Higher Efficiency with Quantum Dot Solar Cells

This development offers the possibility of increased efficiency in solar panels, and the technology is able to be manufactured using high-throughput roll-to-roll manufacturing. With the use of quantum dots, photocells could theoretically see as much as a 35 percent increase in power conversion efficiency above contemporary cells. The research cell was constructed as a "layered cell consisting of antireflection-coated glass with a thin layer of a transparent conductor, a nanostructured zinc oxide layer, a quantum dot layer of lead selenide treated with ethanedithol and hydrazine, and a thin layer of gold for the top electrode."
