covek je pitao kako se pravi panel, a odgovor na to je od fotonaponskih celija naravno :) ako misli da pravi same celije, moze od tranzistora ili LED dioda, kao i od foto dioda, fototranzistora i svega sto je PN spoj a moze se izloziti direktno svetlu, ali, tu treba previse materijala da bi se nesto postiglo, ajde recimo da sa panelom metar sa metar popunjenim tranzistorima 2N2222 moze da puni mobilni telefon i to ce ga puniti ceo dan , sto ni malo nije efikasno, a efikasne panele ne moze napraviti u kucnoj radinosti osim ako ne nabavi gotove celije jer ga izadje jeftinije nego da kupuje gotov panel i to ako kupi ceo kontejner celija...

ima na yuotubeu par videa kako neki likovi prave solarnu celiju ali treba biti dobar poznavalac hemije i treba doci do hemikalija ... one varijante sa bakarom folijom su cista prevara , ali postoji varijanta gde se moze napraviti celija od bakarne folije , male efikasnosti, kratkog radnog veka , i uopste se ne isplati kupovati toliko bakra za nesto sto nece nikad da se isplati :)

The 1996 japan Patent is by far the best and the most powerful. The japan patent uses a simple process that has been used for centuries, You simply screen print the negative and positive layers and the contact layers on to a piece of glass plate, it does not matter how thick the glass is. The layers can be sprayed on with a spray gun
and a air compressor, but it is best to Screen print it. Screen printing each layer will make your solar cells last
longer and they will be more efficient
If you do not know what screen printing is, you can learn about this very simple process from the Library.
Also lots of info and supplies can be purchased at your local hobby store or art supply store. You can also buy supply's such as screens and such at a local Screen printing shop. or they can screen print it for you. Screen printing is very simple and cheap to do for you self right in your own home. It may take a little studying but it will be worth it. you can print up as many Solar Cells as you want for just pennies. ( Cover your entire roof
with them. You will have more energy than you will ever need. You can then make money selling electricity back to the electric company which should pay for it self in one to two years. The most expensive part is the deep cycle marine batteries and your inverters. Many are making a nice income every year from this, just by
selling electricity back to the electric company, ask to see if your electric company has that type of program in
your area. most states I heard do.

The Japan method is new and it is not limited to just a glass surface, you can also apply it right onto aluminum or copper sheeting. Look at the 1 st page, see the N type layer #2 this is what the Patent says to
Print first. But if you want to print onto a metal surface the metal surface would be #5 then the 1 st print would
be #4 then let it air dry and then bake at 600 degrees for 3 to 5 minutes.
(Each printed layer can be done this way.) Then your 2nd print would be #3, then you let air dry, then bake, then Print #2 Air dry/bake. Then you must print a Metal grid over #2 then let air dry, (you don't have to bake
the metal print. ) This will be your negative contact, #5 will be your Positive Contact, so what your doing is just simply reversing the printing layer steps. If you have never seen a solar cell the metal grid is like a metal
door screen but with bigger spacing. You can buy a special metal printing ink or mix it your self as the patent says. The ink is simply made up of nickel or silver. Nickel is the cheapest and will work just fine.

Please Notice: You can not manufacture and sell the Japan Solar Cells with out there permission If you want
to leam about Screen Printing we sell a VHS Video for only $29.95
Please send $4 for shipping.

The chemicals that are mentioned in the patent are very easy to get. You can buy them in any QTY from any Chemical supply company look one up in your yellow page phone book. Or check online, search for Chemical Supply Shops or companies.

About Photovoltaics

Photovoltaic (or PV, Solar Cells ) systems convert light energy into electricity. The term "photo" is from the
Greek "phos" which means light. "Volt" is named from Alessandro Volta (1745-1827, He was a pioneer in
the study of electricity. So you could say that" Photo-voltaics is basically light electricity! And is most commonly known as Solar Cells. Solar cell systems are already a very important part of our lives. The simplest systems power many of the small calculators and wrist watches we use everyday. PV power is the
cheapest form of electricity for powering these small devices. There are many ways to make solar cells, and one of the cheapest ways is to screen print them. There are many companies in the USA that are doing this.
Many US Patents have been issued for screen printing solar cells and there are many different chemical inks that can be used. The Japanese Patent is one of many.

Turning Sunlight Into Electricity!


Solar Cells convert light energy into electricity at
the atomic level. It was first discovered in 1839, the process of producing electric current in a solid material with the aid of sunlight wasn't truly under- stood for more than a hundred years.

Throughout the second half of the 20th century, the science has been refined and process has been more fully explained. As a result the cost of these devices has put them into the mainstream of modem energy producers. This was caused in part by advances in technology, where PV conversion efficiencies have been improved.

