“…Figure 3 shows a comparison of the absorption coefficients and internal quantum efficiencies of In 0.2 Ga 0.8 Sb (band gap of 0.63 eV) and In 0.53 Ga 0.47 As (band gap of 0.74 eV) cells in the spectral range of 0.5 and 2.5 mm with a p-on-n type configuration. The optical constants for In 0.2 Ga 0.8 Sb are obtained from the published literature (Becker et al, 1961;Gonzalez-Cuevas et al, 2006;Willardson and Beer, 1966) while those for In 0.53 Ga 0.47 As are obtained from Coutts and Benner (1995) and Dinges et al (1992). Note that the absorption coefficient for both In 0.2 Ga 0.8 Sb and In 0.53 Ga 0.47 As decreases sharply beyond their band gaps.…”

SUMMARYFast depleting reserves of conventional energy sources has resulted in an urgent need for increasing energy conversion efficiencies and recycling of waste heat. One of the potential candidates for fulfilling these requirements is thermophotovoltaic (TPV) devices. TPV devices generate electricity from either the complete combustion of different fuels or the waste heat of other energy sources, thereby saving energy. The thermal radiation from the emitter is incident on a TPV cell, which generates electrical currents. Applications of such devices range from hybrid electric vehicles to power sources for microelectronic systems. Absence of any moving parts and versatile fuel usage has made TPV devices very appealing for military and space applications. However, the presently available TPV systems suffer from low conversion efficiency. A viable solution to increase their efficiency is to apply microscale radiation principles in the design of different components to utilize the characteristics of thermal radiation at small distances and in microstructures. In order to have a clear understanding of microscale radiation and its role in TPV devices, several critical issues are reviewed in the present work. Emphasis is given to the development of wavelength-selective emitters and filters and the aspects of microscale heat transfer as applied to TPV systems. Recent progress, along with challenges and opportunities for future development of TPV systems are also outlined.

“…Organic semiconductors have the potential to play a key role in future nanoelectronic devices. [1,2] Various applications of thin organic semiconductor films, like solar cells organic photovoltaic cells (OPVCs), [3][4][5][6] photo-sensors, light-emitting diodes organic light emitting diodes (OLEDs), [7][8][9] (highlights in Condensed Matter Physics and Materials Science) and transistors [10][11][12] are already realized in commercially available devices. However, the fundamental mechanisms behind their opto-electronic properties are currently not fully understood.…”

Structural and optical properties of isolated perylene-3,4,9,10-tetracarboxylic acid dianhydride molecules adsorbed on (100) oriented NaCl and KCl surfaces were studied theoretically to analyze the recently observed red-shift of the optical excitation spectrum after adsorption (Müller et al., Phys. Rev. B, 2011, 83, 241203; Paulheim et al. Phys. Chem. Chem. Phys., 2013, 15, 4906). The ground-state structures were obtained by periodic dispersion-corrected density functional theory (DFT) calculations. For the excited-state calculations, nonperiodic time-dependent DFT methods were applied for a cluster model embedded in point charges. The range-separated hybrid functional CAM-B3LYP was used. Correlation-consistent basis sets were used and the calculated excitation energies were extrapolated to the complete basis set limit. The shift of the first optical excitation energy was analyzed in terms of electronic and geometric contributions. It was found that both the distortion of the molecule due to the interaction with the surface and the electrostatic potential of the surface play an important role.

“…The availability of wide bandwidth optical detectors enabled experimenters to utilize optical heterodyne methods [86] in scattering measurements on sufficiently long-lived plasmas, with lasers that operated quasi-continuously. The scattered radiation could be mixed with either the diffracted edge of the main laser beam ('homodyne'), or with an optical local oscillator beam ('heterodyne') on the surface of a nonlinear detector.…”
