At present, there is a dire need of electricity around the world. There are a lot of remote areas where grid electricity is absent. So that some innovations are needed there for electricity production. The nonrenewable energy sources are limited. But we have a plenty of renewable energy sources. Although renewable energy sources are more safer for use in human life and the environmental pollutions. After finishing the renewable energy sources, people can use sun and plants for electricity generation. In our research paper, an idea has been taken for electricity production from pandan leaves because plants and leaves grow everywhere. The current and voltage have been generated from the pandan leaves which have been further used to light the LED lamp. Lighting the LED bulb proved that the idea was successful for electricity generation from pandan leaf. It is not limited to LED bulb; further, this idea will be used for other electric appliances. Pandan leaf (PL) has been used for getting electricity. The scientific name of the pandan leaf is Pandanus amaryllifolius. The pandan leaf extract has been used for electricity production. A comparative study has been done for both with and without secondary salt. CuSO4 has been used as a secondary salt. It has been studied the several parameters like open circuit voltage, load voltage, short circuit current, load current, maximum power, load power, and internal resistance. These parameters have been developed for both with and without secondary salt. It is shown that the performance for with secondary salt is better than the without secondary salt. The internal resistance was less for using the secondary salt. After doing this research work, it can be concluded that result is positive for electricity generation from pandan leaf.
Extract of Green Chili—A New Source of Electricity
(Springer Science and Business Media Deutschland GmbH, 2021) Ohiduzzaman, M.,; Khan, K.A.,; Islam, S.,; Hossain, M.S.,; Rasel, S.R.
Green chili is abundantly available for everywhere in the world. It is cultivating for cooking in curry. It can be used a green source of energy. Previously, it has been generated electricity from different vegetative and fruits. Electrochemistry is the responsible of mechanism for electricity generation from vegetative and fruits. In this paper, it has been used as a source of electricity using electrochemical cell. The Zn/Cu-based electrodes were used, and the extract of the green chili was used as an electrolyte. The green-electrochemical systems achieve the reduction reaction with a certain voltage for which electrons transfer between the cathode and anode. Here, cathode means gain of electron, and anode means loss of electrons. In this research paper, zinc is used as an anode, and copper is used as a cathode. The electrons react with Cu2+ and H+. The Cu2+ and H+ eventually convert into Cu and H2 atoms. Finally, it is shown that Cu atoms were deposited onto the copper plate, and H2 releases from the green chili electrochemical cell. The experimental results were observed with and without adding copper sulfate solution $${\text{CuSO}}:{4} \cdot 5{\text{H}}_{2} {\text{O}} $$ as a secondary salt. The outcome of the research work improvises a better understanding on the electricity generation technology of the system.
Studies on Synthesis, Characterization, and Monitoring of Ag NPs for Power Production Using Tomato
(Springer Science and Business Media Deutschland GmbH, 2023-06-27) Islam, F.; Khan, K.A.; Hossain, M.S.; Rasel, S.R.; Akter, S.
In this research paper, tomato extract has been synthesized and characterized for Ag NPs. This synthesized Ag NPs have been used for power production. This produced Ag NPs using tomato extract are very useful and eco-friendly. Different characterizations have been conducted UV-visible spectroscopy, FTIR, XRD, and FESEM. It is found that the absorption peak at around 428 nm for UV-visible spectrum. It is also found that the biomolecule compounds were responsible for the reduction and capping material of silver nanoparticles using FTIR spectra. It is also found that the particles to be crystalline in nature by XRD study, with a face-centered cubic (FCC) structure. The power production activity of Ag NPs was assessed to find their potential use in electrochemical cell. It is found that the open circuit voltage (Voc), short circuit current (Isc), and maximum power (Pmax) were better for using Ag NPs from the tomato extract of a single electrochemical cell.

Synthesis, Characterizations of Silver Nanoparticles (AgNPs) and Monitoring for Power Production Using Drumstick Leaves
(Springer Science and Business Media Deutschland GmbH, 2023-06-23) Khan, K.A.; Haider, M.T.; Hossain, M.S.; Rasel, S.R.
The drumstick fresh leaves in aqueous extract form have been used (Moringa oleifera) for green synthesis of silver nanoparticles (AgNPs). The green synthesis method has been conducted for the production of AgNPs for the application in power production. The different methods are developing for synthesis of AgNPs for multiple applications. It is found that green synthesis from Moringa oleifera leaves is cost-effective and echo-friendly. The synthesized AgNPs have been characterized through ultraviolet–visible spectroscopy (UV–Vis), Fourier transform infrared (FTIR), powder X-ray diffraction (XRD), field emission scanning electron microscope (FESEM). It is found that the UV–visible spectrum contains AgNPs in the aqueous medium, and it is also found that absorption peak was at around 332 nm. It is again found from the FTIR analysis that the bimolecular compounds were responsible for the reduction and capping material of AgNPs. It is also found that from the XRD study that the particles to be crystalline in nature, with a face-centered cubic (fcc) structure. The power production activity of AgNPs was assessed to find their potential use in an electrochemical cell. Most of the results have been tabulated and graphically discussed.
