The visible and near visible (Ultra-Violet and near Infrared) electromagnetic radiation that is emitted by the Sun is termed as Solar Radiation . The solar radiation has a spectral or wavelength, distribution that corresponds to different energy levels, short wavelength radiation has a higher energy than long wave length radiation. These solar radiation convert into useful forms of energy such as "heat and electricity", using a variety of technologies. The technical feasibility and economical operation of these technologies at a specific location depends on the available solar radiation or solar resource. Photovoltaic Effect :- Photo-voltaics are the technology for conversion of solar radiation (sunlight) directly into electricity. A photo-voltaic cell also called a PV or a solar cell is the device used for this purpose. The PV technology has emerged as a promising technology to generate electricity for small applications like lighting and meeting other electric...
