To harness solar energy, we need the help of another element found abundantly on Earth’s sands. To be used in a solar cell, and needs to be converted into 99.999% pure silicon crystals. To achieve this the sand has to undergo a complex purification.
During the last two decades, the contribution of solar energy to the world’s total energy supply has increased significantly. Energy from the sun is the most abundant and absolutely free energy available on Earth. Solar photovoltaic systems convert solar energy directly into electrical energy. As sunlight strikes a cell in a panel, the cell converts the light into electricity.
