Earlier we have proposed a new approach to the analysis of superconductingphase diagrams for cuprates and pnictides and have shown that the positions ofsuperconducting domes on the diagrams can be predicted with high accuracyproceeding from only the crystal structure of a particular compound. Theproposed approach uses the concept of the self-localization of doped carriersdue to their formation of trion complexes that represent a bound state of thedoped carrier and charge transfer excitons emerging under its influence. Here,as exemplified by cuprates, we show that the use of the proposed approach tothe analysis of the transformation of an electronic structure with dopingenables an explanation to a range of their anomalies: Fermi arcs, large andsmall pseudogaps etc. The basic conclusion is that the role of the Fermisurface in cuprates is played by an isoenergetic contour that emerges at thesectioning of the surface of a band dispersion by a dispersionless "biexciton"pair level. This level additionally plays the role of an acceptor to lead tothe emergence of hole carriers on the isoenergetic contour and to a jump of thechemical potential. Based on the conducted consideration, we propose a possiblemechanism of superconducting pairing genetically inherent in such a system.
