Abstract

A novel method of combining photolithography, wet chemical etching and oxidation process was proposed to fabricate large area of silicon microwire (SiMW) arrays. The dimensions of the SiMWs can be easily controlled by photomask and etching conditions. Solar cells based on the heterojunction between SiMW and double-walled carbon nanotubes (DWNTs) were constructed. The initial test on the DWNT/SiMW shows efficiency (η) of 0.59%. By adding a few drops of HBr/B₂ electrolyte, the efficiency was improved to 1.96% with J _sc=19.2 mA/cm² and V _oc=0.35 V, FF=29.2%, showing the potential of SiMWs in photovoltaic applications.
