Quantum 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 کاملAll-solution-processed PbS quantum dot solar modules.
A rapid increase in power conversion efficiencies in colloidal quantum dot (QD) solar cells has been achieved recently with lead sulphide (PbS) QDs by adapting a heterojunction architecture, which consists of small-area devices associated with a vacuum-deposited buffer layer with metal electrodes. The preparation of QD solar modules by low-cost solution processes is required to further increase...
متن کاملQuantum-Dot-Sensitized Solar Cell with Unprecedentedly High Photocurrent
The reported photocurrent density (J(SC)) of PbS quantum dot (QD)-sensitized solar cell was less than 19 mA/cm(2) despite the capability to generate 38 mA/cm(2), which results from inefficient electron injection and fast charge recombination. Here, we report on a PbS:Hg QD-sensitized solar cell with an unprecedentedly high J(SC) of 30 mA/cm(2). By Hg(2+) doping into PbS, J(SC) is almost doubled...
متن کاملSemiconductor quantum dot-sensitized solar cells
Semiconductor quantum dots (QDs) have been drawing great attention recently as a material for solar energy conversion due to their versatile optical and electrical properties. The QD-sensitized solar cell (QDSC) is one of the burgeoning semiconductor QD solar cells that shows promising developments for the next generation of solar cells. This article focuses on recent developments in QDSCs, inc...
متن کاملSolution processed flexible and bending durable heterojunction colloidal quantum dot solar cell.
A flexible hybrid heterojunction PbS colloidal quantum dot solar cell, where the photoactive layers are deposited using a solution processed fabrication approach under ambient condition and at room temperature is presented. The bending stability of the obtained solar cell is evaluated. The results show that the solar cell exhibits high bending stability and even under the bent state the cell al...
