现有的正四棱锥绒面结构可以降低硅片表面的反射率，但还需要进一步优化绒面结构，以便进一步降低硅片表面的反射率。
 技术解决方案
为了进一步降低硅片表面的反射率，本发明提供一种太阳能电池片，其正面设有棱锥绒面结构；所述棱锥为四棱锥，包括底面和四个侧面；沿棱锥侧周周向，该四个侧面依次为：第一侧面、第二侧面、第三侧面以及第四侧面；所述第一侧面与底面的夹角为55～90度，第二侧面、第三侧面、第四侧面与底面的夹角都为锐角；且电池片上各棱锥的第一侧面朝向相同。
优选的，所述底面为长方形或正方形；所述第二侧面与底面的夹角，等于第四侧面与底面的夹角。
在电池片放置状态相同、且太阳光入射角度相同的情况下，本发明棱锥绒面结构对太阳光的反射次数可多于现有正四棱锥绒面结构对太阳光的反射次数，故与现有采用正四棱锥绒面结构的电池片相比，本发明电池片的反射率更低。
本发明还提供一种太阳能电池组件，其采用上述太阳能电池片，且组件中各电池片的棱锥第一侧面朝向相同。
太阳能电池组件一般包含多个电池片，组件中各电池片的棱锥第一侧面朝向相同，可发挥各电池片的棱锥绒面结构的陷光作用；在组件放置状态相同、且太阳光入射角度相同的情况下，与现有采用正四棱锥绒面结构电池片的组件相比，本发明组件中每个电池片的反射率都更低，故本发明整个组件的效率更高。
上述组件可竖直设置，如组件安装在建筑物的外立面上；当组件安装在南半球，组件优选朝北竖直设置；当组件安装在北半球，组件优选朝南竖直设置；且组件竖直设置时，组件中各电池片的棱锥第一侧面朝上设置更优。
组件竖直设置时，组件中各电池片的棱锥第一侧面朝上设置，可更好地应用本发明棱锥绒面结构的陷光作用；安装在南半球的组件朝北竖直设置、安装在北半球的组件朝南竖直设置，可使组件更好地得到太阳的辐照，提高组件的发电量。
上述组件可水平设置：当组件在南半球水平安装，组件中各电池片的棱锥第一侧面朝北设置，可更好地应用本发明棱锥绒面结构的陷光作用；当组件在北半球水平安装，组件中各电池片的棱锥第一侧面朝南设置，可更好地应用本发明棱锥绒面结构的陷光作用。
上述组件可倾斜设置，如采用现有组件的倾斜安装方式；当组件安装在南半球，组件优选朝北倾斜设置；当组件安装在北半球，组件优选朝南倾斜设置；且组件倾斜设置时，组件中各电池片的棱锥第一侧面朝上设置更优。
组件倾斜设置时，组件中各电池片的棱锥第一侧面朝上设置，可更好地应用本发明棱锥绒面结构的陷光作用；安装在南半球的组件朝北倾斜设置、安装在北半球的组件朝南倾斜设置，可使组件更好地得到太阳的辐照，提高组件的发电量。
本发明还提供一种太阳能电池方阵，其采用上述水平设置的组件，且方阵中相邻的组件拼接在一起。
本发明方阵中相邻的组件拼接在一起，即相邻的组件可以零间隙，可大大减少方阵的占地面积。
