In situ synchrotron X‐ray diffraction is used to investigate a three‐way piezo‐phototronic soft material. This new system is composed of a semi‐crystalline poly(vinylidene fluoride‐ co ‐trifluoroethylene) piezoelectric polymer and titanium oxide nanoparticles. Under light illumination, photon‐induced piezoelectric responses are nearly two times higher at both the lattice‐structure and the macroscopic level than under conditions without light illumination. A mechanistic model is proposed.
