Various forms of the silicide NPs are investigated for thermoelectric conversion energy and the Ge NPs formation is studied for optoelectronic applications. A thin layer of Si:H was deposited on different substrates by d chemical deposition (PECVD). The self-forming silicides NPs were realized during evaporation of Magnesium and Calcium, the Ge NPs was performed by molecular beam epitaxy (MBE) at substrate temperatures from 300 to 450 ° C. The NPs self - forming was investigated by SEM, TEM, AFM and Raman spectroscopy. The increase of optical absorption needed for the photovoltaic applications has been confirmed by the photothermal deflection spectroscopy (PDS). The optical and optoelectronic properties in the infrared part of the spectrum were investigated by the photoluminescence and electroluminescence.
