Modeling and Fabrication of Luminescent Solar Concentrators towards Photovoltaic Devices

Sun light concentration is a way to decrease photovoltaic devices cost. An original method to concentrate light is the use of Luminescent Solar Concentrators (LSC), which act as waveguide to concentrate light towards the photovoltaic (PV) cells. To improve the LSC efficiency, the addition of a Photonic Band Stop (PBS) is investigated. Simulations were realized for different systems, with and without PBS. They enabled to distinguish loss mechanisms, and to determine what improvement may be expected with an additional photonic component. Then LSC and PBS were realized and characterized. The fabrication of the complete device coupling the both parts is challenging.
