- Quantum_dot_solar_cell abstract "Quantum dot solar cells are an emerging field in solar cell research that uses quantum dots as the absorbing photovoltaic material, as opposed to better-known bulk materials such as silicon, copper indium gallium selenide (CIGS) or CdTe. Quantum dots have bandgaps that are tunable across a wide range of energy levels by changing the quantum dot size. This is in contrast to bulk materials, where the bandgap is fixed by the choice of material composition. This property makes quantum dots attractive for multi-junction solar cells, where a variety of different bandgap materials are used to improve efficiency by harvesting select portions of the solar spectrum.The potential benefits of the quantum dot approach has led to widespread research in the field. Early examples used costly molecular beam epitaxy processes, but alternative inexpensive fabrication methods have been developed. These attempts rely on quantum dot synthesis using wet chemistry (colloidal quantum dots – CQDs) and subsequent solution processing of quantum dots. Using this approach, concentrated nanoparticle solutions are made stable by long hydrocarbon ligands which keep the nanocrystals suspended in solution. When a quantum dot solid is ready to be made, these solutions are cast down and the long stabilizing ligands are replaced with short-chain crosslinkers. Recent efforts have used chemical engineering at the nanocrystal surface to better passivated the nanocrystals and reduce detrimental trap states which would curtail device performance by means of carrier recombination. These cells result in an efficiency of 7.0% which is among the highest observed for QDSCs and, although quite low compared to that of commercial bulk silicon cells (about 17%), it has a potential for improvement beyond silicon cells by means of hot carrier extraction and efficient multiple exciton generation.".
