Photon Management for Solar Energy Harvesting
Our main endeavors are to exploit different (often multiple) photonic phenomena to enhance solar energy harvesting and control light emission characteristics for various purposes. To do so, we theoretically explore novel approaches in transformation optics, plasmonics, and nanophotonics in general for tailoring light propagation and light-matter interaction. Spatial and spectral light scattering properties of ordered and disordered structures with features of various size scales are investigated. To address disordered systems, we develop our own analytical and numerical methods. We aim to give insights on how to engineer these structures in order to obtain desired functionalities and performance. In the purpose of solar cell absorption enhancement, for example, a spectrally broad response is desired as one is interested to capture the whole UV to near-infra red part of the solar spectrum.
