چکیده

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 deposition spin-coating techniques was investigated. resulting efficiency cell is comparable to that quantum-dot sensitized TiO 2 based cells. Therefore, can be considered as multifunctional light-harvesting materials useful for implementation different types photovoltaic devices, such dot

Quantum Dots: Theory, Application, Synthesis

Semiconductor crystals smaller than about 10 nm, known as quantum dots, have properties that differ from large samples, including a bandgap that becomes larger for smaller particles. These properties create several applications for quantum dots, including efficient solar cells and qubits for quantum computing. Various synthesis procedures have been proposed and implemented, including chemical s...

Synthesis and Optical Study of CdZnTe Quantum Dots

The comparison of growth processes and fluorescent properties of CdZnTe semiconductor quantum dots that are synthesized in different concentrations of Zn2+ in water are discussed in this paper. The samples are characterized through absorbtion (UV) and photoluminescence spectra (PL). The results show that when the reaction time is prolonged, the absorption peak and fluorescent emission peak pres...

Photovoltaic and rectification currents in quantum dots

We investigate theoretically and experimentally the statistical properties of dc current through an open quantum dot subject to ac excitation of a shape-defining gate. The symmetries of rectification current and photovoltaic current with respect to applied magnetic field are examined. Theory and experiment are found to be in good agreement throughout a broad range of frequency and ac power, ran...

Photovoltaic performance of ultrasmall PbSe quantum dots.

We investigated the effect of PbSe quantum dot size on the performance of Schottky solar cells made in an ITO/PEDOT/PbSe/aluminum structure, varying the PbSe nanoparticle diameter from 1 to 3 nm. In this highly confined regime, we find that the larger particle bandgap can lead to higher open-circuit voltages (∼0.6 V), and thus an increase in overall efficiency compared to previously reported de...
