Popis:	The transformation of the long-wavelength edge of the external quantum exit (EQE) formation mechanisms in textured silicon solar cells (SCs) is revealed, depending on their thickness. Expressions for experimental EQE dependences on the long-wavelength absorption edge are obtained for a wide range of base thicknesses (100-450 {\mu}m). The expressions allow optimal SC base thickness values calculation from the condition of maximal photoconversion efficiency taking into account surface recombination velocity. In particular, it was found that optimal 100-{\mu}m base thickness corresponds to the surface recombination velocity of about 3 cm/s. Comment: In Russian, 10 pages, 3 figures
