Fraunhofer Institute for Solar Energy Systems ISE
High conversion efficiencies and thus low photovoltaic electricity costs can only be achieved with optimal and cost-efficient materials. At Fraunhofer ISE, we achieve excellent electronic properties for silicon, organic, III-V and perovskite semiconductors through in-depth analyses and optimized processes. Building on this, we use simulation tools to design optimized solar cell architectures and implement them in our laboratories. This results in groundbreaking cell architectures such as the TOPCon silicon solar cell developed by us, which has become an industrial standard worldwide.
As the efficiency of silicon solar cells is approaching its theoretical limit, we are developing the next generation of solar cells based on multi-junction solar cells. We are using our comprehensive experience with III-V semiconductors to produce next-generation tandem solar cells with new and potentially more cost-effective semiconductors such as perovskites. In module production, we are focusing on new topologies such as matrix shingling, which achieves particularly aesthetic results in combination with our MorphoColor® technology. We are also conducting research on tandem modules that allow the highest module efficiencies in fixed installations or in concentrating tracking systems.
