Our Projects

Some examples of our projects include:

Molecular fingerprinting of chemically complex oxides

Understanding the molecular scale mechanisms governing the degradation of materials used in the fabrication of solar devices and panels is key in developing new materials and/or processes that extend the lifetime of performance and minimize environmental impact. We are using high throughput computational chemistry screening techniques that integrate information on bond geometry and bond chemistry to explore the development of unique chemical fingerprints that relate to chemical reactivity of multicomponent ceramics and alloys that are used in solar cells and panels. 

Informatics based modeling for predictive toxicology

Of major concern is the environmental impact associated with the degradation of solar panels at the end-of-life when disposed of in landfills. We are applying a broad based of statistical learning tools on large and diverse multivariate data of materials properties that are known to be influential in the health hazards associated with degradation of the different materials used in solar panel manufacturing. This has permitted us to develop quantitative models to predict the relative impact of new materials chemistries on toxicity.

Spectroscopic investigation of solar materials

In addition to designing safer materials, ensuring those materials have a long lifetime will minimize the overall environmental impact. As an experimental complement to the computational materials design component, we are investigating different materials using various spectroscopic methods. By measuring structural, vibrational, and energetic fingerprints we can improve the computational screening aspect. This creates a positive feedback loop in which experimental data bolsters the informatics, which better guides and accelerates the materials design process.