Solar Cell Materials

The most important parts of a solar cell are the semiconductor layers, this is where the electron current is created. There are a number of different materials available for making these semiconducting layers, and each has benefits and drawbacks. Unfortunately, there is no one ideal material for all types of cells and applications.

In addition to the semiconducting materials, solar cells consist of a top metallic grid or other electrical contact to collect electrons from the semiconductor and transfer them to the external load, and a back contact layer to complete the electrical circuit.
Then, on top of the complete cell is typically a glass
cover or other type of transparent encapsulant to seal the cell and keep weather out, and a anti-
reflective coating to keep the cell from reflecting the light back away from the cell. A typical solar cell consists of a cover glass, a anti-reflective layer, a
front contact to allow the electrons to enter a circuit and a back contact to allow them to complete the circuit, and the semiconductor layers where the electrons begin to complete there voyages!

Scientists in Arizona are using screen-printing, a
technique developed for printing fabrics, paper and to produce plastic, glass and metal solar cells.

The basic materials of a photovoltaic cell (solar cell) are inexpensive. The organic manufactured by Ghassan Jabbour and colleagues at the University of Arizona in Tucson have about 11/4 of the efficiency
of commercial silicon solar cells, which turn 10-20 per cent of light energy into electricity. But, being cheap to produce, they can make up the loss in quantity what they lack in quality. Now the Japan screen printed solar cells are even better than that!

For more info contact: Matsushita Electric Industrial co. LTD, Osaka. Japan


In conventional Screen - printing, a taut piece of screen mesh fabric is stretched over a wood frame,
you can buy the screens already made and the materials from any screen printing shop or screen printing supply company in your area or on the internet. Also you might want to check with your local art store, sometimes they have full kits etc...


The screen is then masked off using masking tape,
For example: a 5" x 5" square area. the screen outside of the masking tape is then coated with a block out
A Screen printing press, the wood frame is the screen



An example of a Silicon cell

liquid or paint, this is so when you apply your semiconducting ink that you mixe, it will go through just the area that you masked off when you apply a rubber squeegee to it. The
screen can then be placed on any table top and hinges attached to the back of the wood frame and the table, this will insure the screen can move up and down. Then get a small wood paint stick and using a small nail, hammer one end to the front side of wood frame. This will be your kick leg and will help keep your screen in an upward position when needed. Take a 5" x 5" piece of glass and place it right under the open 5" x 5" area of the open screen mesh. When the leg is flipped back the screen comes down and you grab
your rubber and wood handled squeegee and with the ink in front of your rubber squeegee pull toward you applying pressure so ink will go through screen, once you have passed by
the 5" x 5" area then flip the screen back up and reverse squeegee to flood the screen for the

dobro, ovde se objasnjava da se moze napraviti solarna celija sito stampom, ali nisam shvatio kakva se boja nanosi ? jel zna neko kakva je to "provodna" boja (semiconductor paint) i gde se to kod nas moze nabaviti ? takodje traju namprovodna stakla koja takodje treba negde nabaviti ali gde kod nas ?

verujem da je kod njih to lako, odes ufarbaru i kazes dobar dan, ja bih da kupim osiromaseni uranijum i popratnu opremu za izradu atomske bombe, ali kod nas je jako malo dobavljaca hemikalija i materijala , pa moze li neko da napise sta nam sve treba od farbi za izradu celije , i sta sve jos i gde to nabaviti ?

Kazete da su komponente srebrani ili bronzani nitrat i valjda varikinu za ves koliko shvatam. Ali kako to da povezem na slici je prikazano kao neko staklo ili plastika i lim savijen u krug i obojen u taj bronzani ili srebrni nitrat to su katoda i atoda. Mene zanima prvo da li ja mogu nesto da kazem jer sam ja stvorio ovu temu. Kako da katodu i atodu spakujem u ono staklo ili plastiku koliko primecujem i da li mi treba malo sunca i lupa koja priblizava sunceve zrake?????

ta spirala je napravljena od bakra, i to treba da budu dve odvojene spirale jedna u drugoj a izmedju treba da je elektrolit.

ja sam iz teksta izvukao da jedna elektroda treba da je od aluminijuma a druga je staklo na koje je nastampan "metal grid" ili ti metalna mrezica sito stampom ali umesto boje koristiti srebrni nitrat ili provodnu farbu, znaci treba da bude u slojevima ali je prvi sloj staklo sa stampom,pa varikina, pretpostavljam da na staklo treba nastampati elektrodu bas kao mrezicu sto tanjih zidova i sto manjih rupica kako bi bila pokrivena velika povrsina a opet da moze svetlo da prodre, zatim ide elektrolit pa aluminijumska ploca i to bi bilo to, samo jos hermeticki zatvoriti i izvuci zice.

ovo ne bi trebalo da je preterano tesko uraditi samo je pitanje koliko se isplati ? koliko je efikasno i koliki je vek trajanja ?
