Photovoltaic devices using silicon nanowires (SiNWs) have received much attention due to their excellent optical and electrical characteristics. From our previous reports, we presented SiNWs formed by vapor-liquid-solid (VLS) growth using Al which has been recently proposed as a new alternative catalyst. The effects of substrate temperature on SiNW formation were discussed and the SiNW-based solar cells were demonstrated. In this study, the effects of deposition time on SiNW formation were further investigated. Reflectance and absorbance properties of SiNWs with various deposition times were observed. Performances of radial p⁺-p-n-junction solar cell were also reported.
