We predict that superconductivity in mesoscopic thin films can be stabilized in high magnetic fields if the superconductor is driven out of equilibrium by a DC voltage bias. For realistic material parameters and temperatures, we show that superconductivity is restored in fields many times larger than the Chandrasekhar-Clogston limit. After motivating the effect analytically, we perform rigorous numerical calculations to corroborate these findings and present concrete experimental signatures. On the technical side, we also introduce a formulation of the nonequilibrium kinetic equations that both generalizes and simplifies previous results.
