The fundamentals of record Tc superconductivity (Tc 〰 203K(!)) discovered recently under high pressure in sulfur hydrides will be discussed. Because of complex spectrum, the usual methods of evaluating
Tc are not applicable. One can develop a novel method allowing to study the behavior of Tc and to determine the relative contribution of optical and acoustic modes. The remarkable feature of the phase diagram is a drastic increase in the value of Tc from Tc 〰 100K to Tc 〰 200K caused by a relatively small change in pressure near P〰 120GPa. Future developments leading to higher values of Tc , potentially up to room temperature, will be also discussed.
