Renewable Energy Materials and Devices Lab
We are an interdisciplinary research team at Arizona State University led by Professor Nick Rolston.
We study the connection between material degradation in printable thin-film energy materials and devices with the evolution of mechanical and environmental stress. We leverage scalable, open-air deposition methods to fabricate robust energy devices toward the goal of manufacturing. We use thin-film metrologies along with newly developed and custom-built equipment to characterize material properties and reliability on length scales from angstroms to meters.
Our focus is to develop the next-generation of photovoltaics and battery technology using the paradigm of design for reliability.
