利用晶体硅对太阳能电池光接收表面进行钝化
摘要：
本发明描述了利用晶体硅将太阳能电池的光接收表面钝化的方法以及所得的太阳能电池。在一个示例中，太阳能电池包括具有光接收表面的硅基板。在所述硅基板的所述光接收表面上方设置有本征硅层。在所述本征硅层上设置有N型硅层。所述本征硅层和所述N型硅层中的一者或两者是微晶或多晶硅层。在另一个示例中，太阳能电池包括具有光接收表面的硅基板。在所述硅基板的所述光接收表面上设置有钝化介电层。在所述钝化介电层上设置有N型微晶或多晶硅层。
摘要（英）：

Methods of passivating light-receiving surfaces of solar cells with crystalline silicon, and the resulting solar cells, are described. In an example, a solar cell includes a silicon substrate having a light-receiving surface. An intrinsic silicon layer is disposed above the light-receiving surface of the silicon substrate. An N-type silicon layer is disposed on the intrinsic silicon layer. One or both of the intrinsic silicon layer and the N-type silicon layer is a micro- or poly-crystalline silicon layer. In another example, a solar cell includes a silicon substrate having a light-receiving surface. A passivating dielectric layer is disposed on the light-receiving surface of the silicon substrate. An N-type micro- or poly-crystalline silicon layer disposed on the passivating dielectric layer.
