Prof. Hernan Miguez (Spanish National Research Council, Sevilla, Spain) will discuss different optimized light harvesting or emission strategies that make use of solution processed optical materials integrated into optoelectronic devices. Approaches based on the inclusion of dielectric and metal particles, periodically textured surfaces or dielectric mirrors will be presented, and the different scattering or near field enhancement effects involved discussed. The interplay between the electrical and optical properties of the devices will also be addressed. Actual examples of device realization will be provided.
