Tabbing solar cells

[snipersquad100]

I've just started putting together my own solar panel, I've watched videos on you tube which they use flux pens to applay the flux. I don't have a flux pen only   
liquid flux in a bottle which has made a bit of mess on the cell as you can see in the pic. Does anyone know if I can wash this flux off or will it damage the cell?
Thanks.

Isopropyl alcohol or IPA. Also, there are specially made flux removers, all of them stink IMHO. Dont drink the alcohol.

Is that ok to use on a solar cell?

How about acetone or nail polish?

Forget about removing flux from solar cells, been there, done that. Even brushing the surface with IPA, acetone and turpentine substitute didn't do much. Regular flux seems to damage or at least embed itself into the coating of a solar cell. Use a low solid content flux like the Stannol X33S-07i.

For an extra mild method of removing flux, I used to use a 'FIRM' toothbrush, they are a little hard to find, and normal Windex.  Note that I used this on PCBs not solar cells, but, it's super mild and you might need a distilled water cleaning pass after if there is residue.
