Solar photovoltaics have the potential to make a large contribution to solving the problem of waney fossil fuels and climate change. Recent improvement in solar energy systems leads scientists to develop new materials which can help to increase the efficiency of sunlight harvesting and trapping of solar energy inside of solar cell. Silver nanoparticles in this work were produced by chemical reduction method. AgNO3 10-2 M, 1% and 5% C 6H5O7Na3 aqueous solutions were used in silver nanoparticles synthesis. Plasmonic properties of silver nanoparticles were investigated by UV/VIS spectrometer AvaSpec-2084. Size of silver nanoparticles in colloids were predicted by Mie theory and determined by atomic force microscope NT 206. The influence of silver nanoparticles to solar cells efficiency was experimentally evaluated on handmade experimental stand. It was found that efficiency of solar cells, modified by silver nanoparticles, increased by 10-15%.
