Design, Construction, and Testing of Maximum Power Point Tracking (MPPT) charge controller for Photovoltaic (PV) power generation

Maximum Power Point Tracking (MPPT) charge controller is designed for using an easy and effective way to charge a 12v battery and a laptop charger of 19v simultaneously through the principle of the bulk-boost converter. This research work is suitable for 150W solar panels, as the Maximum Power Point (MPP) of Photovoltaic (PV) power generation systems changes with variation in atmospheric conduction, an important consideration in the research work is efficient of PV systems is to track the MPP correctly. It enhances battery life by providing higher efficiency to it. The efficiency of the research work was calculated from the power dissipated and also calculate the point at which the battery extracts maximum power from the PV module. As the work was tested the voltage and current were obtained which was used to plot the voltage-current and voltage-power characteristics curve. A lot of works have been published on this topic, but none has researched MPPT that will charge both 12v battery and 19v laptop charger  imultaneously. Also, only a few of them show the theoretical and experimental relationship between MPPT and PWM charge controller the output power was calculated theoretically to be 112W while, experimentally we obtained it as 111W.

SIMULATION ANALYSIS OF OPTICAL PROPERTIES OF INDIUM TIN OXIDE (ITO)

TCO (transparent conduction oxides) have been suitable materials for optoelectronics applications, Indium Tin Oxide is an n-type transparent conducting oxide semi-conductor, which possess a combine properties of transparency to visible light and electrical conductivity, its features have been studied in this dissertations using MATLAB computer programming. The features which consist optical and electrical properties were simulated using MATLAB programming, the drive ITO models were used within the range and limit of other researchers, whose have done the researches experimentally. The models were used to simulate optical transmittance, optical absorptions, and....
