The Role of Quantum Dot Size on the Performance of Intermediate Band Solar Cells
… circuit voltage and solar cell efficiency in quantum dot (QD) intermediate band solar cells (IBSCs). More specifically, the effect of indium arsenide (InAs) QD height on the open circuit voltage and solar cell efficiency was studied in a systematic way. To explore this effect in QD solar …

Photophysics of cadmium selenide quantum dot solids
Semiconductor quantum dots or nanocrystals have size dependent optical and electronic properties that arise from quantum confinement. While the quantum size effect is reasonably well understood, the effect of abrupt interface between the nanocrystal and its dielectric environment is not. In this …

Charge carrier dynamics in lead sulfide quantum dot solids
Quantum dots, also called semiconductor nanocrystals, are an interesting class of materials because their band gap is a function of the quantum dot size. Their optical properties are not determined solely by the atomic composition, but may be engineered. Advances in quantum dot synthesis have …

Quantitative Carrier Transport in Quantum Dot Photovoltaic Solar Cells from Novel Photocarrier Radiometry and Lock-in Carrierography
Colloidal quantum dots (CQDs) are promising candidates for fabricating large-scale, low-cost, flexible, and lightweight photovoltaic solar cells. However, their power conversion efficiency is still insufficient for commercial applications, partly and significantly, due to the not-well-understood …
