The article is devoted to the presentation and discussion of the primary results of an experimental study of the possibility of using the modern "transient photoconductance method" and "noncontact quasi-steady state photoconductivity method" for a more accurate, accelerated and nondestructive determination of the lifetime of charge carriers in silicon wafers, intended as a base material for the manufacture of high-speed p-n-microelectronic devices and high-performance solar cells. It is shown that the method of quasi-stationary photoconductivity is based on the following principles: illumination of the research object with a long, slowly decaying light pulse; simultaneous measurement of sample surface conductivity and incident light intensity as functions of time; determining the level of generation of electron-hole pairs in the semiconductor material from the measured value of the intensity of the incident light at each moment of time; determination of the quasi-equilibrium concentration of charge carriers, based on the measured value of the surface conductivity at each moment of time; calculation of the effective lifetime of minority charge carriers in the quasi-equilibrium approximation.
