A molybdenum nanorod pattern consisting of hexagonal closed-packed arrays was fabricated on soda lime glass (SLG) substrates. These nanostructures, which were fabricated by transferring two-dimensional nano-patterns onto a glass substrate using a combination of polystyrene (PS)-based nanosphere lithography (NSL) and reactive ion etching (RIE), enhanced the diffusion length by increasing the surface area. To fabricate the nanorod pattern on the SLG, the proper conditions for selective etching were investigated via different reactive ion gas conditions and power levels. The corresponding optical and structural properties were examined using a scanning electron microscope (SEM) and reflectance spectroscopy. We optimized the conditions of fabricating hexagonal closed-packed patterned molybdenum nanorod for use in conjunction with bottom electrodes of CIGSeS photovoltaic (PV) cells by analyzing the power conversion efficiency of CIGSeS PV cells.
