1. High Bandgap FAPbBr3 Perovskite Solar Cells : Preparation, Characterization, and Application
Sammanfattning : High bandgap lead-halide perovskite solar cells (PSCs) have gained interest as top cells for tandem solar cells and photoelectrochemical applications due to their suitable energy bands. However, the PSCs have limited stability and performance, and their fabrication in a glovebox and utilization of expensive metal contacts increase the cost and limit their application. LÄS MER
2. Polymers at the Electrode-Electrolyte Interface : Negative Electrode Binders for Lithium-Ion Batteries
Sammanfattning : We are today experiencing an increasing demand for high energy density storage devices like the lithium-ion battery for applications in portable electronic devices, electric vehicles (EV) and as interim storage for renewable energy. High capacity retention and long cycle life are prerequisites, particularly for the EV market. LÄS MER
3. Oxygen formation in the chlorate process and preparation and deactivation of ozone selective anodes
Sammanfattning : This thesis presents experimental studies concerning two differ-ent electrolytic processes. One part deals with the electrochemicalformation of ozone and focuses on the preparation and deactiva-tion of a highly ozone-selective metal oxide anode (NATO - nickeland antimony doped tin oxide).

4. Membrane Electrode Assemblies Based on Hydrocarbon Ionomers and New Catalyst Supports for PEM Fuel Cells
Sammanfattning : The proton exchange membrane fuel cell (PEMFC) is a potential electrochemicalpower device for vehicles, auxiliary power units and small-scale power plants. In themembrane electrode assembly (MEA), which is the core of the PEMFC single cell,oxygen in air and hydrogen electrochemically react on separate sides of a membraneand electrical energy is generated.
