The low-frequency electron absorption spectra in thin films of Cs(Ag₁₋ₓCuₓ)₂l₃ solid solutions have been investigated. At the fundamental band edge, two exciton bands A₀ and A₁ are observed, and the parameters thereof (spectral position, half-width and oscillator strength) have been found in the 0≤x...
