"CdTe Photovoltaics High Efficiency & Low Cost as Multi GS Scale"
Part of the Fall 2018 Graduate Seminar Series
Over the past two decades, photovoltaics (PV) have successfully transitioned from an expensive, niche product into a low cost, high volume renewable energy source that is cost competitive with fossil fuel energy sources. At present, the PV market is dominated by crystalline Silicon-based modules. First Solar, the largest PV company in the United States, with a large manufacturing footprint in the Midwest, uses a unique, thin film, CdTe-based PV technology that is inherently low cost and requires much less energy and water to produce. Historically, the efficiency of CdTe PV has traditionally lagged Si PV. Over the past six years, fundamental Materials and Chemistry breakthroughs in CdTe PV have closed the efficiency gap with Si PV. Moreover, recent advancements in CdTe PV have shown great promise towards further increases in efficiency, thereby helping to maintain CdTe as low cost, high efficiency PV product for the future.
