Abstract

This review discusses methods for increasing the efficiency of photoelectric conversion systems using photosystem I (PSI) and photosystem II (PSII) isolated from thermophilic cyanobacteria. The structure and electron transfer pathways for PSI and PSII are described, followed by a description of a new type of photoelectric conversion system and its application in light-sensing devices using PSI or PSII. Photoelectron transfer is demonstrated by spectroscopic and electrochemical measurements. A strategy to enhance photocurrent intensity is described, involving wiring photosynthetic reaction centers onto a self-assembled monolayer on an electrode. We review the fundamental concept behind these semiartificial photosynthetic systems, as well as representative examples from published papers, including those from our laboratory.
