Advanced Characterization and Modelling of Charge Transfer in Perovskite Solar Cells
This thesis includes the work done in ICIQ about fabrication, characterization, and modelling of hybrid perovskite solar cells.
Coming from other kind of solar cells, the analysis tools, the methods, and, most importantly, their interpretation have been analysed and adapted to this new kind of device.
Then, these techniques have been employed for analysing and understanding the influence of four different and novel hole transport materials on perovskite solar cells open circuit voltage.
Another study focussed on the electrons’ accumulation in devices employing small variations in each stacked layer thickness and analysing the samples using the same techniques.
From my international stay in Dr. Piers Barnes and Prof. Jenny Nelson groups in Imperial College London, another study was originated: we interpreted complex impedance spectroscopy results when applied on perovskite solar cells with mobile ions.
Finally, all the free software that has been developed for data acquisition, processing, and for drift-diffusion modelling of perovskite solar cells has been exposed.
