英文摘要 | Passivation of c-si surface was processed by hot-wire chemical vapor deposition through the pretreatment of atomic hydrogen. the interfacial properties were examined by the admittance spectroscopy. the interfacial property is sensitive to the atomic hydrogen treatment time t(h) of c-si substrates rather than the crystallization of the buffer layer. it was found that the th of 30-60 s is essential for the low defects states in the emitter. the interfacial morphology between nano-crystalline si (nc-si:h) layer and c-si substrates was investigated by high resolution transmission electron microscopy in cross section geometry. the amorphous, mixed epitaxial/amorphous and epitaxy phases were observed as the buffer layer growth at hydrogen dilution ratios of 0, 0.5, 0.86, 0.97, respectively. by optimizing th and using an epitaxial silicon buffer layer, the efficiency of 17.36% of solar cell with the structure of n epi-si/i epi-si/p c-si was fabricated at 250 degrees c. |
