Thin Barrier

The results of the presented studies demonstrate the possibility of using two and three component solid solutions, based on elements of the A3B5 groups, as thin barrier layers to cover an array of structured InAs quantum dots for photoactive heterointerfaces of solar energy. When using three-component solid solutions for QD barrier layers, a decrease in the thermionic generation in the near infrared spectrum and a decrease in the dark current of the heterointerface are obtained.

The optical properties of carbon doped titanium oxide TiO2 were studied. The specimen prepared by utilizing spray pyrolysis method. The absorption coefficient, extinction coefficient, direct, indirect band gap, Urbach’s energy and high-frequency dielectric consistent with real and imaginary were investigated in the optical absorption spectral range of 200-1000 nm. The results showed the carbon is influenced TiO2 and has a semiconductor behavior; the energy gap was 3.15 eV of indirect transition and 3.2 eV for direct transition. The examination for the influence of TiO2 was an extension on the microstructure of carbon and it has an electrical behavior of the composite was distinguished. The modification of the substance structure of carbon by TiO2 doping permits photocatalytic movement of carbon towards the visible light and near infrared (NIR); this doped was gotten in a dry place at ambient temperature and its effect was expected from the physical properties of the energy gap, the advantages exhibited high absorption for spectral selective coating surfaces for operation by utilizing this coating on flat plate collector to give a high absorptivity from the solar energy respect to the incidence solar radiation.
