Rational design of bio-hybrid photovoltaic and/or optoelectronic devices requires systematic electrochemical characterizations of photosystem I (PSI), the photosynthetic membrane protein, assembled onto tailored biotic–abiotic interfaces. This work communicates our research findings on the role of PSI microenvironment alterations at organic/inorganic interfaces, via biomimetic lipid membrane confinements and plasmonic coupling with Ag nano-pyramid structures, in tuning the photoactivated charge separation and photocurrent generations from surface-assembled PSI. The observed photocurrent enhancements and the associated mechanistic insights from this study will facilitate the future design of tailored interfaces that can optimally tune the photoactivity and photostability of PSI in solid-state bioelectronics.
