Energy materials and solar cells - TEM Gemini Centre
Energy materials and solar cells
TEM has proven to be a crucial characterization tool to understand and improve the efficiency of both conventional and novel types of solar cells. The TEM Gemini Centre activities within solar cells include both studies of conventional silicon solar cell materials and new materials.
This include research activities like:
- TEM characterization of InAs quantum dots in GaAs: measuring band gaps with electron energy loss spectroscopy.
- Electronic properties of interfaces within a nanowire-based solar cell TEM and advanced photon emission.
- CuO-based solar cells, where TEM is used to investigate advanced photon emission
- Developing a prototype of high efficiency solar cell based on epitaxial growth of a III-V cell on top of a Si cell.
The TEM Gemini Centre is participating in the Centres for Environment-friendly Energy Research (FME) on solar cells.
Projects within battery technology
TEM is one of the primary tools to characterize and understand the behaviour of the anode materials.
- Development of Si/Graphite based composites as anodes in commercial Li-ion batteries. composites as a function of structure, morphology and cycling conditions.
- Development of high capacity anodes based on metal hydrides for use in conversion electrodes in Li-ion batteries.
- Development of cathode materials for use in Li-air batteries.
