how to make a dye sensitized solar cell HTL Braunau part2

I have a self-made instruction manual in english and german for those cells. You can find the english research paper on scribd - it also includes the instruction sheet:

Feel free to contact me via youtube.

I'd like to say thank you for sharing your video post.. If I may suggest adding some english subtitles, I know i'd find them very useful... but mainly first and foremost thank you for sharing this with us.. I hope you and your team are still working on creative research.. If you have the time I was trying to understand the part of the discoloration and the dye, I got lost on if, one method work better then the other, or if they all suffer from some form of uv sensitivity.. Thanks again :-)

@fobgirl19 I am sorry that it took me so long to answer - well, every dsc is suffering of some sort of uv sensitivity (especially if there is no electrolyte in the cell), but professional cells don't have big problems with it. The most common method to absorb the dye by just putting it into the dye solution. Concerning the biological dyes (hibiscus for example) it degrades under sunlight and becomes invisible (doesn't absorb any visible light anmore). This does not happen to ruthenium dyes.

also when putting the electrodes together, are you placing something in between the cells (it kind of looks like the end of a glass pipette in the video) to allow air to escape from the cell so only the electrolyte solution is left? I find that this step is the hardest to recreate.

[andi742]

@heinles yeah you are right - this step is one of the hardest - no we didn't use a spacer to get the air out of the cell. the only way that i know not to get any air into the cell is to drill two holes into the counter electrode and then fill in the electrolyte with vacuum. afterwards seal the two holes! we always had a few little air bubbles in the cells!

HI! i looked at the website for Gummiwerk Kraiburg, however i was unable to find the rubber solution under their products tab. Do you by chance have a link to a description or order form for this material? Thank you!

@heinles @heinles try to use a two-component epoxy resin or a special glue - works better than the rubber solution that we used for the video

It seems I've already found the answer. According to American Polymer Standards Corporation epoxy resins are soluble only in THF, toluene and chloroform.

Hi, I'll plan to use two-component epoxy resin as a sealant but now I'm not sure whether it is save to use tohether with acetonitrile which is the solvent for my iodine/iodide electrolyte. Could somebody answer me?

[Jacknotzak]

I have a bunch of questions:

Will it work with Povodone-iodine or Potassium triiodide dissolved in water?

Can we substitute a sheet of metal for the conductive glass which is to be covered with soot?

And lastly, can the glass be cleaned and reused to make another solar cell?

(If any of the answers to that were in the pdf, I apologize, because it was really too long to read through.)

@16XDVDLaserDiode thats harsh, they didn't have to post it at all... they even posted a english pdf doc.. they put alot of effort forward to share it on youtube

[heinles]

@andi742 thank you! I also found the link to your paper which was very informative. I finally got some of my practice cells to seal with a mixture of different materials.

Thanks again
