“…Though the in‐device interfacial electronic structures are not explored in the field of biophotovoltaics, in the recent few years there are a number of reports adopting design principles based on “band gap approach.” Stepping beyond the conventional bio‐electrochemical cells, in these reports, attempts are made either to construct solid‐state multilayered devices with exciton/charge transfer modes decided purely based on band‐structure approach or to introduce certain new design principles based on the band‐gap approach in a biohybrid device retaining a basic electrochemical cell design. The first category of devices is solid‐state photovoltaic cells integrated with photosynthetic proteins which include design principles adopted both from the natural photosynthesis and from the conventional photovoltaics.…”

“…This has been proven possible by orienting the proteins in a desirable way on to the electrode. In an earlier attempt, even without special immobilization techniques, the PS1 proteins (though not 100% of them) were found to have the tendency to orient themselves with P700 site facing up and F B site adhering to the ITO in a BHJ device of structure ITO/PS1/MEH‐PPV:PCBM/(LiF or MoO 3 )/Al, where the BHJ is formed by the blend of the conjugated polymer MEH‐PPV (poly[2‐methoxy‐5‐(2′‐ethylhexyloxy)‐p‐phenylene vinylene]) and the fullerene derivative PCBM ([6,6]‐phenyl‐C 61 ‐butyric acid methyl ester) (Figure c,d). Based on the type of interlayer (Electron‐extracting LiF or Hole‐extracting MoO 3 ) coated on the BHJ, conventional‐ and inverted‐OPV structures were constructed with differences only in the direction of charge transport.…”

Emulation of natural photosynthesis is central to modern photovoltaic research targeting sustainable and economic ways of solar energy harvesting. Natural photosynthetic systems have succeeded in efficiently harvesting solar energy which is key to the sustenance of life on earth. With numerous advances in understanding the structure and function of the natural photosystems, the last decade has witnessed new perspectives in developing bioinspired photovoltaics. Interestingly, organic photovoltaics (OPVs) adopting photosynthetic design principles and biophotovoltaics (BPVs) adopting solidstate device architectures have now converged at a juncture. Several reports in recent years point to a new scope of improvement in OPVs and BPVs stemming from mutual inspiration. At this juncture, there are new perspectives by which a BPV can be designed that were previously limited only to conventional optoelectronics. Treating natural pigment-proteins as optically and electronically functional materials in any photovoltaic design, from the band-theory viewpoint, is a promising direction for advancing BPVs beyond the boundaries of bioelectrochemistry. This article presents an overview of selected reports on BPVs in the last few years utilizing new design concepts based on band-theory and its associated principles. In light of this, the scope of the band-structure approach in BPVs is discussed, eliciting prospective research directions.

Ever-evolving, modern computing hardware, from processors to memory storage, relies on electronic components of extremely small size and high energy efficiency. [1] Molecular tunneling junctions, in which the charge transport properties of molecules are exploited in devices, have considerable potential in this context because subtle changes at the atomic scale can translate into unique and useful effects at the device level. [2,3] By exploiting the chemical nature of molecular electronics, these effects are exemplified in photoisomerization, [4-8] , protonation, [9,10] electrostatic gating, [11,12] reduction-oxidation, [13] etc., giving rise to molecular resistors and molecular diodes in both

Charge separation and transport through the reaction center of photosystem I (PSI) is an essential part of the photosynthetic electron transport chain. A strategy is developed to immobilize and orient PSI complexes on gold electrodes allowing to probe the complex's electron acceptor side, the chlorophyll special pair P700. Electrochemical scanning tunneling microscopy (ECSTM) imaging and current–distance spectroscopy of single protein complex shows lateral size in agreement with its known dimensions, and a PSI apparent height that depends on the probe potential revealing a gating effect in protein conductance. In current–distance spectroscopy, it is observed that the distance‐decay constant of the current between PSI and the ECSTM probe depends on the sample and probe electrode potentials. The longest charge exchange distance (lowest distance‐decay constant β) is observed at sample potential 0 mV/SSC (SSC: reference electrode silver/silver chloride) and probe potential 400 mV/SSC. These potentials correspond to hole injection into an electronic state that is available in the absence of illumination. It is proposed that a pair of tryptophan residues located at the interface between P700 and the solution and known to support the hydrophobic recognition of the PSI redox partner plastocyanin, may have an additional role as hole exchange mediator in charge transport through PSI.
