Sun in the Netherlands
Dec 1st
The Netherlands is sunny but cold
If you think Sun, the Netherlands is not the first country you will think. Fickle, dreary and limp back to the most famous and well established features of our moderate maritime climate. Yet solar panels in the famous “cold little frog country” to make good profitable, though as yet there is still a need for government subsidy. Read the rest of this entry »
the Sun
Dec 1st
The Sun (Latin: Sol, Greek Helios) is about 150 million kilometers away our nearest star. The sun is the brightest object in our sky and is the source of almost all sensible heat on Earth. The Sun accounts for some 99% of the mass of the solar system and with a diameter 1,392,000 kilometers represents 109 earths. The Sun has mass terms for approximately 79% percent of hydrogen, helium and 19% from 2% other elements (mainly oxygen, carbon, iron). Read the rest of this entry »
Sunlight

The sunlight that we know, has its origins in the fusion process that takes place inside the Sun. The Sun is the process by “baking up” to an effective surface temperature of around 5500 ° C and sends a result of these temperature radiation, sunlight. If we sunlight with a prism to break up (think of a rainbow), we see that the sunlight from a large number of colors. Specifically, we see high energy (short wavelength) to violet and low energy (long wavelength) red. Read the rest of this entry »
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 »
