    Solar energy can be used for heat generation and electricity supply. According to the International Energy Agency (IEA) solar installations will supply approximately 45% of world energy demand in 2050. This will happen through a wide variety of system configurations for various applications. This paper presents a summary of such systems and applications. The case of novel non-concentrating...

    Dye sensitized solar cells (DSSC) are of great interest for the conversion of solar energy into electrical energy and are future alternatives to silicon solar cells. The increase in conversion efficiency of DSSC depends not only the differences in the conductivities of the transparent layers but on the antireflection of the multilayers and the transmittance of the incident light. Therefore,...

    Despite huge energy potentials in Africa, the energy production costs are high and the consumption is low as compared to other World regions. Less than 40 % of Sub-Saharan Africans have access to electrical energy. Lack of electrical energy hampers the rapid development of the continent. The present yearly economic growth of~ 5-6% will be higher if sufficient electrical energy and...

    Providing a solution to deforestation is an environmental issue for the development of the developing countries, especially those in the south. Yet, a significant part of the forest has disappeared quite rapidly in recent years. Environment problems are compounded by health problems. According to 2012 WHO reports, 1.6 millions of women and children die each year from wood and charcoal smoke....

    Ferroelectric lead compounds having a perovskite structure, such as Pb(Zn1/3Nb2/3)O3 (PZN) [1],
    Pb(Mg1/3Nb2/3)O3 (PMN) [2], and their solid solutions with PbTiO3 (PT), have been investigated
    for high-performance ultrasonic transducer applications [3-4]. The integration of such materials
    as thin films have attracted considerable attention these last years thanks to their...

    Abstract
    PV modules are often considered to be the most reliable component of a photovoltaic system. The alleged reliability has led to the long warranty period for modules up to 25 years. Currently, failures resulting in module degradation are generally not considered because of the difficulty of measuring the power of a single module in a PV system and the lack of feedback on the various...

    Poster

    According to previous studies, PV solar tracking systems can capture 20% to 50% more solar radiation than fixed systems; and the advantage of the solar tracking system is that the yield of photovoltaic panels is increased by 30 to 40% compared to the fixed inclined one. A solar tracker is a device that keeps photovoltaic panels in a perpendicular form to the sun's rays. The objective of this...

    Oral Presentation

    The performance of a photovoltaic (PV) module depends on miscellaneous parameters. Of course, these latter parameters vary from an indoor measurement experiment to an outdoor operation on the field. One of them is the panel’s angle of orientation. In fact, depending on the angle of orientation, the panel can receive more or less irradiance. As many research papers found in the literature...

    A solar powered ultrasound pest control system comprising of the standalone device and the booster units were designed, implemented and their performance evaluated both in laboratories and in farms. The concern of this work is to explore better configuration options which can be applied in large farm type, formulate the mathematical expressions relating the area of ultrasound coverage on a...

    BACKGROUND: In this article, we focus on environmental protection and sustainable development, in particular the control of air pollutants and greenhouse effect (GHG). In a nutshell, the prevalence and impact of the consequences on the atmospheric boundary layer (PBL) and the recurring interests of the PBL study are the understandable aspects of the solutions offered by physicists.

    Located on the Gulf of Guinea and also known as the economic power house of the central African sub-region, Cameroon’s population and industrialization has more than doubled in the last three decades. Douala, Limbe and Kribi are three of its main coastal industrial cities. The rapid increase in the population of these industrial cities, post a problem to energy shortages and distribution...
