Metasurface Electrodes for Solar Cells and Display Technologies

Metasurface concepts have enabled the creation of a wide range of passive, flat optical components for optical wavefront shaping, polarization-conversion, and redirection of light. These elements have by now reached very high performance levels. However, for many optoelectronic devices (e.g. solar cells, sensors, and displays) it is not sufficient to have metasurfaces that serve as mode converters between different types of free-space waves. We also need metasurfaces that effectively interface free-space photons with optical elements that emit or absorb light waves. In this presentation, I will describe how initial work on the design of metasurface electrodes in organic solar cells and sensors has led to the development of advanced OLED displays.
