• Solar‐driven interfacial vaporization by localizing solar‐thermal energy conversion to the air−water interface has attracted tremendous attention. In the process of converting solar energy into heat energy, photothermal materials play an essential role. Herein, a flexible solar‐thermal material di‐cyan substituted 5,12‐dibutylquinacridone (DCN−4CQA)@Paper was developed by coating photothermal quinacridone derivatives on the cellulose paper. The DCN−4CQA@Paper combines desired chemical and physical properties, broadband light‐absorbing, and shape‐conforming abilities that render efficient photothermic vaporization. Notably, synergetic coupling of solar‐steam and solar‐electricity technologies by integrating DCN−4CQA@Paper and the thermoelectric devices is realized without trade‐offs, highlighting the practical consideration toward more impactful solar heat exploitation. Such solar distillation and low‐grade heat‐to‐electricity generation functions can provide potential opportunities for fresh water and electricity supply in off‐grid or remote areas. Organic molecule (DCN−4CQA) with the absorbance region at 300–800 nm and photothermal conversion efficiency of 18.2 % under one sun was employed for fabricating flexible photothermal evaporators for solar steam and thermoelectric power generation.
