This research proposal focuses on the development of dyes, dye/semiconductor interfaces, electrolytes and semiconducting materials for p-type dye sensitized solar cells (DSCs). The project is being undertaken by an established team of chemists and physicists from the University of Basel, who have a strong and productive working-relationship. The project specifically targets the underdeveloped, but critically important, p-type semiconductor/dye interface. The interdisciplinary research in this field is crucial to an understanding of the complex chemical and physical processes in p-type DSCs and will be highly effective because of our team's long-standing experience and research facilities. We will develop new nanomaterials for p-type DSCs and using an established interdisciplinary approach involving synthetic chemists and physicists, we will develop semiconducting p-type nanoparticles in parallel with the synthesis of dyes and trials of electrolytes to produce optimized material combinations for p-type DSCs. The chemistry team will focus on the design, synthesis and development of dyes (sensitizers) to harvest light, commencing with cyclometallated ruthenium(II) complexes and bis(2,2':6',2''-terpyridine)ruthenium(II) derivatives. We will also focus on electrolyte formulation (containing a redox mediator) and surface and interface treatments. The physics team will initially focus on basic properties of the semiconductor/dye interface using Scanning Probe Microscopy (SPM). Scanning tunnelling microscopy (STM)/non-contact atomic force microscopy (nc-AFM) combined with Kelvin probe force microscopy (KPFM) will provide detailed topographical and electronic information down to the single atom scale. The p-type semiconductor surfaces will be prepared and analysed by these techniques in ultrahigh vacuum and also under ambient conditions in order to achieve controlled adsorption of the dye molecules. The development and optimization of the new dye-complexes and electrolytes based on iterative cycles between the interdisciplinary coworkers also require the use of scanning electrochemical microscopy (SECM) and electrochemical impedance spectroscopy (EIS) to gain insight into how new dye, electrolyte and p-type semiconductor interfaces operate together. This will lead to a fundamental understanding of the chemical and physical processes involved in p-type DSCs, as well as to a sustainable improvement of the device efficiencies.
