Guest repliedSo you guys firm on the idea you cant mix 2 different kinds of solar cells together. -
Unless you can find new and untested materials to construct a more efficient pv cell. That IMO can take billions of dollars and some very sophisticated lab work.Leave a comment:

No, then you'd have an array producing either 4 volts at almost no current, or .6 volts at 6 amps. There is no way you can "trick" physics into supplying more power than is generated from the sum of all the cells you have.
Won't work.What im thinking is I need a Array of these tiny Cells creating 3.60 volts and low amp. And create atleast 1 amp out of array of small cells but high voltage. To push high voltage into my mono cell, so in return in creates high wattage.

Guest repliedYou guys dont mind if I keep asking questions do you?
I mean, the only thing I enjoy doing is tabbing these cells together & on the side I like to do little expirements.
Im sure most tabbing and Bus can handle a bit of current right for just smaller panels I dont have to worry as much even if I dont have spec.
I will have to do some investigating but asking chinese companies who make them sometimes give me the run around or they have no clue what im talking aboutLeave a comment:

I am not sure exactly how much that bus will handle. If you can find the manufacturer they should be a specification on what type of material it is and the amount of current it will transmit but I doubt you will find the amount of electrons it will hold.Leave a comment:

Guest repliedIm so stupid now im sitting in Hot water with this issue..got alot of tabbing and bus and no clue about its spec. other than its thickness.
Ive got two big rolls, no description on them other than
0,2*2mm
And 0.16*18mm
And tabbing for the rolls that have nothing labeled on them
What sort of things would I need to be concered and look for when asking spec sheet or information
and what should I look for from the cells specsLast edited by Guest; 04-06-2016, 09:35 AM.Leave a comment:

Guest repliedSo for example the 5.0x0.2mm solar bus. How much electrons would it hold. Where do I find the spec.
The size of the bus is not the only piece of the puzzle. The material it is made from needs to have the lowest resistance as possible (copper, aluminum, gold, platinum, etc.).
Sometimes the number of wires the "grid" or "mesh" on the cell helps collect more electrons along with the "sheet resistance" of the pv cell material surface will determine how many electrons can be harvested by the "grid" or "mesh" connected to the busbar.
Im way over my head becuase I bought a bunch of solder and tabbing and have no clue about there specs.
I thought it was all determine by thickness.

Dont you just need the thickness of busbar to determin how much current?

You need thickness, material type, and spec for how much heat adjoing parts can withstand, usually the cell will fail, before the tabbing melts.Leave a comment:

No.
You would look at the manufacturer's specifications for the part.How do you find a Tab conductivity to see how much current it can hold.

Guest repliedIs there a way I can add a proton receiver to the conductor. So it can allow the electrons to move to proton device or something rather.

No. You can't add mass to the cell.
Depends on the tab. A conductor can carry a certain amount of current based on its conductivity, cross section and allowable temperature rise. There is effectively no limit to the voltage; that is generally set by the insulation strength and safety regulations.How much Volt and Amp can a tab wire hold. and also Bus.Leave a comment:

Guest repliedSure Im aware of this, Anode and Cathode of Diode. I have plenty of questions that I wrote down. And am Happy you guys are willing to assist me.Solar Cells work by moving either electrons (negative) or spots where electrons would normally be (holes, positive) from one place to another.
Whether you describe the resulting current in electron flow or conventional notation has absolutely no effect on what is happening inside the cells.
Now a diode symbol looks a little bit like an arrow, and if you interpret it as showing the direction that current can flow easily then that corresponds to conventional current.
Is there a way to add protons and neutrons to the solar tab and bus conductors either by external influence of another mechanism.
