The idea of using quantum dots as a path to high efficiency was first noted by Burnham and Duggan in 1989. At the time, the science of quantum dots, or "wells" as they were known, was in its infancy and early examples were just becoming available. Another modern cell design is the dye-sensitized solar cell, or DSSC. DSSCs use a sponge-like layer of TiO 2 as the semiconductor valve as well as a mechanical support structure. During cons
