Solar cells using quantum funnels.
Colloidal quantum dots offer broad tuning of semiconductor bandstructure via the quantum size effect. Devices involving a sequence of layers comprised of quantum dots selected to have different diameters, and therefore bandgaps, offer the possibility of funneling energy toward an acceptor. Here we report a quantum funnel that efficiently conveys photoelectrons from their point of generation tow...
متن کاملInAs/GaAs Quantum Dot Solar Cell
In this work Silvaco TCAD have been used to model quantum dot solar cell. It was found that the addition of InAs QD(quantum dot) in the intrinsic layer of hetero-structure InGaP/GaAs p-i-n solar cell extends the absorption range of the solar cell, thereby giving rise to efficiency enhancement of the QD solar cell by 3.8851 % it was also observed that the fill factor increases from 83.2724% to 8...

Advanced concepts for high efficiency solar cells such as hot carrier effects, Multi-Exciton Generation (MEG), and Intermediate-Band (IB) absorption in low-dimensional nanostructures are under focused research topics in recent years. Among various potential approaches, this chapter is devoted to the device physics and development of the state-of-the-art technologies for quantum dot-based IB sol...
متن کاملQuantum Dot Sensitized Solar Cells
In response to rapidly increasing global energy demand, the development of alternative energy sources to fossil fuels has emerged as one of the most urgent technological challenges. Solar energy, which represents a nearly unlimited source of clean power, has been considered as one of the most promising new energy sources. In addition to the current success of silicon based solar cells, quantum ...
متن کاملQuantum Dot Solar Cells: Preprint
Quantum dot (QD) solar cells have the potential to increase the maximum attainable thermodynamic conversion efficiency of solar photon conversion up to about 66% by utilizing hot photogenerated carriers to produce higher photovoltages or higher photocurrents. Three quantum dot solar cell configurations are described.
