Method for making solar cell |
摘要 |
A method for making a solar cell includes following steps. A silicon substrate is provided, and the silicon substrate has a first surface and a second surface opposite to the first surface. A patterned mask layer is located on the second surface, and the patterned mask layer includes a number of bar-shaped protruding structures aligned side by side. A slot is defined between each two adjacent protruding structures to expose a portion of the second surface of the silicon substrate. The exposed portion of the second surface is etched to form a protruding pair. The mask layer is removed. A doped silicon layer is located on the three-dimensional nano-structures. An upper electrode is applied on at least part of a surface of the doped silicon layer. A back electrode is placed on the first surface of the silicon substrate.
