Third European Workshop on OPTICS FOR SOLAR ENERGY

(formerly known as Nanophotonics for Solar Energy)

SolarCells

The Third European Workshop on Optics for Solar Energy will review current trends and recent developments in the field of optics and nanophotonics for solar energy conversion devices. The workshop covers various topics such as (nano-)optical light management for single-junction and tandem solar cells and solar fuel devices, photon up- and down conversion, optical modelling of mono- and bifacial solar modules and energy yield calculations. The work­shop is organized by the Helmholtz Excellence Network SolarMath. We encourage the participants to not only present their latest results but also to address problems and open questions – this might help to identify possible topics for collaboration.

We organize the workshop as a hybrid event, where the speakers can present on site in Berlin or online.
