    Photovoltaic cells are used to convert the energy of the sun directly into electricity. Anyone could use photovoltaic cells to create energy; however, it does and can take up a large amount of space. The technology could be used in all areas, in rural and urban settings. Edmund Becquerel (a French physicist ) first acknowledged the photoelectric effect in 1839 when certain materials were producing small electric currents when exposed to light. Albert Einstein is responsible for enlightening us upon

    The Advantage of Photovoltaic Cells The power source of Photovoltaic cells is great to use because it converts the solar energy from the sun into electricity directly. Energy is released by positive protons that are freed from the semiconductors. when they are freed this lets out a burst of energy. This is an effective way to produce energy because each individual cell produces 1 - 2 watts of energy. This is a compact way to produce energy because of a solar module. A solar module is a packaged and

    The photovoltaic effect was first reported by Edmund Becquerel in 1839 when he observed that the action of light on a silver coated platinum electrode immersed in electrolyte produced an electric current. Forty years later the first solid state photovoltaic devices were constructed by workers investigating the recently discovered photoconductivity of selenium. In 1876 William Adams and Richard Day found that a photocurrent could be produced in a sample of selenium when contacted by two heated platinum

    CHAPTER 3 PHOTOVOLTAIC SYSTEM AND WIND ENERGY SYSTEM 3.1 Photovoltaic system The photovoltaic system was invented by Edmund Becquerel in 1839. He introduced the fact that some certain materials have small amounts of electric current when they are exposed to sunlight. In 1905, Albert Einstein explained the nature of the light and the photoelectric effect which becomes the main principle for the photovoltaic technology. In 1954, Bell Laboratories first built photovoltaic module In photovoltaic system

    INRODUCTION TO SOLAR ENERGY Solar energy is the energy that we get from sun. Solar energy is most readily source of energy. It does not belong to anybody and hence it is free. It is the most important non-conventional source of energy because it is non-polluting and therefore helps in reducing greenhouse effect. Solar energy is used since prehistoric times. In 1970s after the rise in oil prices, several countries began to formulate many research and development programs to use solar energy more
