Alexander Edmond Becquerel opened the photovoltaic effect in far 1839. In 44 years Charles Fritts managed to construct the first module that could use the solar energy. And selenium coated with thin layer of gold served as the basis then. Scientists have found that this combination of elements makes it possible, albeit marginally (about 1%), to convert solar energy into electricity.

Every day brings many pleasant and not very pleasant surprises to the evolution of humanity. We must pay with something for every progress peak` conquest. All of us know from school the truth about the limitless nature of human needs. Their implementation requires an incredible amount of resources, which are not infinite. Daily, it prompts us to seek new ways to recharge our values that are necessary for the existence of a one, and for pleasure of another. And the issue here is not just about luxury goods, but also about the simple means of life maintaining for each of us. Let us speak, for example, about electricity. Unfortunately, today people no longer notice its absolute dependence on electricity, and hence on its sources, which sometimes simply let us down at the worst possible moment. A striking example is an accident at power plant, when the town is without electricity during few hours. Panic fear, light torches and total helplessness – that is what it means to be without the support of energy for an hour or two. It is a pity, but the person does not always have time to think what would happen next.

In the second half of 20th century the planet’s ecologists became seriously concerned about the problems related to conventional means of electricity production. The problem was the destruction of ecosystems by hydropower plants and nuclear plants waste disposal. In addition, a situation was aggravated by the fact that reserves of fossil fuels (such as oil and gas), by leaps and bounds growing prices, in a couple of decades may dry up altogether. a Major study conducted by analysts and researchers may proof this:

Oil will be the first fuel to be over. There is as huge amount of oil, which is being consumed all over the world annually, as it is formed in natural conditions within 2 million years. We will have enough amounts of Uranus during nearest 64 years, and, fortunately, our grandchildren and even great-grandchildren will be able to use coal.

Natural disasters and climate anomalies have finally confirmed the fears of experts. A man has finally understood that has to look for another way. And let the first technology will be expensive, not as effective, yet safe for nature. Among the many proposed options of transition to a “safe energy”, particular importance is attached to solar energy by scientists. Why?

To find the answer to this question, we must try to figure out whether the solar energy has any opportunity for the future or it does not, what the prospects for the industry are, what is actual the transition to the “solar” technology with in our time for individual consumers.

It is a real gift that we live in the times when the ruling elites start to realize the value of living in harmony with the nature on this planet. And solar power grants is a realistic proof of it.

The history of solar panels can be dated back to 1839 as this was the period when French physicist Antoine-Cesar Becquerel made the astonishing discovery of the photovoltaic effect. This surprising discovery took place during an experiment that involved an electrolytic cell made from two metal electrodes and was placed within an electrolyte solution. Antoine-Cesar Becquerel discovered during the experiment that when the electrolytic cells were exposed to light, it produced a certain amount of electricity. The more the light, the more the production of electricity and that is how solar panels actually came into the picture.

Almost 50 years later in 1883, the first solar cell was developed by Charles Fritts and it was formed using selenium coating sheets with a micro-thin layer of gold. Between the period of 1883 and 1941 there were several scientists as well as inventors who with the help of companies started experimenting with solar energy. It was during this period that Clarence Kemp, an inventor from Baltimore patented the first ever commercial water heater that was being powered by solar energy. Apart from this, the great scientist Albert Einstein also published a thesis on photoelectric effect and within a short period of time received the coveted Nobel Prize for his thesis and valuable research.

Around 1941, an American inventor named Russell Ohl who was working for Bell Laboratories patented the first ever silicon solar cell. This new invention was spearheaded by the Bell Laboratories and they went on to produce the first ever crystalline silicon solar panel in the year 1954. This was the most effective solar cells in that era as it achieved a 4 percent return on overall energy conversion. In the next few years several scientists from all over the world continued their research, study and experimentation to improve upon the original solar cells and started producing solar cells that gave 6% efficiency on overall energy conversion.

The first ever large scale deployment and use of solar energy ever recorded was in space satellites. USA was the first country to enable production of solar cells that gave 20% efficiency and this was in the year 1980. By 2000, USA had produced several solar cells that were producing 24% efficiency. Last year, two large companies, Emcore Photovoltaics and Spectrolab rose to dominate the world of solar cell production by producing cells that gave 28% efficiency.

Working of Solar Panels

The solar panel basically consists of pure silicon. Silicon is first stripped of all its impurities and hence provides the most ideal neutral platform for enhancing the transmission of electrons. In its natural state, Silicon can carry at the max four electrons although it has the ability to carry eight. So mathematically speaking it has enough room for 4 more electrons.

When a silicon atom is made to come into contact with a second silicon atom then each of them receive each other’s extra four electrons. So the 8 electrons satisfy a single silicon atoms’ needs and this results in the creations of a strong bond but the fact is that there are no negative or positive charges. To produce a large piece of pure silicon, the silicon atoms have to go through the process of combination for years. Once the pure silicon is ready, it is applied on to the plates of solar panels. When silicon is combined with other elements then it produces a positive or negative charge.

Solar panels are being looked as the provider of tomorrow as the other forms of creating electricity are getting replenished by the day. There are several online sources and websites who are selling solar panels with a power range that varies from 10WP to 280WP.
