The BCS (Bardeen–Cooper–Schrieffer, 1957) theory of superconductivity suggests that there is room for higher superconducting critical temperatures (Tc) in metals composed of light elements (such as hydrogen). Materials with reasonably high values of a characteristic phonon frequency and of the electron-phonon coupling constant are favorable for the search for a higher Tc. The recently discovered record Tc of 203 K in hydrogen sulfide at 155 GPa confirmed a major result of the theory for conventional superconductors that there is no apparent limits to Tc.
