Abstract :
In this work, we develop a technique to form vertically aligned silicon nanowire (SiNW) arrays without aggregation at the top by cost and energy efficient metal-assisted chemical wet etching. The SiNW/PEDOT:PSS heterojunction solar cells are also fabricated with nanowire length varying from 0.758 °m to 5.27 °m. The 0.758-°m-SiNW/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) solar cell has the best power conversion efficiency of 8.65% and short circuit current density of 24.94 mA/cm2.
