Challenges and Prospects of Bio-Inspired and Multifunctional Transparent Substrates and Barrier Layers for Optoelectronics.

Abstract

Bio-inspiration and advances in micro/nanomanufacturing processes have enabled the design and fabrication of micro/nanostructures on optoelectronic substrates and barrier layers to create a variety of functionalities. In this review article, we summarize research progress in multifunctional transparent substrates and barrier layers while discussing future challenges and prospects. We discuss different optoelectronic device configurations, sources of bio-inspiration, photon management properties, wetting properties, multifunctionality, functionality durability, and device durability, as well as choice of materials for optoelectronic substrates and barrier layers. These engineered surfaces may be used for various optoelectronic devices such as touch panels, solar modules, displays, and mobile devices in traditional rigid forms as well as emerging flexible versions.
