“…The efficiency was found to be around 0.99 % and other solar cell parameters for the CdS QDSSCs are shown in Table 1. Previously, an efficiency of 0.69 % was obtained for a single layer CdS-QD/ZnO-based solar cell as reported by Chen et al [14]. Thus, the fabricated QDSSC displayed higher efficiency.…”

High cost conducting metals such as Au or Pt are generally used as counter electrodes in quantum dot sensitized solar cells. In this article, we report working of a CdS quantum dot sensitized ZnO thin film solar cell, having FTO as working electrode and aluminium as counter electrode.The CdS quantum dots are prepared by simple low cost chemical technique and characterized by absorption spectroscopy, X-ray diffraction, atomic force microscopy and high resolution trans electron microscopy. These quantum dots are used as an active layer in a solar cell and current density-voltage characteristic of the solar cell is obtained under white light illumination and dark conditions.

“…The temperature dependence of charge carrier effective masses in PbTe is well studied. [31][32][33] We determined the conductivity effective masses of holes and electrons from the electronic bandstructure calculations. The general assumption of parabolic energy bands does not hold for lead telluride.…”

Articles you may be interested in Towards a predictive route for selection of doping elements for the thermoelectric compound PbTe from firstprinciples J. Appl. Phys. 117, 175102 (2015) We determined the temperature effects on the electronic properties of lead telluride (PbTe) such as the energy bandgap and the effective masses of charge carriers by incorporating the structural changes of the material with temperature using ab-initio density functional theory (DFT) calculations. Though the first-principles DFT calculations are done at absolute zero temperatures, by incorporating the lattice thermal expansion and the distortion of Pb 2þ ions from the equilibrium positions, we could determine the stable structural configuration of the PbTe system at different temperatures.
