The present work is devoted to studying photoelectrical properties of the solar cells covered with nickel oxide nanoparticles synthesized in counter flow propane flame. In the given case, the nanoparticles of oxides play the role of quantum points on the surface of the solar cells and promotes effective absorption of light energy. The applying of silicon solar cells of nickel oxide nanoparticles to the surface caused the increase of output open circuit voltage of 4-7 %, the increase of short - circuit current of 20 - 28 %, that in total caused the increase of efficiency of the solar cells by 2-3%.

In this paper we present a study of the formation of soot, which has the properties of the superhydrophobic surface of a silicon substrate. Found that the soot content in the putty from 1 to 8% increase in the hydrophobic properties of plaster.
