Charge transport and recombination layer for perovskite solar cells

Resum

The scope of this thesis is the study of vacuum deposited single junction and tandem perovskite solar cells and the optimization of charge transport layers, to maximize the efficiency and stability of the devices. To reach this target, methodologies to characterize the charge transport layers must be developed and the device stack needs to be optimized. The work has been structured in three sections: Chapter 3, about the influence of doped charge transport layers on p–i–n perovskite solar cells. Chapter 4, developing the application of (RuCp*mes)2 as a sublimable n-dopant for n–i–p perovskite solar cells. And in Chapter 5,about the fabrication of vacuum-deposited CH3NH3PbI3 – CH3NH3PbI3 tandem solar cells.
