Colloidal quantum dots have emerged as a material platform for low-cost high-performance optoelectronics. At the heart of optoelectronic devices lies the formation of a junction, which requires the intimate contact of n-type and p-type semiconductors. Doping in bulk semiconductors has been largely deployed for many decades, yet electronically active doping in quantum dots has remained a challen...

A significant Au particle size-dependent electrocatalytic effect has been shown in a sandwich type photoelectrochemical solar cell consisting of CdS quantum dot (QD)-sensitized TiO(2) photoelectrodes, Au nanoparticle (NP)-loaded SnO(2) counter electrodes, and a polysulfide electrolyte solution intervening between the electrodes.

In this paper, we have calculated the efficiency and I-V characteristic of a Quantum Dot (QD) Solar Cell (SC) based on multi-stacked different-sized InGaN QDs on GaN substrate. In order to engineering the confinement states of QDs, we have inserted differentsized QDs in i-region of a p-i-n structure which includes different layers. This leads to Rainbow SCs.

Quantum Dot Solar Cells In article number 2202994, Yana Vaynzof and co-workers report on a strategy to eliminate excess lead halide species from the interdot spacing of sulfide quantum dot solar cells. This process significantly enhances coupling, resulting in improved efficiency stability photovoltaic devices.

For the application of colloidal semiconductor quantum dots in optoelectronic devices, for example, solar cells and light-emitting diodes, it is crucial to understand and control their charge transport and recombination dynamics at high carrier densities. Both can be studied in ambipolar, light-emitting field-effect transistors (LEFETs). Here, we report the first quantum dot light-emitting tran...

Abstract In the present paper hybrid core–shell InP/ZnS quantum dots were prepared by one pot synthesis method which does not require additional component injections and complies more with cost requirements. The synthesized characterized X-ray diffraction optical spectroscopy methods. applicability of particles in inverted solar cells fabricated a step-by-step procedure combines thermal vacuum ...
