About this file

This document is a slide presentation summary for a research project funded by the Department of Energy's Durable Module Materials Consortium DuraMAT program. The project aims to investigate interfacial degradation in glass/glass photovoltaic modules through chemical, structural, and mechanical characterization of module interfaces. The goals are to develop adhesion measurement methods for glass/glass modules, demonstrate a time-resolved electroluminescence imaging technique, and provide insights into degradation mechanisms present at glass/glass module interfaces through collection and analysis of degraded samples. The work will be conducted by a team from the National Renewable Energy Laboratory and Stanford Linear Accelerator Center utilizing advanced materials forensics methods. Quarterly progress reports are due on January 7, April 7, July 7, and October 7 for the duration of the project period.

Core Objective & Teaming

DuraMAT | 3

Here we will provide chemical, structural, and mechanical insights that will enable a cutting-edge understanding of the degradation mechanisms present in glass/glass module interfaces

• Collect and generate: G/G panels and MiMos which demonstrate degradation

• Imaging techniques: assess the full modules and narrow-in on regions where degradation is occurring

• Develop: adhesion measurement methods to confirm and quantify the mechanical degradation.

• Characterize: degraded regions will be studied in detail using advanced materials forensics methods to monitor degradation at a fundamental level
