Causes electrochemical reactions that increase their effectiveness between 2% and 11%. A solar cell is capable of converting up to 30% of solar energy into electricity. On a clear day, the incident solar energy per square meter per second is 1000 W.
Researchers from the University of Toledo (Ohio) have found ways to increase energy production of solar cells using red wine to cause electrochemical reactions that raise the photovoltaic potential of these devices.
Solar cells, also known as photovoltaic cells, are constructed using semiconductor elements midway between the conductive materials and insulators. The semiconductor elements at room temperature, have few free electrons, which are responsible for the small conductivity. Solar or photovoltaic cells are diodes (diode is a device that allows the passage of electric current in one direction) constructed of two sheets, a fine that is located on top and a thicker sheet located in the lower. When light falls on the topsheet, communicate its energy photons to electrons, and their reactions are those that create a potential difference between the weak and strong blades diodes. This potential difference is typically 0.5 to 0.6 volts. This solar energy is converted into electrical energy. A solar cell is capable of converting up to 30% of solar energy into electricity. On a clear day, the incident solar energy per square meter per second is 1000 W. Difficulties unresolved However, there are unresolved difficulties that make solar cells less efficient than they theoretically can be and this is the problem solved engineers from the University of Toledo. As the researchers explain in the journal Applied Physics Letters, have harnessed the power differential blades semiconductor to generate electrochemical reactions from red wine. These reactions block the weak diodes and respects strong, getting thus raising the efficiency of the solar cell between 2% and 11%. Red wine is not the only substance able to achieve this effect, but has helped to discover a method to enhance the efficiency of solar cells in two years may be in the market.
