Black silicon nanotextures offer exceptionally low levels of reflectance and are of interest to the field of solar photovoltaics. The nanowires that form this texture create a graded refractive index, allowing light to be absorbed with high efficiency. Explored here is the application of these nanotextures on top of conventional... [Read More]

Black silicon nanotextures offer significant optical performance improvements when applied to crystalline silicon solar cells. Coupled with conventional pyramidal textures, to create so–called hybrid black silicon, these benefits are shown to be further enhanced. Presented here is a comprehensive analysis of different variations of this texture, coupled with typical anti–reflectance... [Read More]

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,... [Read More]

In developing a solution to tackle the lost energy potential of reflection of light from the surface of solar cells – using nanoscale textured ‘black’ silicon - a new, ground-breaking innovation emerged. The Variable Angle Reflectometer (VAR) is designed to measure the reflectance of a given surface, resolved not only... [Read More]

Surface reflectance is a practical metric of the optical performance of a material. Applications, such as glass manufacturing, light sensing, satellite reflectors, and photovoltaics, depend on their reflectance properties and generalized optical performance. Reflectance measurements are rarely reported comprehensively, with only a single angle of incidence common in most datasets.... [Read More]
