太阳能电池及制造太阳能电池的方法
摘要：
本发明涉及太阳能电池及制造太阳能电池的方法。一种用于制造太阳能电池的方法可以包括以下步骤：形成发射区，所述发射区与第一导电类型的半导体衬底形成p-n结；在所述半导体衬底上形成钝化层；在所述钝化层上形成包含第一导电类型的杂质的掺杂层；以及通过将激光束照射在所述半导体衬底上以使所述第一导电类型的杂质扩散到所述半导体衬底中，在所述半导体衬底处局部地形成背面场区。
摘要（英）：

The invention relates to a solar cell and a method for manufacturing the same. The method for manufacturing a solar cell may include forming an emitter region that forms a p-n junction with a semiconductor substrate of a first conductive type, forming a passivation layer on the semiconductor substrate, forming a dopant layer containing impurities of the first conductive type on the passivation layer, and locally forming a back surface field region at the semiconductor substrate by irradiating laser beams onto the semiconductor substrate to diffuse the impurities into the semiconductor substrate.
