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 levels by changing their size.
The incorporation of quantum dots into photovoltaics results in theoretically high thermodynamic conversion efficiencies of up to 40%, but in practise, the efficiencies are lower than those of dye-sensitized solar cells.
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.
The first report on the efficiency of Quantum Dot Sensitized Solar Cells (QDSSCs) was 0.12%. As of today, the efficiency is reported as 18.1 %, and further, the researchers are working to improve the efficiency of QDSSCs. 1. Introduction Energy is an essential part of modern life, leading to ever-increasing consumption across the world.
