A quantum dot solar cell (QDSC) is a solar cell design that uses quantum dots as the captivating photovoltaic material. It attempts to replace bulk materials such as silicon, copper indium gallium selenide (CIGS) or cadmium telluride (CdTe). Quantum dots have bandgaps that are adjustable across a wide range of energy.

AI Customer ServiceA quantum dot solar cell (QDSC) is a solar cell design that uses quantum dots as the captivating photovoltaic material. It attempts to replace bulk materials such as silicon, copper indium gallium selenide (CIGS) or cadmium telluride (CdTe). Quantum dots have bandgaps that are adjustable across a wide range of energy levels by changing their size.
There are two possibilities for multiple exciton generation in quantum dot sensitized solar cells utilizing the hot electrons. In one case, cooling of hot carriers needs to be prolonged enough e.g. more than 10 ps to utilize hot carrier using interfacial carrier transfer.
Quantum dot sensitized solar cells have already made progress in photovoltaic efficiency from less than 1% to 12% or more over the years.
Although a practical application of quantum dot solar cells has yet to be achieved, a large number of theoretical calculations and experimental studies have confirmed the potential for meeting the requirement for ultra-high conversion efficiency.
In 2006, V. I. Klimov calculated detailed balance efficiency for quantum dot absorber based solar cells (Klimov, 2006) and is shown in Fig. 4. Here also a strong dependence on band gap of absorbing quantum dot material is observed for detailed balance efficiency.
In the search for a third generation of solar-cell technologies (as a follow-up to silicon and thin-film solar cells), a leading candidate is the use of “quantum dots”—iny spheres of semiconductor material measuring only about 2–10 billionths of a meter in diameter.
