Ge Quantum Dots

The size of Germanium (Ge) Quantum Dots (GQD’s) in Titanium Dioxide (TiO2) can be tailored, using different techniques like sputtering, laser ablation and sol gel. Similarly the absorption range of Ge may also be broadened in visible and NIR range. We report the use of Ge QD’s to sensitize meso-porous TiO2 film to make quantum dot sensitized solar cells (QDSSC) for the next generation photovoltaics. Ge -TiO2 nano-porous thin films were deposited using rf- planer magnetron sputtering using various ranges of rf-power, Argon pressure and substrate temperature. The fabricated films with various Ge concentrations were studied using X-ray Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), Transmission Electron Microscopy (TEM), High Angle Annular Dark Field Imaging (HAADF) and UV-Visible Spectroscopy (UV-VIS).In the thin film meso-structure the Ge dots were embedded in the TiO2 matrix. The average particle size of Ge quantum dots was determined by HAADF. The solar cell performance has been checked using sun simulator. Experimental ways to improve cell performance are discussed.

The Way

The electrophilic borylation of 2,5-diarylpyrazines results in the formation of boron-nitrogen doped dihydroindeno[1,2-<i>b</i>]fluorene which can be synthesized via mildly air-sensitive techniques and the end products handled readily under atmosphereic conditions. Through transmetallation via diarylzinc reagents a series of derivatives were sythesized which show broad absorption profiles that highlight the versatility of this backbone to be used in organic solar cell devices. These compounds can be synthesized in large yields, in alow number of steps and functionalized at many stages along the way providing a large depth of possibilities. Exploratory device paramaters were studied and show PCE of 2%.

Organic solar cells have potential as an alternative to conventional inorganic solar cell due to low processing cost, flexibility and easy fabrication technique. The goal of this paper is to study the characteristics of the CuPc and PCBM based organic solar cell by introducing a thin layer of Ag at the interface of donor (CuPc) and Acceptor (PCBM), their photovoltaic and optical properties were investigated. The heterojunction solar cells with and without silver inter layer were fabricated through thermal deposition in HR vacuum. The OPV solar cells were characterized using current-voltage graphs, absorbance spectrum and Impedance spectroscopy. Impedance spectroscopy was taken to identify the traps using series resistance, parallel resistance, and Impedance spectrums under different frequencies. Optical behaviors of these devices have been investigated with absorbance spectrum. Introducing Ag to interfacing point produced traps and these traps causes to decreased Voc, Isc, FF, and efficiency. The effect of silver layer at donor acceptor interface was studied.
