Solar Cells
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 »
The Efficiency of Solar Panels
Dec 1st
The efficiency of solar panels depends on many factors. The same panel could therefore perform better in one place than at a different place. This provides a problem for the industry, how to specify the amount of power a solar panel can deliver? The solution has been sought in the unit peak watt (Wp). The power of solar panels is almost always expressed in that unit, the amount of power the solar panel can deliver under ideal conditions (25 ° C in 1000W/m2 intensity). 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 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 »
