Abstract

Based on the Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS), the specific surface and interface characteristics of emitter region of commercial mono-crystalSisolar cells were examined. Four chemical compositionsC,O,Si, andPwere detected, and the atomic concentrations (%) ofCandOat the surface were much higher than their solid solubility in mono-crystalSi. The high concentration ofCandOat the surface was attributed to adhered remains. The single elementSi, stable oxideSiO2, as well as intermediate oxidation states such asSi1+andSi3+corresponding toSi2OandSi2O3, respectively, have been analyzed. The atomic concentrations (%) of these compositions and their respective chemical states at the surface and interface are likely correlative to the various defects such as electronic-like ramification of hanging bonds, vacancy cluster, or dislocations. Furthermore, the normalized quantum efficiency (QE) of the solar cells made from the wafers was measured to be lower than 74% at short wavelength (
