In DSSC, sensitizer imitates photosynthesis process in plants by absorbing the photon energy from the sunlight. This research investigated methanolic extracted chlorophyll dye sensitizer in comparison to water extracted and bare chlorophyll. Density Functional Theory (DFT) and Time-Dependent Density Functional Theory (TD-DFT) methods in Gaussian 03/Gaussview 03 software were used to investigate its optical and electronic properties. Each of the molecular structure (methanol and water) was individually attached to chlorophyll, and their performances were determined. Results demonstrated that the absorbance spectrum of chlorophyll shows a broad peak in the visible range from 400 to 700 nm with its highest peak at 430 nm. Energy gap of chll-m between the E(LUMO) and the conduction band of TiO2 semiconductor, EC(TiO2) or so called as VOC is slightly smaller compared to water (chll-w). Meanwhile, the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) bandgap of chll-m is slightly higher at 2.13 eV. Finally, position of LUMO to redox electrolyte in chll-m is the lowest, which is favourable for faster electron transition. From observation, chll-m demonstrated better optical and electronic properties compared to its counterparts and hence good for chlorophyll sensitizer extraction.","PeriodicalId":313365,"journal":{"name":"Journal of Electrical & Electronic Systems Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131649722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, an off-grid SHS has a solar panel, a lead-acid battery, a Pulse Width Modulation (PWM) solar charge controller, and 12V DC power operated electrical home appliances; in some cases, a DC to DC converter or a DC to AC inverter has been connected. So far, various SHS packages have been introduced, each with a set of product features and prices. Since the majority of SHS are small in size, producing energy is inadequate to satisfy the customer's demand. This study introduces a new feature that incorporates both analog PWM solar charging techniques and a DC to DC (12V to 120V) converter to satisfy the needs of existing off-grid SHS users. The design of solar charging includes improved charging techniques i.e surge voltage and lightning protection. The result produced is a noisefree switching gate drive signal and high-performance fixedfrequency current mode controllers. The new controller's design also reduces the number of devices in the SHS; thus reduces the controller's total production cost.","PeriodicalId":313365,"journal":{"name":"Journal of Electrical & Electronic Systems Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116359646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With an input power of 240 mW (EDFA) and 2000 mW (FRA), a 96% power conversion efficiency is obtained and produced a stable multiwavelength for L-band source with peak power of -10 dBm for ring laser, -25 dBm for single pass linear and -5 dBm for bidirectional linear laser. The lasing threshold obtained at 50% arm coupling ratio for ring laser is also slightly lower than other value reported previously. The interesting features of the proposed laser systems is the low threshold power, high output power, high number of lasing line and high pump conversion efficiency.","PeriodicalId":313365,"journal":{"name":"Journal of Electrical & Electronic Systems Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114792778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents the development of a vehicle to minimize the spread of the disease. The Coronavirus-Autonomous Ground Vehicle (COR-AGV) uses Ultraviolet Light (UV) rather than liquid sanitiser. The use of UV light as a disinfectant is proven in the medical field, where many medical appliances were disinfected using UV light without the need for alcohol substances. Previous research showed thatsimilarCoronavirus such as SARS and MERS lost their ability to infect when exposed to the UV for a particular durationasthe exposure causeddamageto the virus's DNA sequence. The COR-AGV presented herewith uses UV Light to carry out the disinfection task autonomously. The COR-AGV, equipped with a far-UVC light array, navigates autonomously within the targeted areas to sweep systematically, scan and disinfect. The COR-AGV is equipped with camera and sonar sensors to enable path planning and obstacle avoidance in confined spaces and outdoor environments. A GPS is included to assist the COR-AGV navigation system. Simulation test runs were performed to check the adequacy of the rover in performing disinfection. The COR-AGV perform disinfection on the wall surface with more than 50% of the wall surface were covered for disinfection in various floor layouts, while being able to perform obstacle avoidance within the test area. Thus, COR-AGV can be adapted prior to the actual pandemic event to enhance its level of performance. The performance of COR-AGV can be improved with additional sensors such as Computer Vision or LiDAR sensor.","PeriodicalId":313365,"journal":{"name":"Journal of Electrical & Electronic Systems Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122928336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
