“…Due to the hydrophobic character of the protein and to the presence of detergent molecules, necessary to achieve its solubilization in water, the most part of the electrochemical study has been carried out in the presence of substances soluble in solution, which are able either to mediate the electron transfer to an electrode or to undergo selective electron transfer with one of the components of the chain [60,61].…”

“…The photocurrent generated during amperometric studies was 45 μA/cm 2 , significantly higher than other reported PSII results. 61,62 The Willner research group reported the first PSII bio-solar cell. The bioanode consisted of a Au electrode with a layer of electropolymerized poly(mercapto-p-benzoquinone) over which PSII isolated from Mastigocladus laminosus was adsorbed.…”

Photobioelectrochemical cells are devices which have been developed over the past few decades and use photosynthetic catalysts for solar energy conversion or biofuel production. In this paper, a critical review of reported photobioelectrochemical systems is presented. The systems discussed include several types of photobioelectrocatalysts: whole cells, organelles, and enzymes. Special attention is paid to power or product generation as well as immobilization and electron transfer strategies used. The issues that need to be addressed in order for such systems to compete with current technologies are also discussed.

A microelectromechanical systems (MEMS) photosynthetic electrochemical cell ( PEC) was demonstrated that harnesses the subcellular thylakoid photosystems isolated from spinach cells to convert light energy into electricity. Subject to light intensity of 2000 mol photons/m 2 /s, it generated an open circuit voltage (OCV) of 470 mV and a current density of 1.1 A cm 2 at 5.2 V. In the dark, the PEC continued to yield power for a few minutes using reduced equivalents generated during illumination, generating 330 mV OCV and 0.1 A cm 2 with a 1 k load. The output level is comparable to other MEMS biological fuel cells previously reported. The biosolar cell was bulk-micromachined from silicon and Pyrex substrates and assembled like a fuel cell in an anode-PEM-cathode configuration. This biosolar cell could have potential to serve as a power source for micro-scale devices like remote sensors.[1359]
