Development of all thin-film perovskite-on-chalcogenide tandem photovoltaics
About the project
Estimations suggest that increased efficiency of photovoltaic (PV) appliances above the Shockley-Queisser single-junction limit is related to the creation of tandem devices. The EU-funded PERCISTAND project will focus on the development of innovative materials and processes for perovskite on chalcogenide tandem appliances. The project will focus on four-terminal tandem solar cell and module prototype testing on glass substrates. The goal is to obtain efficiency, stability and large-scale manufacturability for thin film PV that will be competitive with existing commercial PV technologies. The results of the project will support the EU in regaining predominance in thin film PV research and production.
PERCISTAND’s power conversion efficiency targets are:
- ≥ 20 % semi-transparent perovskite PV
- ≥ 10 % NIR-illuminated chalcogenide PV
- ≥ 30 % tandem cell
- ≥ 25 % tandem module
