    So you guys firm on the idea you cant mix 2 different kinds of solar cells together.

    Won't work.


    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.

    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.
    Won't work.

    You 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 about

    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.
    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.

    Im 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 specs

    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.

    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.

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

    No. You can't add mass to the cell.
    How much Volt and Amp can a tab wire hold. and also Bus.
    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.

    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.
    Sure 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.

    Conventional im assuming

    Im trying to find like. A book on electronics, with water pipe analogy of Each electronic peices. like Caps, and JTEF, PNP's that kind of stuff.
