METHODS OF THERMAL PROCESSING A SOLAR CELL |
摘要 |
Embodiments of the invention contemplate the formation of high efficiency solar cells and novel methods for forming the same. Embodiment of the invention can be used to form a solar cell that has doped regions that act as a back surface field. The methods and apparatus disclosed herein may include the use of a doping source, a rapid annealer and a slow annealer. One embodiment of the methods used to form an improved emitter structure include disposing an amount of a dopant atom in a substrate and performing two or more thermal processing steps to cause the dopant to diffuse deeper into the substrate to achieve a desirable multi-facet doping profile.
