New reaction and electrolyte media for inorganic synthesis and solar cells (»Add to Infobox)

Research Leader: Professor Lars Kloo
Viktor Johansson, Alan Snedden, Ze Yu, Josefin Åkerstedt


Inorganic Chemistry

The project is divided into two distinct sub-projects.

The first sub-project is of intra-scientific character and devoted to the study of clusters and low-dimensional compounds, embracing both the development of new methods of synthesis, preferably operating at ambient conditions, structural analyses of liquid reaction media and solid products by means of vibrational and multinuclear NMR spectroscopy and X-ray scattering, diffraction and EXAFS, as well as characterisation of physical properties by conductivity measurements and quantum chemical calculations. Ambient media for synthesis are based both on extreme Lewis acidic and basic systems, as well as ionic liquids. The overall aim is the controlled synthesis of new materials with special physical properties based on knowledge about the fundamental co-ordination chemistry and chemical bonding of the reactants and structure fragments in the media of synthesis and in the solid products obtained.

The second sub-project includes the design and characterisation of new materials for photoelectrochemical solar cells. In parts, the media and tools overlap with the first sub-project. Special attention is paid to the introduction of new ionic liquids and solid hole conductors as electrolytes in photoelectrochemical solar cells, aiming at enhanced long-time stability and increased efficiency. Also, the electrolyte-electrode interface structures and reactions are studied.
