Description of field of research:
Combining organic molecules onto silicon solar cells to create tandem devices represents one route to overcoming the absolute efficiency limit that current silicon solar cells are approaching. This is accomplished through the singlet fission down-conversion process wherein one high energy photon absorbed in the organic layer is converted to up to two electron-hole pairs in the underlaying silicon solar cell. But to this point, understanding of the interface and energy transfer between the organic molecules and silicon is limited. In this project you will vary the interface between the molecular layer and a silicon wafer and study the effect on the coupling across the interface.

This project will suit a student who enjoys physics, electronics & photovoltaics.
You will work in state-of-the-art characterization and fabrication facilities housed in SPREE. Our research group is interdisciplinary, with 6 PhD students. The project will be a combination of laboratory and analysis work.
The student will learn aspects of conventional silicon solar cell fabrication and characterization, as well as advanced characterization techniques and data analysis. The data produced by the project will inform the next generation development of singlet fission enhanced silicon solar cells.
