Current levels by anode type and device configuration. a Synechocystis peak photocurrents in device mode (at ‘short-circuit’) and half-cell operation (with reference electrode), during a photon flux of 460 µmol m−2 s−1. b As (a), number of collected charges during 90 minutes of illumination at photon flux of 512 µmol m−2 s−1. c Current generated by Shewanella cells for each anode type. d, e Schematic illustrating the device and half-cell operation, respectively. The potentiostat connections for reference (RE), working (WE) and counter electrode (CE) are indicated
