18 Nov 11 Make a Solar Cell – TiO2/Raspberry based

In this video we show how to make a dye sensitized solar cell based on titanium dioxide and anthocyanin found in raspberries. First get some titanium dioxide (anatase structure), about 0.5g will do. Then mix it with drops of vinegar until it has the consistency of thin paint or liquid…

    Tip of the day : spincoating is really simple to do, and would help a lot for a more regular TiO2 layer.
    Many thanks for all your work, i learnt a lot from your videos, and as a related suggestion, more security advices would be welcome. Could you explain us the basics of chemicals storage ? Which products to keep separate, and so on around this topic ?

    thank u 4 the beautiflul video. . TiO2 present in white paint,toothpaste. 4 dye pomegranate friuit,Red oxide used for rust proof can b used .somone asked why carbonsoot the same purpose it does in dry battery cell(+) betadine is easily available(4 ioidine) i read somewhere adding tincure iodine pot iodide
    u get lelectrolyte soln tri iodide.someone quted polyamide good. conducting resin can b tried.a version of dye solar cell, was invented by Michael Grätzel et .ref wikipedia

    The voltage/amperage the cell produces falls off over time. Is this because the cell is warming up and creating resistance, or is the life of the cell just that short?

    Slowly making one of these. Anyone know where to get cheap ITO glass indium tin oxide in large quantities to make decent sized dye panels? I heard second hand touch screens can be used. Oh yeah by the way Nurd rage , verily you are the god of the chemists all hail!

    how much of these things do you think you would need to charge a rechargeable battery?

    @loling53 From a hobby shop or a chemical distributor, there are many online.

    @NurdRage ok thanks:)

    @mads9621 i haven’t tried it, but i don’t see why not.

    (BTW a small terminology issue: the triodide is actually the redox shuttle, the ethylene glycol is the solvent)

    Could pure glycerol be used instead of ethylene glycol as solvent for the redox shuttle (of course if the iodine and potassium iodide can dissolve in it). ethylene glycole is very hard to get here in Denmark:(

    Great video! I have one question though how would someone combine solar cells to make one big solar panel?

    Thanks Garrett

    I don’t know where to put this comment so i’ll put it here. Does anybody know how you make a laser? i can’t find any good videos on youtube about it. Please help.

    This video is fascinating! I have only one question: have you tested its cycling ability at all? Does it wear out after repeated cycles?

  14. |

    I showed this to my entire class with my teacher watching and they liked it! Great video mate 😀

    @Phantasm911 The soot catalyzes the reduction of triiodide back into iodide.

  16. |

    Could you explain in detail why soot is needed? Is it to block electrons from jumping from the negative to the positive through the electrolyte?

  17. |

    @NurdRage Just a suggestion, anyway, great vid! :)

  18. |

    @TheAverageChannelx i dont have the time or the money.

  19. |

    You told us about all the improvements that can be made, why don’t you (merely a suggestion) make a video with the materials that substitute these and make a powerful cell? Like you said :)

    killer voice :)!

    thanks dude you’re awesome.

    you are a woman

    Great Video!

    i wish my school was more about this and you were my teacher
