(Privately Held; Oil & Energy industry)
2008 — 2009 (1 year )
• One of lead engineers responsible for planning of experiments, data interpretation, and failure analysis in R&D module fabrication runs; evaluated module performance against milestones and communicated findings to R&D
• Worked closely with silicon process and laser scribing engineers to develop understanding of the process flow; designed and implemented experiments with custom test structures to isolate corresponding effect on overall module performance.
• Developed measurement and analytical fitting techniques for characterizing device parameters in the small-cell level, as well as characterization and circuit modeling in the module level to understand effects due to non-uniformity.
• Worked with NREL to develop testing methodology for multi-junction solar cells; collaborated with external vendor to develop multi-source solar simulator to expand in-house testing capability.
