背景技术
目前,广泛使用的太阳能光伏板为晶硅太阳能电池板、非晶硅薄膜太阳能电池。晶硅太阳能电池板主要应用于发电系统中,具有成本低、效率高的优势。晶硅太阳能电池板表面采用金属栅线作为上部导电极,底部用金属板作为下部导电极。晶硅电池片封装在硬质的玻璃壳里,导致晶硅太阳能电池板厚重、便携性差。非晶硅薄膜太阳能电池成本高,光电转化效率低,应用较少。
发明内容
为了解决晶硅太阳能电池板厚重、便携性差的缺点,本发明提供了一种新型柔性太阳能电池板。该新型柔性太阳能电池板具有柔性,降低了太阳能电池板的光学损失,减小了太阳能电池板的接触电阻,降低了太阳能电池板的电学损失,提高了太阳能电池板的光电转化效率。
本发明采取的技术方案是:在单晶硅片表面,制备一层氧化锌导电薄膜作为太阳能电池板的上部电极,其厚度为300纳米,代替了原有的金属栅线电极;在单晶硅片采用化学腐蚀工艺,将单晶硅片表面进行绒化处理。
本发明的特征还在于:
其中,太阳能电池板的材料是单晶硅,厚度为100微米。
其中,太阳能电池板表面具有多孔纳米二氧化硅减反射膜。
其中,太阳能电池板下表面是经过了钝化处理的。
其中,太阳能电池板下部电极是由银丝构成的。
其中,太阳能电池板是采用EVA塑料封装的。
本发明的有益效果是提高了柔性太阳能电池板的发电效率,降低了生产成本。其中,透明的氧化锌导电薄膜代替了原有的栅线电机作为太阳能电池板的上部电极,降低了太阳能电池板由于栅线阴影遮挡造成的光学损失,减小了太阳能电池板栅线造成的的接触电阻;其中,单晶硅片采用化学腐蚀工艺,将单晶硅片表面制绒,降低了单晶硅片的反射率,提高单晶硅片对太阳光的吸收率;其中,太阳能电池板下表面经过了钝化处理,降低了柔性太阳能电池板的电学损失;其中,单晶硅厚度为100微米,采用EVA塑料封装,使太阳能电池板具有了柔性。

具体实施方式
下面结合附图和具体实施方式对本发明进行详细的说明。
在图1所示的实施例中,新型柔性太阳能电池板的主体为N型单晶硅(1)与P型单晶硅(2)构成的PN结,N型单晶硅(1)是使用单晶硅片在高温下采用热扩散技术制成的:70摄氏度高温下,单晶固体中原子之间会产生空位和点缺陷,液态扩散物质POCl3借助高温下单晶硅原子之间的空位和点缺陷进行热运动,由高浓度向低浓度区域扩散,经过氧化、预扩散、再分布三个过程,最终形成N型单晶硅(1)。P型单晶硅(2)是使用铝源在相同环境下制成的。
表面钝化膜(3)是在通入硅烷和氨气在1200摄氏度高温下制得的氮化硅层,其厚度约为20纳米。
上部柔性透明电极(5)是利用射频磁控溅射技术以GaN缓冲层在EVA塑料膜(7)衬底上形成的GZO导电薄膜,GZO导电薄膜主要成分为含有镓掺杂的氧化锌。
表面光陷阱(6)是在腐蚀溶液中浸泡后形成的,腐蚀溶液是氟化氢、硝酸、去离子水按照1:2:50的比例混合配制而成的,反应温度为常温。
EVA塑料膜(7)是采用层压技术压制封装而成的,EVA塑料膜(7)厚度为0.1毫米。封装厚的柔性太阳能电池板具有柔性。通过改变EVA塑料膜(7)的颜色可以改变柔性太阳能电池板的颜色。
