About SDLE

Lifetime and Degradation Science

In its 2010 Science For Energy Technology workshop, the U.S. Department of Energy Basic Energy Sciences program identified photovoltaic module lifetime and degradation science as an energy research priority. Researchers at the SDLE Center build on years of solar PV industry experience to address this priority, engaging students and industry partners in dynamic research programs that move beyond basic qualification testing of systems to determine actual degradation mechanisms and rates – the scientific underpinning of reliability and qualification standards.

By facilitating this collaborative, applied scientific exploration, the SDLE Center pushes the boundaries of lifetime and degradation science to enable the design of better, longer-lasting materials and systems, and accelerated more accurate testing protocols.

Crosscutting Applications

Focusing on solar PV building envelope and energy efficiency technologies, the lifetime and degradation science research at the SDLE Center has broader applications to all materials. The advanced exposure techniques, rigorous evaluation processes, and quantitative degradation rate modeling performed at the Center connect materials, components, and systems to address crosscutting research challenges not only for PV but for all environmentally exposed technologies.
