VTT Technical Research Centre of Finland Ltd, Finland
The scope of the EU-funded LUMENTILE project is to combine custom electronics, optics and ceramic tiles into programmable high efficiency luminous elements which can be mass manufactured. In this report, different designs and validation results of the light guide structures for 20x20 cm2 luminous tiles for large area displays and luminaires are presented.

Broadband antireflection (AR) coatings are essential for improving the photocurrent generation of photovoltaic modules or the enhancement of visibility in optical devices. In this paper, we report a clean and simple method for fabricating nano-structured AR coating. Subwavelength-structured nipple arrays are directly patterned upon substrate using a self-assembled single-layer polystyrene (PS) nano-sphere array as etching masks. Nano-structure coatings exhibit excellent broadband and wide-angle antireflective properties. Besides, normal-incidence specular reflection matches with the theoretical prediction using a rigorous coupled-wave analysis model. This simple bottom-up technique and hybrid structural combination have the potential to significantly enhance the broadband and wide-angle antireflective properties for a number of optical systems that require high transparency, promising for reducing the manufacturing cost of nano-structured AR coatings.
