Current Trends in Development of Photosynthetic Bioelectrochemical Systems for Light Energy Conversion

During the past few decades, intensive research has been focused on the application of biological photosynthetic processes for “green” electrical power generation. In this contribution, we consider different possible photobiocatalysts, such as isolated photosystems, thylakoid membranes (TMs), and whole photosynthetic organisms suitable for building bioelectrochemical systems for light energy conversion. We discuss numerous approaches to immobilization and wiring of the photobioagents on conductive surfaces and various electrode materials and mediators employed in state-of-the-art photobioelectrochemical systems, and we highlight the latest achievements in photocurrent intensity and power output of the solar-driven biodevices.
