Abstract
Disclosed is a solar cell including a semiconductor substrate, and a dopant layer disposed over one surface of the semiconductor substrate and having a crystalline structure different from that of the semiconductor substrate, the dopant layer including a dopant. The dopant layer includes a plurality of semiconductor layers stacked one above another in a thickness direction thereof, and an interface layer interposed therebetween. The interface layer is an oxide layer having a higher concentration of oxygen than that in each of the plurality of semiconductor layers.
Claims21
1-23. (canceled)
A solar cell comprising:
- a single crystalline semiconductor substrate;
- and
- a first conductive area formed on a first surface of the semiconductor substrate,
- wherein the first conductive area comprises a first polycrystalline semiconductor layer, an interface layer, and a second polycrystalline semiconductor layer sequentially stacked in a thickness direction, wherein the interface layer is an oxide layer having a higher oxygen concentration than each of the first polycrystalline semiconductor layer and the second polycrystalline semiconductor layer, and wherein a thickness of the first polycrystalline semiconductor layer is greater than that of the second polycrystalline semiconductor layer.
