Description
技术领域
本发明涉及太阳能电池技术领域，特别涉及一种晶体硅太阳能电池组件。
背景技术
太阳能电池组件，也叫太阳能电池板，是太阳能发电系统中的核心部分，也是太阳能发电系统中最重要的部分。太阳能电池是通过光电效应或者光化学效应直接把光能转化成电能的装置。太阳能电池作为绿色能源，越来越受到人们的关注。传统的太阳能电池组件的主栅采用银印制栅线，成本较高。
发明内容
本发明的目的是克服现有技术存在的缺陷，提供一种制作简便的低成本的晶体硅太阳能电池组件。
实现本发明目的的技术方案是：一种晶体硅太阳能电池组件，具有依次层叠的负极层、N型硅层、P型硅层和正极层；所述负极层的表面上设有通过网版图形印刷形成的主栅以及与主栅垂直且等间距分布的副栅；所述正极层上具有背电极和背电场；所述主栅上均布有若干圆形的小孔。
上述技术方案所述负极层为银层。
上述技术方案所述正极层为氧化铝层，正极层上具有若干通孔；所述通孔内置有银层。
上述技术方案所述负极层和N型硅层之间还设有氮化硅减反射膜层。
上述技术方案所述氮化硅减反射膜层和N型硅层之间还设有第一二氧化硅钝化膜层。
上述技术方案所述P型硅层和正极层之间还设有第二二氧化硅钝化膜层。
采用上述技术方案后，本发明具有以下积极的效果：
（1）本发明的主栅上均布有若干圆形的小孔；可以减少银浆的使用，降低了制作成本。
（2）本发明采用PECVD沉积氮化硅膜作为太阳能组件的减反射膜层,主要作用是减少光的反射，而且氮化硅膜含有大量的氢，可以很好的钝化硅中的表面悬挂键，从而提高了载流子迁移率；同时，在氮化硅膜与N型硅之间沉积二氧化硅膜，可以更有效的减少入射光在太阳能电池表面的反射损失，提高太阳能组件吸收阳光的量，并能让太阳能组件吸收来自各个角度的全部阳光光谱，从而使太阳能电站的经济效益大为改善。
（3）本发明的正极层和P型硅层之间设有第二二氧化硅钝化膜层；二氧化硅具有吸杂、钝化的作用，可以提高反射效率。
