Abstract
Next-generation optoelectronic devices are required to be more compact and light-weight, and to achieve new optical functionalities at the same time. While these are challenging for current hardware designs, nanophotonics can be a key strategy to realize an optoelectronic device with desired functions in a smaller form factor. In this work, we will explore how nanophotonics can be leveraged to enhance the performance of optoelectronic devices, focusing on photovoltaics and imaging application. In the first part, we will see how we can design a thin, single layer of nanostructures that can function as both antireflection coating and light-trapping layer. We will experimentally demonstrate the effectiveness of these light-trapping antireflection coatings (LARCs) on 2.8-µm-thick c-Si solar cells and notably improve the efficiencies. In the second part, we will present a new type of imaging technology that can discern surface textures by utilizing a set of metasurface-driven pixels (i.e. meta-pixels). The metasurfaces in each type of pixel are engineered to achieve desired angular sensitivities, which enable efficient perception of texture. Furthermore, we will experimentally demonstrate the meta-pixels and show their efficacy through reconstructed texture images that effectively visualize differences in textures.
