“…The highest efficiency was obtained when the dry turmeric soaked into methanol at pH 3.5 is 0.287%. [ 47 ] A dye was extracted from Aloe Vera gel using several solvents such as purified water, ethanol, acetone, isopropanol, and DMSO. The dye‐containing DMSO provides the highest η than the rest of the solvents, which may be due to the enhancement of absorbance.…”

“…This is due to the wide range of absorption spectra and enough electrons regeneration that occurs by mixing dyes. [ 47,56,75 ] The addition of metal complexes in natural dye may be improved the η value, i.e., Fe in quercetin to make a complex dye increased the η , which value is double than natural quercetin. [ 76,77 ] It is clear that from various aforementioned researches used methodologies and materials are cost‐effective, nontoxic, and environmentally friendly for improving η in DSSCs where the cosensitizers played an important role.…”

Dye‐sensitized solar cells (DSSCs) have turned a new horizon in energy research due to their widespread exploration over two decades by improving efficiency, cost‐effectiveness, and easy process than inorganic‐based solar cells. The major challenges are metal complexes on designing the cells and sustainability implications for further rapid expansion due to its toxicity. To overcome the problems associated with metal complexes, the dyes are extracted from bionatural sources such as flowers, fruits, barks, petals, roots, leaves, and beans of plants. These organic dyes are being nontoxic, cost‐effective, abundant, environmentally friendly, and easy to extract, which is made them extensively applicable for DSSC. Through this review, readers may get an idea about the effect in the efficiency of the solar cell by applying variable semiconductors, effects of solvents, variable light‐harvesting pigments, types of electrolytes, and modification of counter electrodes by certain polymeric materials or nanomaterials. Furthermore, the effects of methodology, processing temperature, and pH of the medium during synthesis on solar cell parameters, such as the efficiency of DSSC, are critically analyzed which are reported by other researchers.

“…The cultivation of PKL is so much easy [126,127]. This plants grow whether its leaf is kept on the ground and hence can be cultivated in a vested land, roof top of the house, courtyard and tubs what so ever [115][116][117][118][119][120][121][122][123].…”

“…If we can generate electricity from living plants or trees, everyone wants to be planting the trees in ones surroundings for getting electricity. Governments of many countries also suggested and motivated such a process of plantation of trees and plants to get electricity [61][62][63][64][65][66][67][68][69][70][71][72][73][74][75]. As a result, the number of plants and trees in the globe will also increase, which indirectly will save our planet from the serious issue of global warming by the process of plantation in near future.…”

Electricity from PKL tree has been developed using PKL extract previously. In this work, electricity production has been developed using living PKL tree. It has been studied that an electrochemical cell has been developed using living PKL tree. The experimental data have been demonstrated in that way, hence this method is feasible and effective. Electricity has been conducted from PKL (Pathor Kuchi leaf) using PKL extract with positive and negative electrodes. Several research papers have been published on it in the recognized journal at home and abroad. This research work has expressed the electricity generation from living PKL tree. It can be found that due to the difference of the pH between the soil and the living PKL tree, electricity can be produced. The performance of this electricity has been studied. This work has been developed by authors, which produced electricity from living PKL tree without damaging the PKL plants. The unused suitable land areas such as hilly areas, forest areas, and coastal areas, those could supply clean power for remote communities all over the world.

The efficiency of any electric cell or battery is very important. To keep it in mind it has been studied the columbic efficiency, voltaic efficiency and energy efficiency of a PKL (Pathor Kuchi Leaf) Quasi Voltaic Cell or Modified Voltaic Cell. It was found that the columbic efficiency data illustrated that this efficiency was lower comparing to other efficiencies may be the absence of salt bridge or separator between the electrodes. Because, our designed and fabricated PKL cell does not have any salt bridge. So that the internal resistance is lower than the traditional voltaic cell and as a result more current was found. The voltage and current changes with time and I–V characteristics for PKL unit cell, module, panel and array have also been studied. It is shown that the voltaic and energy efficiency have been studied. However, the highest efficiency was obtained for 40% PKL sap with 5% secondary salt in 55% aqueous solution, which implies that the concentration of PKL juice can play an important role regarding efficiency. It was also found that the average energy efficiency was 97.43% and it was also found that the average voltaic efficiency was 57.29%. Finally, morphological study FESEM (Field Emission Scanning Electron Microscopy) has also been performed. It is seen that the results confirmed that Zn was deposited on the Cu surface during the electro deposition process in PKL solution. Using AAS, it has been measured the concentration of [Cu2+] as a reactant ion and the concentration of [Zn2+] as a product ion those have been tabulated and graphically discussed. The variation of pH has also been studied with time and which was also tabulated and graphically discussed.
