Emil Eriksen.

During his studies, Emil has been modelling the flow of light around nanostructures. Nanostructures enable strong light concentration, which can lead to increased efficiency of various processes including upconversion. Upconversion is the process of merging two (or more) light particles into one with a larger energy. As nearly 20% of the energy incident from the Sun is mediated via light particles with an energy too low to be utilized by current commercial solar cells, upconversion pose a possible path for increased efficiency of next generation solar cells.

The main obstacle for the application of upconversion technology in energy harvesting applications is a too low upconversion efficiency. Accurate modeling capabilities enter as a key component in designing future high efficiency upconversion devices.

This PhD study is part of the SunTune project, funded by the Innovation Fund Denmark. The study was carried out at the Department of Physics and Astronomy, Science and Technology, Aarhus University.
