We showcase the optical performance of our hybrid black silicon (hb-Si) nanotextures, as measured with our bespoke angle-resolved spectrophotometer (ARS) and delve into a real-world analysis of its day-to-day performance. Using our novel reflectance measuring technique we can combine theoretical solar irradiance with measured surface reflectance, resolved against wavelength, angle, and polarisation simultaneously, to get a unique insight into how solar cells would perform, optically, when placed anywhere in the world. Here, we take several locations, including Manchester in the U.K., Narangba in Australia, and Reykjavík in Iceland, and perform such a theoretical analysis for each at various points throughout the year, forming a comparison study with a traditional pyramidal textured sample under the same conditions.
