Process Development for Wet Chemical Fabrication of Cu2ZnSn(S, Se)4 Solar Cells

Zusatztext

In order to cope with the ever-growing global energy demand and the imminent threat of climate change, a shift from fossil fuels and nuclear energy to renewable energies such as solar energy is inevitable. Furthermore, highly cost-effective solar cells, especially regarding the used materials and fabrication methods, would facilitate a large-scale implementation of photovoltaics. This work deals with the novel non-toxic and earth-abundant solar cell material kesterite and an applicable high-throughput fabrication method. The development of fabrication processes is presented and device optimization is conducted. A major focus lies on bandgap tuning and engineering of the absorber material establishing a solid foundation for future device improvements.
