Responsibilities
Dr. Schujman, as the manager of the PVMC Metrology program, communicates with the PVMC members to execute industry proposed metrology initiatives. She is focused on metrology and characterization projects that need to be resolved to advance the goals of the DOE SunShot Initiative. Her responsibilities include industry collaboration for project definition, proposing technical and strategic approaches, establishing milestones and budgets, project execution and report to PVMC members.
Typical metrology projects include the development of metrology platforms for performance characterization of solar cells and modules tailored to CIGS-based photovoltaics as well as the evaluation and introduction of metrology techniques apt for use as in-line or in-situ/real-time monitoring and, process control. These techniques are applied in the deposition systems at the Manufacturing Development Facility (MDF) located at the CNSE Solar Energy Development Center in Halfmoon, NY with manufacturing capacities exceeding 10MW.
