“…On this basis, we justify the utility of the graphite over the SCE, and also suggest its use in PG in future research. Further, the light‐harvesting ZnO, SnO 2 and ZnO‐SnO 2 nanostructures anchored with the dye sensitizer, 61 cetryl hexadecyl ammonium bromide as charge transfer carrier, 62 a new vertical illumination configuration with light coming between the two electrodes, 63 2D‐semiconductor nanosheets photocatalyst, 64 2D‐graphene‐based photo‐sensitizer material, 65 counter electrodes (involving inorganic materials, composites, Platinum, multiple compounds, carbon materials, and polymers), 66 most efficient dye electron acceptor‐reductant electron donor combination redox couple, 67 and boron nitride‐based materials 68 may also be exploited in graphite counter electrode modified PG cells for further advancement in the photogalvanics.…”

An optimization, photo‐stability, and hysteresis property of the Graphite counter electrode‐modified Tropaeolin‐O (TPO) photo‐sensitized photogalvanic (PG) cells has been investigated. A complex H‐shaped cell design, a costly and delicate saturated calomel electrode (counter electrode), and a heavy sensitizer molecule (dye having high molecular weight, low diffusivity, and low photo‐stability) have been exploited for fabricating most of the PG cells so far. All these factors are not suitable for the fabrication of durable and cheap PG cells. Therefore, in the present study, the highly conductive/catalytically active robust graphite electrode with TPO dye photosensitizer (having a low molecular weight, higher diffusivity, and higher photo‐stability) has been exploited with diffusion‐friendly low cost and a simple transparent cylindrical glass tube. The cheap and robust graphite counter electrode has been exploited for optimization and long‐term study of the TPO photo‐sensitized PG cells. The observed electrical output is potential 676 mV, current 2000 µA, and power 340.0 μW. The power, current, and efficiency, have been found quite independent of the illumination window size. The potential and current have been observed to be quite stable over a long time during illumination, and the same has been supported by the hysteresis study.

“…On the basis of the published literature, [6][7][8]16,17,26,[31][32][33][34][35] the most plausible mechanistic aspect of the photoinduced generation of the so-called photo-current using tropaeline-O dye sensitizer (TPO)-oxalic acid reductant-Pt-SCE photogalvanic system is proposed as below.…”

“…The effect of the different illumination window sizes on the cell has been studied by constructing in all four photogalvanic cells (i.e., cell no. [32][33][34][35] while maintaining all conditions in common for all cells, except the size of the illumination window (Supporting Information: Table S14). The power, current, and efficiency have been obtained quite similar at all illumination window sizes studied (Supporting Information: Table S15).…”

Higher molecular weight coupled with the higher D L of H-shaped cell lowers the electrical output of the cell, and this may be the most plausible reason behind the relatively lower electrical output of these already reported studies.…”

The photogalvanic (PG) cells involve a change in the electrode potential by photochemical processes along with the diffusion of ionic species through the bulk electrolyte. The PG cells have used so far the complex H‐shaped cell design, heavy sensitizer molecules with low diffusivity, and low photo‐stability. All these factors are not conducive to the fabrication of cheap cells with good electrical output. To address all these concerns, the tropaeline‐O dye photosensitizer (a low molecular weight molecule with higher diffusion and higher photo‐stability) has been exploited with diffusion‐friendly low cost and a simple transparent cylindrical glass tube. The optimum values of the cell's electrical parameters are: potential 998 mV, current 3200 µA, and power 829.5 µW, and it is quite similar at all illumination window sizes.

Summary The technology to harness solar power has been evolving continuously with a recent focus on simultaneous power storage as well. Photogalvanic (PG) cell is a promising technology for simultaneous solar power and storage. The nature of the sensitizer, reductant, surfactant, and electrodes are the key factor determining the efficiency, stability, and power storage capacity of the PG cells. The use of a more stable dye with good diffusivity and conductivity realized through the most suitable surfactant has evaded the attention of researchers. Therefore, in the present study, the photogalvanics of the stable Quinoline Yellow (QY) dye photosensitizer in the presence of the Dodecyltrimethyl Ammonium Bromide (DTAB) surfactant, and Cellobiose reductant at an elevated pH has been studied for solar energy conversion and storage. The entirely novel and new photogalvanic system has shown abruptly enhanced electrical performance of the PG cell as potential 900 mV, current 10 000 μA, and power 989 μW. Encouraging photogalvanics may be attributed primarily to the greater QY dye‐DTAB surfactant interaction enhanced dye solubility, stability, and diffusion through the electrolyte. Spectrometric and conductometric study of the electrolyte has validated good photostability and conductivity of the electrolyte solution. Based on published literature and observed facts, a most plausible mechanism for the photogeneration of the current and power storage capacity has also been proposed. The present research does not introduce any new mechanism for the photo‐generation of the current, but a new and novel cell fabrication design with greatly enhanced electrical output in comparison to that in earlier studies. Novelty statement The cationic Dodecyltrimethyl Ammonium Bromide surfactant and Quinoline Yellow (QY) anionic dye sensitizer has been exploited in the presence of Cellobiose reductant for enhanced dipole‐dipole interactions for further enhancing the photogalvanics. The hypsochromic and hypochromic shift of main band of QY in electrolyte may be attributed to the QY‐DTAB complex formation due to interaction between the anionic QY dye and cationic DTAB surfactant. The present study shows abruptly enhanced electrical output (potential 900 mV, current 10 000 μA, power 989 μW).
