Perovskite, quantum dot and dye-sensitized solar cells

In my research group new solar cell devices based on solid state hybrid inorganic/organic nanoscale composites are constructed. We try to find new material combinations that are efficient and environmental friendly. We then use different advanced techniques to understand these devices from fundamental to applied level, and we also investigate different ways to prepare the solar cells on large scale. The results are then used to optimize the solar cell properties.

The solar cells may be divided into three different research areas: perovskite solar cells, quantum dot solar cells and dye-sensitized solar cells. The function of these types of solar cells is closely related and the results for one type of solar cell can often be used to improve and understand all three types of solar cells.
