可以采用导电装置3相连，例如通过金属汇流条或者引线等方式电连接；在一实施例中，位于不同列并且相邻不串联的电池芯片单元2之间，为了保证 电气安全，可以设置电气隔离装置，在实际操作中，例如可以考虑采用绝缘涂层、绝缘胶、绝缘隔片或者绝缘隔条等。
在一实施例中，太阳能电池板包括晶硅太阳能电池板和薄膜太阳能电池板。晶硅太阳能电池板的设备成本相对较低，光电转换效率较高，在室外阳光下发电比较适宜；薄膜太阳能电池板，设备成本相对较高，光电转化效率相对晶硅电池板低，但弱光效应较好，在普通灯光下也能发电。
相关技术的太阳能电池板在使用时会被物体遮挡住，被遮挡的这部分太阳能电池板将不再产生电流，并被当作负载，从而消耗其他太阳能电池板所产生的电量，同时，阴影部分的太阳能电池板会发热，这种现象被称为“热斑效应”。“热斑效应”严重时会损坏太阳能电池板，导致太阳能电池板无法正常工作。
本实施例提供的太阳能电池板可以实现并联稳压，保证太阳能电池板在被部分遮挡时仍能正常给蓄电池充电，且充电电流不被降低，即在在有遮挡的情况下，本实施例提供的太阳能电池板能够保持电压不变，可继续给设备充电；同时由于并联增加电流，在无遮挡时，本实施例提供的太阳能电池板可以实现电流最大化。
工业实用性
本公开提供的太阳能电池板，将较大尺寸的太阳能电池板拆分成多个并联的电池芯片组，并且每个电池芯片组包括了由多个电池芯片单元串接而成的多个串联的电池芯片串，同时每个芯片组内的电池芯片串交错而设，使同组内的电池芯片串之间处于不接触状态，相较于同等面积的太阳能电池板，多级细化的电池芯片结构可以减小每个电池芯片单元的发电电流，再结合同组芯片分隔而设，从而可以减弱甚至消除因局部区域遮挡造成的光斑效应，以及因局部区域遮挡致使太阳能电池板整体吸收转化率下降的缺陷。
