AbstractA vacuum evaporation technique has been used to produce thin, optical quality films of samples of Type II kerogen and of insoluble organic residue from the Murchison meteorite. Using these films, optical constants have been measured from 0.15 to 40 μm for kerogen, and from 2.5 to 40 μm for the Murchison residue. The infrared absorption properties of these materials show many similarities, although Murchison residue is more opaque throughout the infrared than is kerogen, and shows no distinct aliphatic absorptions.

In this study, a liquid crystal display LCD cell was prepared. with the windows made from a thin film of SnO2 add to it Bi2O3 by weight (0,1,3,5,7)% .The effect of adding optical and electrical properties of the cell was studied. The thin film was prepared by vacuum evaporation technique. It was added to use powder mixing technique. The results showed a decrease in the value of the current passing through the cell and  an increase in resistance value from 9.7MΩ to 12.5MΩ. The results also showed an increase in the cell's ability to control the light and darkness it with lower voltages by increasing the add rate. This leads to a decrease power used of a single cell. The value of the capacitance is not affected by the addition of Bi2O3 and  was stable at ( 3nf ±1% ).   http://dx.doi.org/10.25130/tjps.23.2018.175

Thin film solar cells are preferable to the researchers and in applications due to the minimum material usage and to the rising of their efficiencies. In particular, thin film solar cells, which are designed based one transition metal chalcogenide materials, paly an essential role in solar energy conversion market. In this paper, transition metals with chalcogenide Nickel selenide termed as (NiSe2/Si) are synthesized. To this end, polycrystalline NiSe2 thin films are deposited through the use of vacuum evaporation technique under vacuum of 2.1x10-5 mbar, which are supplied to different annealing temperatures. The results show that under an annealed temperature of 525 K, the nickel sulfoselenide thin films are polycrystalline with an efficient regularity and best crystalline quality. In addition, the results demonstrate that the intersection argument for the optical properties under investigation provid the direct bandgap, over which the films have inferred on variety (1.55 and 1.75 eV). Overall, the results illustrate that an efficiency of 2.89% can be achieved with 525 K temperature.
