The panels contain nanotechnology components designed to increase the efficiency of the receivers. The electricity produced will be used for self-consumption of the company's plant, which produces the collectors in the science park in Rehovot
Mike Splinter, President of Applied Materials Global Company, who is visiting Israel this week, launched (January 20.1.08, 1,000,000) an innovative project, the first of its kind in Israel, in which solar panels will be installed to generate electricity from the sun's energy, in the Applied Materials Israel buildings in the Science Park in Rehovot. The alternative solar energy will serve the activities of Applied Materials Israel, which develops and manufactures quality control and fault detection systems used by all the major chip manufacturers in the world. The project will allow the production of up to XNUMX kilowatt hours of electricity every year.
Details of the unique project were revealed today (January 20.1.08, XNUMX) to President Shimon Peres in his meeting with the president of Applied Materials Worldwide. Splinter reported to the president about the groundbreaking developments of Applied Materials Global in the field of solar energy production systems that have demonstrated an improvement in economic viability, alongside their great contribution to the preservation of the environment. "Israel has a unique combination of technological leadership and a climate that is very suitable for producing energy from the sun, and it can and should be a real leader in the field of producing energy from renewable sources in general and solar energy in particular. Through the installation of the system on the roofs of Applied Materials Israel in Rehovot, we illustrate both the real benefits of clean, safe and reliable solar energy - as well as our commitment as a company to the environment."
Applied Materials Global, which is the world's largest manufacturer of equipment for the semiconductor industry and for the production of flat screens, has become in a short period of time the world's largest manufacturer of production lines for the production of solar energy.
In 2006, the company entered the field of equipment for Photovoltaic (PV) systems that enable the production of electrical energy by absorbing electromagnetic radiation from the sun. The photovoltaic systems contain semiconductors that convert the sun's energy into electrical energy. The company uses advanced knowledge and technologies from the fields of semiconductors and flat screens that make it possible to optimize the process of converting sunlight into energy and reduce the price of electricity production.
The systems of Applied Materials Israel that are developed and manufactured in the science park in Rehovot as well as in the factories of business partners in the north of the country, constitute an infrastructure for the development, planning and production of new generations of smaller, faster and cheaper chips.

Open:
Excessive heat damages the activity of photovoltaic panels and the manufacturer recommends cooling them (by sprinkling some water) on particularly hot days.
In today's collectors - the heat itself is not used to generate electricity, but in the future it will probably happen.
I have a question?
Does the heat generated in a photoelectric collector harm the electric current generated?
Is it only the light that contributes to the creation of the current? Or the heat too?
Is there a desired temperature range that will result in an ideal/maximum current?
Thanks in advance for your help…

Instead of pulling out wrong and misleading sentences, first find out what the thing is that you only guess it is. For example: there is a nice website that will probably interest all of you and its address http://www.howstuffworks.com And as his name is. Search for photoelectric cells or something like that and you will understand what it is.
This is the science site, and as the name suggests it is. This is not YNET. There they react and forget (on a daily basis and forget).
And to the content of the news: a light in my eyes when I read it... a building the size of a private house that supplies itself with clean electricity is world news if I'm not mistaken. Again - in the order of magnitude in question here. Although this is a company for which it is relatively easy to carry out a project of this type, since the financial investment in it is minimal since it is one of its products.
As for the "clean" electricity produced by the photovoltaic cell method, this is perhaps one of the clean/green methods that exist today and will exist in the future.
I see this method as the method with the highest potential for producing electricity in a way that is non-polluting. Indeed, these boards have to be created from something, by such and such machines that require energy. But it is the same with everything else that humans produce. And in fact, this is where the "pollution" phase of this method ends - with the end of production, which again, is no more polluting than production of anything else...like producing, say, an LCD screen.
Only a photovoltaic panel does not require any energy after its manufacture. On the contrary! He is here to start generating energy! And yes, it is not a static product - they keep improving its capabilities - exactly what "Applied Materials" did here and this is one of the reasons for the project: that it has better, more worthwhile photovoltaic collectors.
In summary: 1) These cells work better today than ever before, and they will continue to improve a lot.
2) The reason they are not used in a mass way today is because they are simply expensive to produce today and in relation to their output they are not worthwhile for most applications and consumers.
3) It is not relevant to attribute responsibility for environmental pollution to them. Not in their production, and certainly not afterwards (since they simply do the exact opposite process of polluting, unlike the other methods of energy production including most of those defined as "green").
