“…Photosynthesis is a green and highly efficient energy conversion technology that converts solar energy into chemical energy . In nature, there are two different photosynthetic systems: chloroplast system in plants as well as algae and bacteriorhodopsin (bR) system in Halobacterium salinarum . As a light‐driven proton pump, bR captures light and transports protons from intramembrane to extramembrane directionally, and subsequently converts proton gradient to chemical energy .…”

As a light‐driven proton pump, bacteriorhodopsin (bR) captures light and transports protons directionally. Here, a new bR‐based bioelectronic device that employs the chemiluminescence from luminol as an endogenous light source to generate steady current is designed. Purple membrane embedded with bR is modified on indium tin oxide (ITO) electrode followed by electrostatically binding of cationic oligo (p‐phenylene vinylene) derivative (OPV). The device is fabricated by coupling bR/OPV electrode and bare ITO electrode. As a suitable luminescence acceptor of luminol, OPV emits green light through chemiluminescence resonance energy transfer (CRET), which is capable of exciting ground state bR (bR570) nearby to initiate photocycle. Simultaneously, luminol emits blue chemiluminescent light which can be absorbed by M410 intermediate in photocycle, accelerating its reconversion to bR570 by shortcuts. As a result, the photocycle is accelerated and stabilized to generate a stable photocurrent. Furthermore, this study achieves to use oxygen and glucose as the initial source of hydrogen peroxide and produce stable photocurrent by taking advantage of the cascade reaction of glucose oxidase and horseradish peroxide. This provides a proof‐of‐concept for successfully using the CRET system as endogenous light source and provides new ideas for energy utilization and conversion taking advantage of natural bR‐based photosynthetic systems.

“…Introducing inorganic materials to bR as such for enhancing the photoelectric properties of hybrid structures is not rare. Except TiO 2 , Zhibin Guo et al firstly illustrated a novel photovoltaic stacking system with the structure of bR/AuNPs heterogeneous multilayers with improved photoelectric performance, as shown in Figure 15 [ 29 ]. With this stacking system, photoelectric performance was improved effectively owing to the cooperative control of proper diameter of AuNPs and the stacking layers.…”

“…Then, bR was applied in the field of computer systems and sensors, leading to production of optical volumetric memories [ 20 , 21 , 22 ], holographic associative processors [ 23 , 24 ] and motion biosensors [ 25 , 26 , 27 ] in the early 2000s. After that, bR was used to compound with a variety of photoelectric materials, which resulted in the generation of photovoltaic cells based on different composite material systems [ 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. In 2011, the spectral range of bR related detectors was broadened.…”

Bacteriorhodopsin protein extracted from Halobacterium salinarum is widely used in many biohybrid electronic devices and forms a research subject known as bioelectronics, which merges biology with electronic technique. The specific molecule structure and components of bR lead to its unique photocycle characteristic, which consists of several intermediates (bR, K, L, M, N, and O) and results in proton pump function. In this review, working principles and properties of bacteriorhodopsin are briefly introduced, as well as bR layer preparation method. After that, different bR-based devices divided into photochemical and photoelectric applications are shown. Finally, outlook and conclusions are drawn to inspire new design of high-performance bR-based biohybrid electronic devices.

“…In addition to PS1 and PS2, LHC2 which is a light harvesting complex extracted from oxygenic phototrophs has also been used in biophotovoltaic devices in recent times. Other than this, there are also reports on biophotovoltaics using other light harvesting pigment–protein complexes like phycocyanin (PC) and proton‐pump based photosynthetic proteins like bacteriorhodopsin (bR) …”

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.
