Abstract
A solar cell with a hetero junction structure includes a substrate, a first buffer layer, a second buffer layer, a second n-type amorphous semiconductor layer, a second p-type amorphous semiconductor layer, a first transparent conductive oxide (TCO) layer and a second TCO layer. A method for manufacturing the aforesaid solar cell includes the steps of forming the first n-type and the first p-type amorphous semiconductor layers respectively on a first surface and a second surface of the substrate, dope-treating the first n-type and the first p-type amorphous semiconductor layers by a gas plasma, and forming a first and a second intrinsic amorphous semiconductor layers respectively on the first n-type and the first p-type amorphous semiconductor layers.