4) It is not relevant to talk about longevity in these cells. It is not a lamp that burns out after a year, nor a smart one that burns out after eight years. It is a static device - without moving components - very simple with high macroscopic (and microscopically sophisticated) testing as well as works in environmental conditions that are clearly not extreme, and there are many more reasons that can be listed in favor of its survival and including its mode of operation and usefulness.
As far as I'm concerned, you can already conclude on your own, neither dark green nor light green. perfect.
Thanks to the tortured,
Regarding the methods, I once saw a program about building collectors from algae. I don't know if it was a collector for a solar heater or for generating electricity.. My question is does this technology still exist or has it evaporated?
Shimmy
What you don't understand is that generating electricity from light, even though it creates less energy than what is invested in it, it creates it for free.
How?
Simply because sunlight is the energy invested and this energy reaches us anyway and if we don't use it, it will be wasted.
In other words - the energy invested, even though it is greater than the energy produced, is energy that is lost in any case - whether we use it or not.
Hello days,
You are confusing the energy invested in the collector with the energy the collector produces. The law of conservation of energy states that when producing energy you cannot get more energy than was invested in the process. ZA, if the collector produces electrical energy from the light, it cannot produce enough electricity to illuminate an entire city by absorbing light from a street lamp shining on it. On the other hand, if on a clear winter day the collector absorbs energy, it will definitely be able to convert to electricity to one degree or another, depending on its efficiency.
According to what I understood, there is a law in physics (don't trust me, I don't have 12 years of study) that says you can't produce more energy higher than what you invested??? Can be?
And if so, what did we do here? Besides giving a few more millions to our big and rich brothers who have long forgotten us?
To my uncle, if you read the news, the factory in Rehovot where the solar collectors are manufactured will be used to produce energy (probably not yet XNUMX percent) from... solar collectors.
Users and more how to use oil/coal.
When we ask, "Do we use oil?", we do not mean to ask "Is the solar collector a product of fossil fuel".
And the answer to that is (almost always) yes!!!
During the production of a photovoltaic cell, the factory that produces it operates machines that consume energy (as on another production line).
This energy is usually electrical energy (electricity) that originates (in the absolute majority of cases) from the burning of fossil fuels - coal or oil.
Hence, because in every production process of a solar cell, we burn fuel and emit a lot of black into the atmosphere.
So a solar cell is a kind of dark green, very dark.
The solution is institutional investment (countries) in cell research included. So that their creation will consume much less energy than it does today, and that their utilization will be economical for the customer.
No oil is used. Semiconductors are used, it is silicon or germanium with elements from the third or fifth column of the periodic table. Mostly nitrogen or phosphorus
I assume that to produce these solar cells oil is used
Also, these solar cells have a certain life time.
What percentage of kilowatt electricity is really green.
I'm not sure there is a survivor for these things and if there is it depends on how you define her. Basically, it depends on the materials you use. Without going into too much, because my knowledge is also limited, you can choose what is the maximum wavelength that you will absorb according to the materials and the amount of doping of the LMWHs from which you will build the cell. The shorter the wavelength, the more energy the photon you absorb has, and you can reach higher voltages, But you will absorb much less photons, on the other hand if you prefer high current at low voltage, you can use longer wavelengths.
The problem is that a voltaic cell is very dependent on the weather. For example, clouds, seasons, sandstorms can greatly affect the intensity of light that reaches the cells themselves.
I'm pretty sure that's true, but take it with a grain of salt.
What is the utilization percentage of this photoelectric method?
Perhaps it is even better to use a method like David's (to heat water) and with the help of the heat to cause movement that will connect to the dynamo that will generate electricity.
It's simply not cheap to build a photovoltaic cell for energy purposes, and I'm not sure how profitable it is (I have a feeling that its utilization is low..)
Electromagnetic radiation is, in other words, light...
You put two semiconductors, one n-type (negative), and the other p-type. Light is photons, when a photon with a certain energy hits an n-type conductor, it can cause an electron to "jump", and move to a p-type electron. That is, you reach a situation where you have a difference between the amount of charges in each substance (in the beginning the amount in each substance is equal, that is, the number of positive charges is equal to the number of negative charges). The charge difference creates tension between the two layers. By connecting an electric circuit between them, you cause the electrons to return from the P-type conductor to the n-type conductor, and back again, God forbid.
If still not understood, or want more detail
For a more detailed explanation of semiconductors
have fun!
"Production of electrical energy by absorbing electromagnetic radiation from the sun",
What do electromagnetic radiation receptors look like?
How It Works ?
