QESST is developing the knowledge, technology, and engineered systems to provide continued improvement in the efficiency, economic viability, and sustainability of photovoltaic (PV) systems. To this end, QESST is committed to research that spans the three leading commercial PV technologies: silicon, thin films, and tandem devices. More importantly, QESST is blurring the traditional lines between technologies by recognizing and exploiting their commonalities.
This research is organized into three complementary thrusts—Terawatt-Scale Silicon Photovoltaics, Tandem Integration with Silicon Technologies, and Fundamentals for High Efficiency Photovoltaics—and three demonstrative testbeds—Student-Led Pilot Line, Advanced Modules and Integration and Sustainability of Terawatt Photovoltaics. In addition, two themes—Sustainability and Education Research—permeate all areas of QESST research.
