A scientist working at the University of Texas at Arlington is developing novel synthetic materials that can enhance inorganic metal oxides for utilisation in a range of energy-saving applications.
Robin Macaluso, an associate professor of chemistry and biochemistry, recently obtained a two-year, $250,000 grant from the National Science Foundation’s (NSF) Division of Materials Research to fund the research. Macaluso is the principal investigator of the project, titled: ‘New Oxysulfide Perovskites for Photocatalytic and Photovoltaic Applications.’
Solar energy technology
The objective of the research is to create novel materials that are capable of making a positive impact in solar energy technology, and consequently can be utilised to meet the ever-growing necessity for dependable sources of alternative and greener energy.
The study will be centred around establishing a new technique for developing synthetic versions of sulphide and oxysulphide perovskites. (Perovskites are a group of materials that share an unusual crystalline structure and chemical formula.) This material would then behave as a semiconductor that transfers the electric charge that it has generated when light hits it.
Oxide perovskites are the most prominent and ubiquitous perovskites due to the fact they are stable and typically comprised of extremely plentiful elements. However, they are not usually semiconductors. The predominant difficultly with this method is being able to control semiconducting behaviour whilst preserving the stability and utilisation of abundant, non-toxic elements, Macaluso explained.
