ELDORADO has three main sequential objectives, the first of which is the development of a 2D perovskite active layer where an efficient 2D or quasi-2D perovskite absorber layer will be optimized for a tandem device with a silicon-based (c-Si) bottom cell. The optimal composition of the perovskite material will be guided by simulations and advanced characterization optimizing the light harvesting and transmission.
The second objective is the development of a suitable layer of silicon nanoparticles to be inserted into the perovskite absorber or at the 2D perovskite/charge transporting layer interfaces to optimize the light management and the efficiency of the device.
The third and last objective is the realization of a tandem proof-of-concept perovskite/c-Si tandem device employing a two-terminal mechanically stacked architecture with power conversion efficiency above the current state of the art.
