Nanofluidic Photoionic Membranes for Light Energy Harvesting and Conversion

Light energy harvesting and conversion are essential for addressing the global energy crisis. Inspired by the photoinduced energy conversion processes in biological systems, artificial nanofluidic membranes were developed with photoresponsive properties as ion transport media to harvest light, undergo various responses (cleavage, isomerization, and excitation), and ultimately build potential energy (chemical or electric) and ion-transport induced electron transfer (the origin of electricity). This review summarizes recent advances in photoionic membranes for solar-electric energy conversion, including photoactive materials, fabrication of membranes, and analysis of their energy conversion performance combined with some biomimetic features, e.g., anticoncentration gradient ion pumping and alternating ion transport. Current progress, challenges, and insights for future development are also discussed at the end.
