Maximum power point tracking based on differential conductance

Maximum power point (MPP) tracking technique based an optimized adaptive differential conductance technique was developed in this paper. The performance of the algorithm developed in this paper was evaluated at solar irradiance of 1,000, 800 and 600 W/m2 and at temperature of 298, 328 and 358 K. From the simulation results, it was observed that the impedance of the panel decreases as the irradiance increases while the impedance of the load is not affected by the irradiance. This technique was...

Improving the Efficiency and Stability of in air Fabricated Perovskite Solar Cells Using the Mixed Antisolvent of Methyl Acetate and Chloroform

Antisolvents play a significant role in obtaining high-quality perovskite films during the fabrication process. This paper reports a novel mixture of two antisolvents (methyl acetate and chloroform) that proves effective for fabricating high-quality perovskite films in a high humidity ambient. The results show that the use of methyl acetate alone as the antisolvent enables the fabrication of dense perovskite films (MAPbI3) in a high humidity ambient, but with a rough surface, while mixing...

Effect of Input Current and the Receiver-Transmitter Distance on the Voltage Detected by Infrared Receiver

This paper investigates the effect of the input current and the distance of separation between the IR transmitter and IR receiver on the voltage detected by infrared (IR) receiver Line-of-Sight IR propagation. The research was carried out using IR533C IR transmitter and FDS 100 IR receiver. Regulated digital power supply was used to provide stable 5V supply to the transmitter circuit. A 5V, 100kHz square wave from the signal generator was used to switch the BC338 transistor to modulate the...

Educational Administrative Strategies and Its Effect on Employers Job Performance A Review

This review paper comprehensively reviewed the administrative strategies adopted by some administrators for effective employer’s job performance. Different strategies were reviewed but the four major ones that were detailly reviewed in this paper are teachers’ involvement in decisions-making, proper delegation of duties and staff's warfare, open communications and adequate provision of instructional facilities to the employers and finally engaging employers regularly in workshop. Among al...

Development of Aduino based Software for Water Pumping Irrigation

This research paper undertakes the development of water pumping system that was capable of automatically managing water budgets from a reservoir through a microcontroller (Arduino Uno Microcontroller) subsystem. A user-friendly and efficient water management system that has the capability to irrigate farms based on automated algorithm, logic and electronic circuitry was developed. The Object Oriented System Analysis and Design (OOSAD) methodology was used for the analysis and development of t...

Development of Stable and Optimized Bandgap Halide-Chalcogenide Perovskite Materials for Photovoltaic Applications

The toxicity and instability of some metal-halides has made it unfovarouble to be used for the development and fabrications of perovskites despite its good Power Conversion Efficiencies (PCE). The need to suggest good perovskites absorber materials that has excellent Dimensionality, optical band gap, and power conversion efficiencies to substitute lead in photovoltaic application is very essential in the recent research. This research work reviewed and suggested the combinable good perovskite...

Development of Improved MPPT Algorithm Based on Balancing PSO for Renewable Energy Generation

Maximum Power Point Tracking (MPPT) is the method of operating the photovoltaic system in a manner that allows the modules to effectively transfer all the power generated from the panel to the load.Maximum Power Point (MPP) tracking technique based on Balancing Particle Swarm Optimization (BPSO) were successfully developed in this paper to solve the problem of premature convergence and also latency in convergence/tracking. The performance of the developedBPSO was evaluated at solar irradiance...

DESIGN AND IMPLEMENTATION OF FIRE PREVENTION AND CONTROL SYSTEM USING ATMEGA328P MICROCONTROLLER

The design and implementation of a fire prevention and control system using ATmega328P was successfully designed and implemented to curb the frequent fire outbreak in Africa. The system was designed to trigger alarm ON whenever gas leakage or smoke is detected and as well triggers ON fire extinguishing fan ON to suck the gas away from the premise. The Liquid Crystal Display (LCD) as well indicates the system performance measure of the premises at any point in time. The Arduino UNO is used as ...

Design and Implementation of an Industrial Heat Detector and Cooling System Using Raspberry Pi

Design and Implementation of an Improved Automatic DC Motor Speed Control Systems Using Microcontroller

Energy wastage is one of the major challenges that is facing the world now as there is insufficient supply of energy and the little ones supplied was not appropriately used. This energy wastage has made many researchers to engage more on the research to stop this energy waste as a result of inappropriate allocation of energy to some devices even when they don’t need it. This research work was able to design and implement an improved automated DC Motor speed controller system using microcont...

Design and Implementation of a Smart Surveillance Security System

Home security is essential for occupant’s conveniences and protection. This research project designed and implemented a comparatively inexpensive smart surveillance security system that automatically captures an intruder’s image through a raspberry pi camera module and PIR sensor and sends mail to the user via Wi-Fi using the users registered email address. This system operates by triggering the Pi Camera through Raspberry Pi whenever an intruder comes in range using PIR sensor. The Pi ca...

Comprehensive Review of Recent Electric Vehicle Charging Stations

The uncertainty associated with modelling and performance of Electric Vehicle (EV) design could be easily and efficiently reduced by using hybridized renewable energy sources. During the past decade the struggle for effective utilization of EVs was very high due to its unreliability interns of durability and sources of charge. This review classified charge station into renewable, nonrenewable and hybrid based on its sources of power generation. In addition, for this decade there is no extensi...

CAUSES AND PREVENTIVE MEASURES OF FIRE OUTBREAK IN AFRICA REVIEW

Fire is a visible effect of the process of combustion as a special type of chemical reaction which occurs when oxygen in the atmosphere reacts with some sort of fuel to bring out flame. This review research extensively detailed the causes, preventive and protective measure to be taken to curb fire outbreak in the society. This showed that the best way to avoid fire outbreak is by adopting preventive and protective measure which includes avoidance of using phone in the kitchen, fueling generat...
