A technology for producing nickel atom clusters in the volume of a silicon crystal lattice with controlled parameters has been developed. Solar cells based on silicon containing nickel atom clusters have been manufactured and their parameters have been determined. It has been established that the presence of nickel atom clusters in the lattice allows for a significant expansion of the spectral sensitivity region of silicon solar cells toward the IR spectrum to 4 μm. A new technological method for producing efficient solar cells (SC) with stable parameters and maximum efficiency has been proposed. Technology of creation of clusters of nickel atoms in the silicon crystal lattice with adjustable parameters was developed. Solar cells based on silicon containing clusters of nickel atoms were developed and their performances were determined. It is found that the presence of clusters of nickel atoms in the lattice allows to significantly broaden the spectral sensitivity region of the silicon cells toward the IR spectrum to 4 microns. A new technological method of manufacturing effective solar cells with stable parameters and maximum coefficient of performance has been revised.
