This work elucidates the role of natural membrane confinements of photosystem I complexes (PSI) in light-induced charge separation by comparing the photocurrents of isolated PSI with PSI encapsulated within solid-supported lipid bilayers on electrodes. Our results indicate the critical role of the microenvironment alterations in achieving enhanced photocurrent and stability.
