Recently, researchers have shown an increased interest in silicon nanowires (SiNWs) as a promising candidate for solar cell applications due to their unique optical and electrical properties. Among many techniques to fabricate SiNWs, a metal-catalyzed electroless (MCEE) etching technique is one of the most favorable method. The MCEE method has advantages in cost, procedure, and allows us to control the features of SiNWs. This work aims to fabricate SiNWs/PEDOT: PSS hybrid solar cell using the MCEE method. Furthermore, gold nanoparticles (AuNPs) were used to improve the light absorption of the device due to localized surface plasmon excitation. The SiNW arrays with a length of 480 nm were used as a substrate of the cell. Then, we varied the concentration ratio of PEDOT: PSS and AuNPs. Finally, the performance of PEDOT: PSS/AuNPs/SiNWs hybrid solar cell with changing the concentration ratio of PEDOT: PSS and AuNPs was compared with PEDOT: PSS/SiNWs hybrid solar cell.
