Abstract

Abstract:
The efficiency of most photonic-based structures and devices depend on how much light is interacting at the surfaces and within the structures. Light trapping and capture is therefore of significant importance in the manufacturing of efficient and high performance light energy capture devices. We have demonstrated that subwavelength structures with dimensions in order of 300-400 nm reduce reflections down to 5% over wide range of wavelengths from 300nm to 900nm. In addition, we have developed novel nano pyramid structures that can be transferred on glass to act as antireflective coatings and self-cleaning surfaces. I will present the principles of technologies used and outcome of this work. Potential applications will also be discussed.
