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/cm 2. © 2012 IEEE.hybrid solar cell; organic semiconductor; PEDOT:PSS; silicon nanostructure[SDGs]SDG73 ,4-ethylenedioxythiophene; Chemical wet etching; Energy efficient; Heterojunction solar cells; Hybrid solar cells; PEDOT:PSS; Poly(styrene sulfonate); Power conversion efficiencies; Silicon nanostructures; Silicon nanowire arrays; Silicon nanowires; Vertically aligned; Conducting polymers; Conversion efficiency; Energy efficiency; Heterojunctions; Nanowires; Semiconducting organic compounds; Wet etching; Solar cellsconference paper10.1109/PVSC.2012.6317970
