Solar cells, solar cell, photovoltaic, or photovoltaic back the 1970's accept already afflicted our angle on activity and accommodate new avenues for bodies to access electrical activity after afire deposit fuels as the petroleum, accustomed gas or coal, nor with the aisle of nuclear fission. Solar beef can accomplish able-bodied in about all genitalia of the apple tersinari sun, from Morocco to Merauke, from Moscow to Johannesburg, and from mountains to sea level.

 Solar beef can be acclimated after the pollution, both air and complete pollution, and in all weather. Solar beef additionally accept continued been acclimated to accommodate ability for all the satellites orbiting the apple about 30 years. Solar beef accept no affective parts, yet calmly confused as needed.

All the advantages of solar beef on top due to the appropriate characteristics of solar beef that catechumen sunlight anon into electricity. This commodity was advisedly accounting to abode the abounding questions about how the apparatus or alive assumption of solar cells. Accidentally actuality involves alone a qualitative description.

By utilizing solar activity is not terhabiskan, utilizing solar radiation. The afterward analysis of solar radiation that I get from R & D Bulletin of Indonesian aegis ministry. Solar beef fabricated ​​from a actual baby allotment of silicon coated with appropriate chemicals to anatomy the base of solar cells. Solar beef about accept a minimum array of 0.3 mm cavity fabricated ​​from semiconductor abstracts with absolute and abrogating poles. Each solar corpuscle produces a voltage is usually 0.5 volts. Solar beef is an alive aspect (Semiconductor), which utilizes the photovoltaic aftereffect to catechumen solar activity into electrical energy.

General Process is as Follows 

The effect of the electric field in a PV cell

Operation of a PV cell

Basic structure of a generic silicon PV cell
The process of converting light energy into electrical energy
The process of conversion or the conversion of sunlight into electricity is possible because the materials that make solar cells in the form of semiconductor. More precisely composed of two types of semiconductors, ie, type n and type p.

N type semiconductor is a semiconductor that has excess electrons, so that the excess negative charge, (n = negative). While the p type semiconductor has excess holes, so-called p (p = positive) due to excess positive charge. How, by adding another element into the semkonduktor, then we can control the type of semiconductor, as illustrated in the picture below:
 Initially, two types of semiconductor accomplish is advised to access the application akin or adeptness akin of electrical application and thermal accustomed semiconductor. In the accustomed semiconductor (called built-in semiconductors), the electron and aperture accept the aforementioned amount. Excess electrons or holes can access the electrical application and calefaction from a semikoduktor.

For archetype in catechism is an built-in semiconductor silicon (Si). P blazon semiconductor, usually fabricated ​​by abacus the aspect boron (B), aluminum (Al), gallium (Ga) or Indium (In) into the Si. These added elements will access the cardinal of holes. While the n blazon semiconductor is fabricated by abacus nitrogen (N), phosphorus (P) or arsenic (As) into the Si. From here, the added electron can be obtained. Meanwhile, built-in Si itself does not accommodate added elements. Businesses add an added aspect is alleged doping bulk is not added than 1% compared with the abundant Si-doping is activity on.

Two types of semiconductor n and p are taken calm will anatomy a pn alliance or a pn diode (another appellation to alarm with the affiliation metallurgy / Metallurgical junction) which can be declared as follows.

1. P and n blazon semiconductor afore it is dialed.

 2. Shortly afterwards the two types of semiconductors are connected, there is alteration of electrons from semiconductor to semiconductor n p, and the alteration of holes from the semiconductor to the semiconductor p n. Alteration of electrons and holes is alone up to a assertive ambit from the antecedent affiliation limits.
