Photovoltaics And Their Function In The Future Of Solar Energy

Solar energy is one of the most abundant forms of renewable energy available to the world. Photovoltaic cells are used to convert the energy from the sun into electric power. This is done by a process called the photovoltaic effect. Continue reading and learn about photovoltaics and their role in the future of renewable energy.Solar technology can be characterized by the way that it is captured. The solar radiation is either captured passively or actively. A passive solar capture would be when sunlight is converted without using any form of mechanical device, such as a solarium. While an active solar capture would be a conversion using either mechanical or electrical equipment. In both passive and active capture of solar energy, photovoltaic cells can be used.The photovoltaic effect is best described as a material being subjected to electromagnetic radiation. Voltage is created with the charged material. Alexandre-Edmond Becquerel was the first to notice this effect in 1839.In one year, the amount of solar energy that falls to the surface of the earth is so enormous that it will surpass by double the amount of non-renewable energy sources of coal, oil, natural gas, and mined uranium on the earth. The levels of solar power that can be captured in the world are different, depending on the area that it is being captured in. Areas closer to the equator will capture more solar power.Spacecraft and orbiting satellites were the first to use the photovoltaic cell. The cells are now used for many things including power. A cell module or a solar cell can produce a direct current, and to be used for residential and commercial use, it then needs to be converted to alternating current.Photovoltaic cells or solar panels were expensive to install, but now, with new government incentive programs from various governments worldwide things have changed. Use of solar energy is being widely encouraged. The most recent events have shown that we need to be using solar power now more than we ever have before. Solar panels have also decreased in price just over a period of time in the past few years.Photovoltaic cells were initially used as power for devices like personal calculators, and other types of personal gadgets, but there is now testing for solar roadways. In existence at present are solar parking meters, street lights, emergency phones, and power stations in parts of the world. As the need for renewable energy grows, photovoltaic use will increase in the number of items that are seen every day.
