Nanostructured dielectric and metallic photonic architectures can concentrate the electric field through resonances, increase the light optical path by strong diffraction and exhibit many other interesting optical phenomena that cannot be achieved with traditional lenses and mirrors. The use of these structures within actual  devices  will  be  most  beneficial  for  enhanced  light absorption in thin solar cells, photodetectors and to develop new sensors and light emitters. However, emerging optoelectronic devices rely on  large  area  and  low  cost  fabrication  routes such as roll  to roll or solution processing, to cut  manufacturing costs and increase  the production throughput. If the exciting properties exhibited photonic structures are to be implemented in these devices then, they too have to be processed in a similar fashion as the devices they intend to improve. In this presentation, I will describe different low cost and large area photonic architectures that coupled to these new types of technologies facilitate enhanced light matter interaction within the active layer and are fully compatible with current manufacturing processes.
