The features of light absorption and localization in one-dimensional chirped photonic crystals (PCs) are studied. It is shown that although chirping leads to the loss of ideal periodicity, the integral over a wide spectral region light energy density practically does not change. We have shown that violation of the ideal periodic structure (chirping) can not only decrease the integral in the broad spectral region absorption, but also lead to an increase in this absorption in the PC, and this depends on the form of chirping and the form of modulation of the imaginary part of the dielectric permittivity. A study of the evolution of the absorption spectra when the chirping contrast is changed showed that at certain values of the chirping contrast, mini-zones of transmission appear in the photonic band gap, where significant absorption is observed.
