METHOD OF MANUFACTURING CRYSTALLINE SILICON SOLAR CELLS USING CO DIFFUSION OF BORON AND PHOSPHORUS |
摘要 |
<p>A method of manufacturing a crystalline silicon solar cell, subsequently including: providing a crystalline silicon substrate having a first side and a second side opposite the first side; pre-diffusing Phosphorus into a first side of the substrate to render a Phosphorus diffused layer having an initial depth; blocking the first side of the substrate; exposing a second side of the substrate to a Boron diffusion source; heating the substrate for a certain period of time and to a certain temperature so as to diffuse Boron into the second side of the substrate and to simultaneously diffuse the Phosphorus further into the substrate.</p> |
