Tandem Solar Cells Group

The group focuses on the research and development of cost-effective small-area high-efficiency (> 30%) perovskite on silicon tandem solar cells and mini-modules that can be upscaled to large-area devices with good long-term stability. It is dedicated to the optimization and innovation of the materials, architectures and fabrication techniques for both crystalline silicon and perovskite solar cells, in order to develop reliable, reproducible and industrially viable low-cost solutions for perovskite/Si tandems. The group’s research includes the development of perovskite solar cells and mini-modules suitable for either single-junction or tandem applications, specially designed & optimized silicon bottom cells and interconnection layers for tandem integration, as well as encapsulation, reliability and outdoor performance studies of perovskite and tandem solar cells and mini-modules.
