▲ [13p-PA3-2] Fabrication of Silicon Nanowires by Metal-Catalyzed Electroless Etching Method and Their Solar Cell Application
Keywords:SiNWs, hybrid solar cell, PEDOT: PSS
Recently, there has been an increasing interest in the development of silicon nanowires (SiNWs) as a promising candidate for a wide range of applications due to their unique optical and electrical properties. Generally, there are many techniques to fabricate SiNWs such as vapor-liquid-solid (VLS) growth, reactive ion etching (RIE), and metal-catalyzed electroless (MCEE) etching which is the most favorable method. The MCEE method is uncomplicated to control the cross-sectional shape, diameter, length, and orientation. Moreover, this method can also be carried out in a chemical lab without expensive equipment. This study used the MCEE method to fabricate SiNW arrays for improving hybrid solar cell performance. We used SiNW arrays as a part of inorganic semiconductor and used poly(3,4-ethylene dioxythiophene): poly(styrene sulfonate) (PEDOT: PSS) as a part of an organic semiconductor. Finally, the performance of PEDOT: PSS/SiNWs hybrid solar cell with the difference of nanowire length will be compared with PEDOT: PSS/planar Si hybrid solar cell.
