Enhancement of the Efficiency of Solar Panel using Concentrator

In the 21st century, there is high demand of energy sources in all over the world. Sun is direct or indirect source of almost every type of renewable energy. Solar Cells or photovoltaic cells are devices which is used to convert solar energy into electrical energy. However, sun is the unlimited source of energy, when exposed to the sun, individual panels cannot generate sufficient amount of energy due to insufficient incident sun rays which demands, number of panels, high installation cost and large land. To solve this problem, we can use Concentrated Photovoltaic Technology, which uses concentrators such as mirrors or lenses to focus sunrays on solar cells for generating electricity with the higher efficiency of individual Solar Panels. But the temperature of the concentrated photovoltaic system will become comparatively very high, therefore in addition to this setup the heat sink and some membrane cooling is used to reduce the temperature of the system. Experimental results have given the significant enhancement in output of the individual solar panel.
