Metal-assisted chemically etched black silicon for crystalline silicon solar cells
Abstract
Nanoscale textured silicon has the potential to overcome the optical challenges faced in the photovoltaic (PV) industry that remain in maximisation of photo-generation. However, due to the high aspect ratio of these structures, the electrical losses remain a huge challenge for this type of architecture. In this work, we use a Metal Assisted Chemical Etch (MACE) process to fabricate black silicon and analyse the influence on morphology of etch time and silver nitrate concentration. Furthermore, we show good surface passivation of the nanostructures using atomic layer deposition of AlOx, and study the optical influence of dual-passivation stacks using ultra-thin oxides.
