Organic solar cells
Dec 2nd
Now the use of solar panels has been demonstrated, it can be considered to improve the current concept. The problem with this concept is that the manufacturing of the main raw material of the panels (high-grade pure silicon) is a relatively expensive and energy inefficient process.

Thin-film solar cells
Dec 2nd
Thin film solar cells are a relatively new invention, which will probably make the familiar solar cell unnecessary in the future . It is expected that this new technology will be responsible for a global production of 3,700 MW of energy in 2010 . But what are thin-film solar cells? Read the rest of this entry »
Build own Solar Cell
Dec 1st
Do you own the quick action of solar energy experience? Then using two copper plates, some salt and your own solar cooker! The simple cell works because the semiconducting properties of the material copper (I) oxide (Cu2O), which is formed by heating copper in a moderately oxygen-rich environment (the kitchen).

Solar Cell Band Gap
Dec 1st
For a basic understanding of the functioning of a solar cell, it is important to know what the term really means band gap. It is these material-specific property that explains the behavior of the semiconductor in a solar cell to a large extent. In order to understand this article, some knowledge of both physics and chemistry is required. It is understood that in any event at any level knows what electrons are and what role they play in a material. It is also assumed that you know what an electron volt and a photon is.

Solar Cell Semiconductors
Aug 1st
Knowledge about semiconductors is indispensable for explaining the functioning of a solar cell. A semiconductor is a material which, in terms of conductivity is in between conductors and insulators (see band gap for a more detailed discussion of this). Read the rest of this entry »
Solar cells
Aug 1st
The first solar cells were developed in 1883 by Charles Fritt by covering selenium material layers with a thin layer of gold. This cell had an efficiency of only 1% and was more a “proof of concept”. Read the rest of this entry »
