Abstract

The vertically aligned silicon nanowire (SiNW) arrays have been fabricated by using an electroless etching method

and then the nanowire arrays were modified by dipped the SiNWs in alkali solution. The effect of alkali solution on the morphology and photoelectric property of SiNWs were studied. The results showed that the spectral response of the modified SiNW arrays cell was obviously improved compared to the bunched SiNWs cell and textured cell. The phenomenon of wavelength red shift for maximum quantum efficiency was discovered

which confirmed that the photoelectric performance can be significantly improved at long wave band by alkali solution modified

but low spectral response at short wave period showed that charge carriers were seriously recombined at silicon nanowires near surface. When the alkali solution modified time increase to 60 s

the photoelectric response was weakened. In addition

the effect mechanism of alkali solution modify on the spectral response of SiNWs cell was tentatively analyzed and interpretation in detail.
