Since light management is crucial for the performance of optoelectronic devices, extensive efforts, such as texturing semiconductor layers and implementing plasmonic metal nanostructures or transparent dielectric structures, have been made to enhance the optical properties of the devices. It is advantageous that the implementation of transparent dielectric structures in the devices enables us to improve optical properties with minimized parasitic absorption loss and little deterioration of electrical property in the active layer. By properly designing geometry of structure and appropriately selecting dielectric material property, we can effectively control the efficiency of light transmission, extraction, scattering, or reflection. Hence, efficient light management using lossless dielectric structures gives great potential for improving the performance of the optoelectronic devices such as photovoltaic cells, photodetectors, light emitting diodes, and displays. In this review article, we will summarize the latest research progress on light management strategies for high-performance optoelectronic devices using transparent dielectric micro and nanostructures.
