Solar Photovoltaic Technology the Clean Energy

Solar energy is the clean energy widely used around the globe. The energy from the sunlight is converted into electricity by using the photovoltaic (PV) or Solar cell. Due to huge environmental benefit, various government around the world are focusing on the solar energy development. Due to the long lasting of the photovoltaic system that is 25 to 40 years the popularity is increasing at the rapid rate.

Solar energy can be used without using the photovoltaic. This can be achieved by converting the solar radiation to the single point. This can be achieved using the mirror or lenses. The immense heat produces by converging the light is used to heat the water to convert into the stream. The stream obtained is used for varied purposes.

The importance of the solar energy is drastically improving due to its immense benefits.

Photovoltaic Cell

The photovoltaic cell is often known as the solar cell are the device meant to convert the energy from the light to Electricity by the effect known as the photovoltaic effect.

The light absorption causes the development of election hole and separates into opposite type and external circuit extracts the charge carriers.

The functioning of the photovoltaic cell is an accomplice by the photodetectors, which can detect the electromagnetic range of visible radiation.


Photovoltaic technology uses the wafers to collect the energy. The wafers are the semiconductor material. Using the sheet of glass at the top protects the wafers.

Benefits of Using the Solar Technology

Solar technology has the humongous potential as it harasses the energy from the sun. The rays of the sun are the perpetual form of energy. It implies that solar energy is long lasting or everlasting. Due to less pollution during the manufacturing and operation process, solar technology can be good for ambient atmosphere. Solar technology has the capacity to replace the noisome technology like that from Nonrenewable sources which are the culprit for Environmental degradation.

Due to massive subsidy is given by several governments around the world solar energy technology is becoming cheaper day-by-day. Further, the efficiency has been drastically improved than that of past. Due to higher energy efficiency, the payback period of solar technology has to be minimized to around 10 years.

The drawback of the solar technology

There are series of drawbacks such as high uses of land, less energy efficient, expensive, Further, for optimum performance of solar cell the humidity needs to be considering seriously. The traditionally lead acid battery needs to be replaced every five years that can be expensive to rural households.

Uses of the cadmium in the solar cell can be of great concern due to its danger of bioaccumulation in the food chain.

Father of Communism Karl Marx or Charles Darwin

Communism is the ideology developed by German philosopher and sociologist coined Karl Marx in 1940s. According to the communist ideology, common ownership of good are stressed. Although the root of this tenets dates back to a long time back.
This ideology predicts that property should be handled by the government and need to abolish the private property. Establishing the law and order followed by equality can make the economy of country prosperous.
Communism theory was based on the book by Charles Darwin named origin of species. The book predicts that human beings are the animals and are the by-product of long-term evolution over the thousands of years. Due to this, I will like to call Charles Darwin as the father of communism.

The first application of the communism was done in French where the priests from the church are brutally put to death. It was the unsuccessful revelation. Later Vladimir Lenin from Russia makes the modification in this tenet and did the successful revelation. …

Aghori Baba Living with the Dead Human Body

Aghori Baba is the most fearsome Baba of all Hindu sects. There are less than fifty Aghori Baba in India as well as Nepal due to their arduous and martinet lifestyle. Both the India and Nepal contain more than eighty percent of the Hindu population, which cremate the dead body. Aghori Baba Lives near the cremation ground and did the ritual in Pyre. Due to their practice of cannibalism, this Hindu sect is given the keen interest by westerners. 

This sect claims that by following the martinet lifestyle they are able to liberate themselves from the natural cycle of birth and death. Due to the excessive indulgence with alcohol and marijuana cigarette, they behave abnormally. True Aghori Baba remains active during the night and remains idle during the day. Any Facebook and Mobile number of Aghori Baba is almost all the potential traps.
The origin of Aghori Sects seems hazy. The scent of evidence suggests that a recluse of medieval Kashmir might have inducted this sect. Due to the varied of s…

Metallic Hydrogen: Superconductor Discovery and Skeptics

Hydrogen is the first element of Group 1 of the periodic table and is abundant in nature. They have one proton and one elector. Freezing at 253-degree centigrade hydrogen become liquid and is widely used in Rocket fuel. Under normal atmospheric pressure hydrogen atom pair up to form the hydrogen molecule. The metallic property of the hydrogen is displayed when it loses the electron.
First Hypothesis on Metallic Hydrogen
The scientist named Eugene Wigner and Hillard Bell Huntington, the Princeton physicist hypothesized that massive pressure on the hydrogen turns it into the metal. This was hypothesized in the year 1935 (1). Until now there has not been any successful experiment to test this hypothesis.

Metallic Hydrogen Discovery
The Post-doctorate researcher Dr. Silvera and Ranga P. Dias has published the finding of metallic hydrogen in Journal science. The published journal claims that they have made metallic hydrogen by applying 495 Gigapascals pressure at the temperature -268-degr…
