The solar energy absorbed by the Earth in one year is equivalent to 20 times the energy stored in all fossil fuel reserves in the world and ten thousand times the current consumption. The sun is the only source of organic matter and vital energy of the Earth. Photosynthesis is today the most important use of solar energy, and the only source of organic matter, ie, food and biomass.

The production of electricity from photovoltaic cells is still six times more expensive than that obtained from coal, but only two decades ago was twenty times more. In 1960 the cost of installing a single watt of solar cells, excluding batteries, transformers and other auxiliary equipment amounted to $ 2,000, in 1975 was just 30 in 2004 dollars and $ 2.62 goes to 4.25, depending the amount and type of installation.

If in 1975 the kWh cost more than 7 euros, the current price is between 0.3 and 0.6 euros, which allows the use of photovoltaic cells to produce electricity in remote areas of distribution networks and compete with the alternatives existing as electric generators from petroleum.

The photovoltaic effect is the generation of an electromotive force in a semiconductor device, due to absorption of light radiation. Photovoltaic cells convert light energy from the sun into electrical energy. Throughout the decade the photovoltaic market grew at annual rates above 40%, and there are more than 2,500 megawatts installed worldwide. It is estimated that another 85,000 still to be installed MWp, investing 50,000 million euros, to make photovoltaics competitive in the market, which implies a price of 1 euro per watt.

Currently, most solar cells are monocrystalline silicon of high purity, material obtained from the sand, very abundant in nature. Purification of silicon is an expensive process due to the dependence of the electronic components market, which requires a purity (electronic grade silicon) than that required by the photovoltaic cells. TSKAN produces high-performance photovoltaic panels at its facilities around low quality control standards and performance.
