We can not imagine the civilization without energy specially electrical energy. In broader sense we can divide electric energy in two types, one is non- renewable energy and the other is renewable energy. Due to the drawbacks of non-renewable energy and advantages of renewable energy, the use of renewable energy is increasing day by day. Eventually new sources and technology is coming out. One of the new technologies of renewable source is the production of electricity from Pathor Kuchi Leaf (PKL), the scientific name of that is Bryophyllum Pinnatum. We can easily produce electricity from PKL by immersing a Zinc and a Copper plate in to the juice of PKL. This system produces theoretically 1.1 volts per cell. So if we need higher voltage or higher current we need to combine more cells to get the desire power. To keep it in mind, In this paper a new approaches is presented to get more power from per cell of the PKL system which is out of traditional cell concept for per cell power. Keywords: New approach, PKL electricity, Utilization, Soil Pot, Per pair per volt. I. Introduction A cell is an arrangement of two electrodes in an electrolytic solution capable of producing electricity. In a cell electricity is produced due to the chemical reaction within the cell between electrodes and electrolyte [1-9]. How much voltage will be produce in a cell depends mainly on the electrodes and electrolyte used. So for a particular set of electrodes this voltage is defined in the Table of Standard Reduction Potentials. As per the table half reaction potential for copper is 0.34 Volts and the half reaction for zinc is -0.76 Volts[10-19]. So if we consider a cell with Cu and Zn electrode than the cell potential will be 0.34–(- 0.76) =1.1 Volt[20-29]. So if we need to produce 6 volts we need to connect six cells in series. Again if one cell can generate 0.5 ampere current and we need 2.0 ampere current then four Cells will be connected in Parallel[30-39]. So for a power of 12 watt with 6 volts from this type of cell we need to connect six cells in series to get 6 volts and to get 12 watt power we need 2 ampere current to flow through the circuit. Hence, it will be needed to connect 4 sets of 6 cells in parallel combination. For higher power we need to undergo same series parallel combination of cells, which makes the system more complex and lower the efficiency of the system[40-47]. II. Theory II.A Effect of combination of PKL cells The power produced by PKL cell is low. Moreover it has a high internal resistance. Due to this high internal resistance the voltage drop as well as power loss within the cell is high[48-57]. On the other hand we need to undergo series connection of several cells to get the desire voltage level from the system. When we connect several cells in series it also adds the internal resistances of individual cells[58-65].So the internal resistances of the combination of cells multiples and become higher. This high value of internal resistance is a very big barrier to get high power. For an example, let us consider a PKL cell with a cell voltage is 1.0 volt with a internal resistance 0.6 Ω[66-75]. To use this PKL power for a 6 volt system we need to connect 6 PKL cells in series. Also let us consider the load needs 0.5 Ampere current[76-85]. Figure 1 shows the connection for 6 PKL cells in series.
