Photovoltaic Solar Cell is an electronic device that converts solar energy into electricity using the photovoltaic effect. The modern age of solar power technology arrived in 1954 while experimenting with semiconductors and accidentally found that silicon doped with certain impurities was very sensitive to light.
The production of electricity with solar energy in the traditional method does not yield enough to be called mass production. Hence, a new way needed to be formulized wherein there was higher efficiency than traditional solar cells. We are conversant with the fact that solar cells absorb the visible light of the sun, though half of the sunís output is made up of infrared light that too strikes the earth and it remains completely un-utilized. That is why only about 30% of the total sunlight can be converted to electricity thus lowering photovoltaic cellsí efficiency. The idea was to generate greater consumable electricity for household and daily livelihood.
A new technology was then put to use wherein the infrared energy is collected and converted to electricity instead of working with the protons from sunrays. Such panels are very good electricity generators as they have the ability to collect more than 80% of the energy and use it for the generation of electricity.
The dye, a zinc phthalocyanine compound, is the one to boost the output of the next generation solar cells. It is called the dye-sensitized solar cell (DSC). While ruthenium-based dye molecules are responsible for capturing visible light, a thin layer of nanocrystalline titanium dioxide produces the electrical current. Titanium dioxide is a common mineral found in paints, toothpaste and sunscreen.
The panels made using this formula are very cheap in their setup and have low maintenance costs too. Recently it has been reported that the volatile substances used as electrolytes have been removed from the cells without reducing their efficiency. The usage of cheap plastics instead of expensive crystalline silicon was the most important factor to slash down cost. These plastic sheets contain billions of nanoantennas that collect the heat energy generated by the sun and other sources could dramatically improve the use of a type of energy we are all aware of. They have reduced the thickness of the layer of molecules on the surface of our nanoparticles that impede the escape of the energy-containing charges that they wish to harvest.
Building an alternative energy system can have numerous ecological and financial benefits, but building such a cost efficient system requires one to know exactly where to buy cheap parts and batteries from, the safety precautions that need to be followed, choosing the location, designing the house and also wiring the system. The only way to achieve that is by following a safe, proven and effective step by step system.
