Hybrid Nodes for Highly Efficient Light Concentrators
The meaning of solar energy for future decentralized power supply will largely depend on both efficiency and cost of solar to electrical power conversion. All kinds of conversion strategies including photovoltaics, concentrated solar power, solar to fuel and others would benefit from efficiently collecting solar power on large areas. For this reason luminescent solar concentrators have been developed for over thirty years, but due to waveguide losses their maximum size is still limited to a few centimetres.
The key idea in this field of research is to exploit the node of a dielectric TE1 mode in order to decrease waveguide losses. A node is a position in the waveguide where no intensity is found. A thin film placed in this node remains largely “invisible” for the propagating mode.
Based on this idea, the project was carried out from 2015 to 2020. Within this project it was demonstrated that node modes allow reduced waveguide losses, thus enabling the collection of light inside waveguide grating couplers with drastically reduced thickness compared to conventional waveguide designs.
The reduced waveguide losses have inspired new solar concentrator concepts such as waveguide stacking, the combination of mirror structures with reduced propagation losses (Zero-Order collection) in low-guidance waveguides, the light-induced self-adaption of silver nanoparticles, and time-variant systems which promise to break the radiance limit in passive devices.
Beyond these newly arisen and still ongoing fields of research, the project has led to numerous scientific publications, patent applications, and the development of measurement techniques and technological advances for large-scale multilayer polymer waveguides compatible to roll-to-roll processing.
