The paper presents is devoted to such a topical area of modern electronics as obtaining solar energy, as well as the creation of high-performance wide optical range sensors. To solve this problem, we studied the effect of Ni-containing clusters obtained by diffusion of P and Ni in P-Si on the efficiency of solar cells. Diffusion of P and Ni is performed by pulsed photon irradiation and thermal heating for comparison. During PPI in semiconductors, in the process of light absorption, in addition to thermal heating, there are a number of other important factors, such as the concentration of generated antibonding electron-hole pairs, selective absorption on impurities and defects, change of their charge state and others. These factors, in our opinion, play an important role in the photostimulated diffusion process. As a result, by using the PPI method on the basis of Si, solar cells were obtained, the efficiency of which was 4% higher than the solar cells obtained by thermal diffusion.
