Stretching the efficiency limit of mass-producible solar cell and solar fuel devices by multi-junction based absorber structures

11:20 - 11:50 Auditorium between Building 4 and 5

With the advent of the exciting new material class of inorganic/organic perovskite absorbers, a realistic option has emerged for multi-junction solar cells combining high efficiency with industrial manufacturability. In order to enable future solar-cell efficiencies to exceed the theoretical efficiency limit for single junction devices, we have realigned our research activities over the past years to focus on these absorber material class with a view to applications in multi-junction devices. In collaboration with international partners we have demonstrated the feasibility and pushed the performance of such structures.

In this talk we will highlight recent progress in absorber and contact materials as well as adapted processing methods and device design for two-terminal silicon-perovskite tandems. We will also highlight our recent developments in multi-junction devices for solar fuel generation, based on wide-bandgap oxide absorbers.
