Hut-like pillar array Si solar cells

A good texturing pattern for solar cells needs to combine low Reflectance over a large wavelength range and low surface recombination to maximize the output. Nanowire and pyramid patterns offer low Reflectance in the longer and shorter wavelength regions respectively. This paper introduces an exciting new “hut” like texturing pattern with excellent performance, improving that of nanowires and pyramids; over the long and short wavelength ranges respectively. Furthermore, we analyze the effect of different structural parameters such as height, diameter, Surface Coverage (SC) and ϑ, on the solar cell performance.
