Thin filmed photovoltaic power cell - Revolutionary and trustworthy

Solar electricity is making news nowadays as the effective alternative power source and so is the thin filmed solar cell as the helping hand in this movement toward a greener cleaner future. Inspite of 170 years knowing about the principle behind this phenomenon, it took us forty long years to literally develop a solar power cell. From the cell having efficiency of one percent to thin filmed cells having potency surpassing twenty p.c. the technology behind thin filmed solar cell has come an exceedingly long way.

Had there been no advancements made in the domain of solar electricity, we might still be anxious about the exhaustion of non renewable sources of energy. When at first the offer of exploiting solar energy was put forward, it was opposed strongly giving various reasons. One of the debate was the price of installing was far more than the advantages acquired from it and it stayed true until some years ago when thin filmed solar cell was invented.

These solar power cells entirely changed how folk think about solar energy now. It has modernized the whole solar power sector which was once cursed due to its cost coming upto almost five times more as compared to the pollution causing coal and petrol. It has bridged the space between potency and low cost of production of thin filmed solar cell.

Although silicon is in large proportion in the earth's crust in the shape of Silicon dioxide, the silicon required for the manufacture of the standard photovoltaic cells should be awfully pure, obtaining which is really difficult. This adds to the manufacturing cost. This difficulty was disentangled by thin filmed solar cell that have brought a radical reform in this industry.

Thin film solar power cells are prepared by using a extraordinarily thin, about 1 micron thickness, of amorphous silicon on the surface of plastic or flexible metal sheet and then coating it. This reduced the cost as the basis used is very less. Also as the film is very thin, the resistance offered by it to the existing produced is also less. And therefore the energy evaporated in the form of heat energy is also reduced.

Solar cells were extensively employed in solar powered calculators and other small devices that needed a low voltage. But they weren't used on giant scale for household or commercial purposes. This was thanks to the straightforward reason that if the solar panels are used the price of installation is high and the payback time is also long. It was not a wise investment to make but thin filmed solar cell revolutionized the way folk understood about solar cells. Thin filmed photovoltaic cell made the household commercial installation of the solar panels realistic at a particularly minimal cost in comparison to the earlier panels. An energy efficient household or office can run perfectly on the power produced by these thin filmed solar cells.
