This site is on an event in the past.

In October 2021, we organize the Third European Workshop on Optics for Solar Energy.


The Webinar 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 webinar covers various topics such as (nano-)optical light management for single-junction and tandem solar cells and solar fuel devices, optical modelling of mono- and bifacial solar modules and energy yield calculations. The webinar is organized by the Helmholtz Excellence Network SolarMath in cooperation with OptecBB and consists of talks by the following speakers:
