Tillandsia species with degenerated roots have evolved into hygroscopic leaves that absorb moisture from air.T his interesting biological adaptability has inspired us to develop an integrated hygroscopic photothermal organogel (POG) to achieve asolar-powered atmospheric water harvesting (AWH). The well-designed hydrophilic co-polymeric skeleton is fabricated to accommodate hygroscopic glycerin medium, which enables the POG self-contained property, mechanically flexibility and synergistic enhancement of moisture sorption. The integration of interpenetrated photothermal component of poly-pyrrole-dopamine (P-Py-DA) can endow the POG an efficient solar-to-thermal property for controllable solar-driven interfacial water releasing.T he integrated POG has an equilibrium moisture sorption of 16.01 kg m À2 at the RH of 90 %, and daily water production as high as 2.43 kg m À2 day À1 is achieved in actual outdoor experiments.
