Review ArticleOpen accessIn the abstractArchitecture of an Ultra-Low-Power Fully Autonomous Universal Power Conditioner of Energy Harvester for Wireless Sensor Networks: A ReviewYeo Kim Heng, Md. Shabiul Islam, Susthitha Menon et al.A fully autonomous Universal Power Conditioner (UPC) that can accept energy from any micro-energy harvester (e.g., photovoltaic, thermoelectric, electromagnetic, piezoelectric etc.) is proposed. Generally, UPC removes the need of multiple optimized source specific converters. But, the proposed UPC architecture will be Ultra-Low-Power (ULP) with maximized efficiency to support the low energy levels generated by harvesting sources. This UPC uses a … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 28 Mar 2016 · 7,786 accessesView PDFCite
Research ArticleOpen accessIn the abstractFast and Robust Maximum Power Point Tracking for Solar Photovoltaic SystemsHuiying Zheng, Shuhui LiSolar Photovoltaic (PV) energy is becoming an increasingly important part of the world's renewable energy. In order to develop technology for efficient energy conversion from a solar PV system, this paper studies typical Maximum Power Point Tracking (MPPT) control techniques used in solar PV industry and then proposes a close-loop and adaptive MPPT method for reliable and rapid extraction of … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 17 Jan 2016 · 7,784 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Dynamic Simulation of a Combined System Integration Concentrating Photovoltaic/Thermal Solar Collectors and Organic Rankine CycleFrancesco Calise, Massimo Dentice d'Accadia, Maria Vicidomini et al.This study presents the design of a novel ultra-high efficient solar power system. The system is equipped with a concentrating PhotoVoltaic/Thermal (CPVT) solar collectors bottomed by an Organic Rankine Cycle (ORC). The basic idea is to use a high temperature CPVT device producing simultaneously electricity and hot diathermic oil. Then, this hot fluid is used to supply heat to the … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 17 Apr 2015 · 8,659 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalyze the Absorption Properties and I-V Characterization of Dye Sensitized Solar Cell Using Ruthenium DyeAnees Ur Rehman, Farooq Aslam, Haseeb Ahmad KhanIn this study, Dye Sensitized Solar Cells (DSSC) has been fabricated using natural organic dye extracted from Ruthenium Dye and its I-V characterization and absorption properties have been analyzed. It is observed that the selected natural dye absorbed all visible light and supports electrons motion across the semiconductor interface. The dye acts as sensitizer because the titanium dioxide (TiO2) cannot … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 4 · 30 Dec 2014 · 7,395 accessesView PDFCite
EditorialOpen accessIn the abstractON THE CHALLENGES OF THE USE AND INTEGRATION OF RENEWABLE ENERGY SOURCESMariano MartínOverview: Although renewable energy sources are plentiful, their availability is highly volatile in time and distributed across regions while and the processes that transform them into useful power or chemicals are underdeveloped. In this work we discuss on the scope for the use and integration of renewable energy sources and the future development of the alternatives. Energy, the sources and … …Energy Research Journal, Vol. 5, Issue 1 · 11 Sep 2014 · 7,543 accessesView PDFCite

Research ArticleOpen accessIn the abstractEvaluation of Single-Pass Photovoltaic-Thermal Air Collector with Rectangle Tunnel AbsorberGoh Li Jin, Adnan Ibrahim, Yee Kim Chean et al.Problem statement: Photovoltaic solar cell generate electric by receiving sun light or solar irradiance. But solar cell received heat from solar irradiance as well and this will reduced the efficiency of the solar cell. The heat trap at the solar photovoltaic panel become waste energy. Approach: The solution for this was by adding a cooling system to the photovoltaic panel. … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 8,332 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Development of a Photovoltaic Power System for Tropical Greenhouse CoolingFaisal Mohammed Seif Al-Shamiry, Desa Ahmad, Abdul Rashid Mohamed Sharif et al.Renewable energy sources like photovoltaic (PV) panels are used today in many applications. Natural ventilation in tropical greenhouse is common method for ventilation, which gives higher inside temperatures compared to the outside temperatures. In addition, this type of ventilation is not enough to reduce high temperature inside the structure in low land areas. Thus the requirement of cooling is increased. … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 8,216 accessesView PDFCite
