Optimization of charge separation in organic dye-sensitized solar cells (DSSCs) with different nanostructure films and redox mediators
Jan Sobuś
Abstract
The research performed in this PhD thesis revolves around optimization of a complex photo-physicochemical systems that DSSC are. Number of aspects are taken into account: the type and morphology of the photoanode material, type of the utilized dye, various types of electrode surface treatment, type of electrolyte redox couple and additional electrolyte constituents. Kinetic processes occurring in these devices on the timescales from fs to s are probed using a set of measuring techniques including: laser spectroscopy (UV-VIS, IR, transient spectroscopy), flash photolysis, electrochemical impedance spectroscopy, current-voltage measurements together with SEM and TEM imaging. Laboratory work is supported by the theoretical considerations in the form of creation and implementation of the algorithm, which optimizes parameters of single and tandem solar cells in order to obtain the highest efficiency. All the conclusions are drawn from the set of 6 publications being the backbone of the thesis and are presented together with a short description of operating principles of DSSCs and measuring techniques.- Record ID
