Biomimicry designs for photoelectrochemical systems: Strategies to improve light delivery efficiency

In the past years, photoelectrocatalysis has been developed to offer green and sustainable application wastewater remediation, water disinfection, H 2 production CO reduction. The advances of these systems with new semiconductor photoelectrocatalysts that are photoexcited visible light giving photogenerated charge carriers efficiently, separated in a photoelectrochemical cell, explained. These studies do not consider transport as fundamental aspect light–matter interaction, although harvesting photons at surface limits quantum yield by existing architectures. This opinion review envisages biomimicry an alternative natural guide for synthesizing more efficient photoelectrodes. Micro- nanostructure shapes from nature identified prepare bio-inspired photoelectrodes reactors indispensable element. implementation strategies phototroph organisms maximize adsorption enhancement photoelectrocatalytic area analyzed key factors such bio-based
