“…Recently, researchers have shown an interest in the development of the SiNWs as a promising candidate for a wide range of applications in solar cells, catalysts, and sensors due to the high surface area of the SiNWs [8]- [11]. The SiNWs/organic semiconductor hybrid solar cells have shown an increase in the power conversion efficiency (PCE) due to the function of the organic layer as a hole-transporting path and the formation of a heterojunction with Si [12]- [14].…”

We fabricated silicon nanowires (SiNWs) using a metalcatalyzed electroless etching method, which is known to be a low-cost and simple technique. The SiNW arrays with a length of 540 nm were used as a substrate of SiNWs/PEDOT:PSS hybrid solar cell. Furthermore, gold nanoparticles (AuNPs) were used to improve the light absorption of the device due to localized surface plasmon excitation. The results show that the short-circuit current density and the power conversion efficiency increased from 22.1 mA/cm 2 to 26.0 mA/cm 2 and 6.91% to 8.56%, respectively. The advantage of a higher interface area between the organic and inorganic semiconductors was established by using SiNW arrays and higher absorption light incorporated with AuNPs for improving the performance of the developed solar cell.
