摘要：

A tunnel silicon oxide (SiOx) and magnesium (Mg) electron-selective structure and its application for n-type c-Si solar cell are carefully studied in this work. The fabrication, reflectance, passivation quality, contact resistivity, and thermal stability of the SiOx/Mg contact are investigated. The optimized thermally annealed SiOx at 700 degrees C leads to the best surface passivation and acceptable contact resistivity for the SiOx/Mg contact on an n-type c-Si wafer, i.e., the lowest single-side surface saturated dark current (J(0)) of about 100 fA cm(-2) and the contact resistivity of less than 30 m omega cm(-2) are achieved. In general, the SiOx/Mg structure exhibits robust performances to be used as an electron-selective passivated contact for n-type c-Si solar cells.
