The pseudocubic approach is a new strategy to realize good electronic transport properties and a high thermoelectric figure of merit zT in non‐cubic chalcopyrites through the utilization of cubic‐like degenerate electronic bands, via the coexistence of a long‐range cubic framework with short‐range non‐cubic lattice distortions.
