摘要:
A silicon solar cell is formed with an N-type silicon layer on a P-type silicon semiconductor substrate. An antireflective and passivation layer is deposited on the N-type silicon layer, and then an aluminum ink composition is printed on the back of the silicon wafer to form the back contact electrode. The back contact electrode is sintered to produce an ohmic contact between the electrode and the P-type silicon layer. The aluminum ink composition may include aluminum powders, a vehicle, an inorganic polymer, and a dispersant. Other electrodes on the solar cell can be produced in a similar manner with the aluminum ink composition.
摘要(中):
在P型硅半导体衬底上形成有N型硅层的硅太阳能电池。 在N型硅层上沉积抗反射和钝化层,然后在硅晶片的背面印刷铝墨组合物以形成背接触电极。 背接触电极被烧结以在电极和P型硅层之间产生欧姆接触。 铝墨水组合物可以包括铝粉,载体,无机聚合物和分散剂。 太阳能电池上的其他电极可以以与铝墨水组合物类似的方式制造。
