And the main cost of it is the production and processing of the crystalline silicon material.
According to the type of semiconductor materials, thin film solar cells can be divided into amorphous and polycrystalline silicon, GaAs, CdTe, CuInSe2 and Organic thin-film solar cells etc..
Light scattering effect was not only related to the size and shape of metallic nanoparticles, but also to the components of substrate materials and other environmental factors.

Many researchers has been concerning and researching corrosion properties of materials under tension stress states.
It believes that tension stress can significantly increase the corrosion rate of material, and accelerate the material failure [1-3].
And surface of materials generates clear cracks under the bigger stress.

Measurement of Tribological Parameters Eva Labašová a, Rastislav Ďuriš b Slovak University of Technology in Bratislava, Faculty of Materials Science and Technology in Trnava, Institute of Production systems and Applied Mechanics, Paulínska 16, 917 24 Trnava, Slovak Republic aeva.labasova@stuba.sk, brastislav.duris@stuba.sk Keywords: sliding friction, coeficient of friction, rotational joint, tribology Abstract.
Taking into consideration the possibility that testing materials are not heat conductor, it might be possible to monitor temperature differences of sliding joint by thermo-camera.
Obtained results are represented in the graps, which show changes in the coeficient of friction for various materials.
Materials chosen for external bushings are usually for radial bearings.
In other tests, it is possible to use bushings from other materials eventually the contact surfaces of sliding joint innovate by layers, which regenerate the tribological functions of the surface.
