ABSTRACT
The solar age began in the 1950s in Bell Laboratories with the development of silicon technology. They described the rst high-power silicon photovoltaic cell with 6% efciency. This cell was much more efcient than the previous selenium solar cell. Due to the energy crisis in 1970, many technologies evolved for producing energy from renewable energy sources and photovoltaic devices. A photovoltaic device or solar cell is a solid-state electrical device that directly converts solar light energy into electricity. The light energy is transmitted in the form of small packets of photons or quanta of light, and electrical energy generated is stored.
