| 英文摘要 | si/zno core/shell nanowire (nw) arrays were fabricated using atomic layer deposition of zno shell on n-si nw arrays prepared by metal assisted electroless etching method. scanning electron microscopy, transmission electron microscopy and x-ray diffraction were utilized to characterize the core/shell structures. water splitting performance of the core/shell structures was preliminarily studied. the si/zno core/shell nw arrays yielded significantly higher photocurrent density than the planar si/zno structure due to their low reflectance and high surface area. the photoelectrochemical efficiency was found to be 0.035 and 0.002 % for 10 mu m-long si/zno nw array and planar si/zno sample, respectively. these results suggested that core/shell structure is superior to planar heterojunction for pec electrode design. we demonstrated the dependence of photocurrent density on the length of the core/shell array, and analyzed the reasons why longer nw arrays could produce higher photocurrent density. the relationship between the thickness of zno shell and the photoconversion efficiency of si/zno nw arrays was also discussed. by applying the core/shell structure in electrode design, one may be able to improve the photoelectrochemical efficiency and photovoltaic device performance. |
