| 英文摘要 | Abstracta radial p-n junction solar cell based on vertically free-standing silicon nanowire (sinw) array is realized using a novel low-temperature and shallow phosphorus doping technique. the sinw arrays with excellent light trapping property were fabricated by metal-assisted chemical etching technique. the shallow phosphorus doping process was carried out in a hot wire chemical vapor disposition chamber with a low substrate temperature of 250°c and h2-diluted ph3 as the doping gas. auger electron spectroscopy and hall effect measurements prove the formation of a shallow p-n junction with p atom surface concentration of above 1020?cm?3 and a junction depth of less than 10?nm. a short circuit current density of 37.13?ma/cm2 is achieved for the radial p-n junction sinw solar cell, which is enhanced by 7.75% compared with the axial p-n junction sinw solar cell. the quantum efficiency spectra show that radial transport based on the shallow phosphorus doping of sinw array improves the carrier collection property and then enhances the blue wavelength region response. the novel shallow doping technique provides great potential in the fabrication of high-efficiency sinw solar cells. |
