    We have lived with the sun our entire life and probably most of us take it for granted. But do we realize just how great the sun is and what it can do for us? Our goal is to help you get the most benefit from the sun. Electricity is the lifeblood of modern civilization and we can get as much as we want from the sun. As coal, gas, oil and nuclear energy fuel prices continue to raise solar energy will become even more cost effective. Solar panels are active solar devices that convert sunlight into electricity. They come in a variety of rectangular shapes and are usually installed in combination to produce electricity. The primary component of a solar panel is the solar cells, or photovoltaic cell having low efficiency and high cost. So application of nanotechnology helps us to make solar energy more economical. Nanoscience photovoltaic cells are used to increase the efficiency and to decrease the cost. If nano materials are used in solar panels, solar energy will become even more cost effective over a wider band of solar energy (e.g., including infrared), less expensive so it can be used by more and more people, and to develop more and different uses. The third generation of solar cells is being made from variety of new materials besides silicon, including nanotubes, silicon wires, and solar inks using conventional printing press technologies, organic dyes, and conductive plastics. Black solar cell that absorbs 99.7% of available sunlight. This is a significant improvement over the anti-reflective coatings now used on solar panels.
