I'm about to spend my next two years investigating DSCs, and happened to remember an old NurdRage video about solar cells. Wouldn't you know it, it's the perfect introduction to the field! Thanks to your simple, experimental approach to chemistry, I have an excellent complement the information I find in my first articles. Many thanks from an long-standing fan! Keep up the good work!

honestly if schools could teach students with these examples in live testing then many students such as myself wouldnt have failed chemistry. i majored in physics but failed terribly in chemistry, my first year of high i never understood it and i dont know how guessing things would make me scrape and pass to move on to the second and third year of highschool, unfortunately in my forth year my luck ran out and i failed, it would have been fascinating to learn chemistry.i wish i can go back and learn it. that was a nice vid man,

I agree, the education system is backwards on math and science. Practical applications should be taught first, followed by theory and formulas. When you see something work, it makes you curious how, and more receptive to the theory side. sitting students in a lecture hall for 6 months working formulas on paper is a complete waste, as no curiosity is generated, therefore the work seems like busywork with no point, and most students zone out.

i have carried a research in DSSC and i used normal float glass since we do not have conductive glass in my country, and after some more new improvements i was able to make a cell of 1V and 0.2 A it is not still as good as the commercial cell but it was a great improvement. i hope to continue this research during my college time as well. If this technology is developed we can solve the power crisis over night.

plastic is a bit more difficult since you can't heat it to the temperatures needed without melting/damaging the plastic. I reccomend going to with ITO glass. In the lab the TiO2 is coated with special surfactants and chemicals that operate better at lower temperatures with plastic. but those chemicals aren't easy to get. Also not all TiO2 is good for this. Anatase type TiO2 is the preferred form over the more common Rutile type.

@NurdRage 13 жыл бұрын
@mouzmaster The detergent helps to spread the TiO2. Normally the TiO2 paste just beads up since the glass is hydrophobic. The detergent makes the paste stick so you can spread a thin layer of it without it pulling itself together into beads. :)

Bravo. I try it to make this cell in three years ago. I got 0,525V. I used the glass for thermopane windows (the windows have an oxide layer on one side - I think is silver oxide) called Low-E For electrolit I used betadine. You can put a paper layer, in the middle, where one side has pencil fill - and this side, with pencil, is over smoked glass.

The original poster asked it if was possible, not if it was practical. You don't need large scale production to test if something is possible. Most research on solar cells is done on samples just a few square centimeters in size. Well within the range of laboratory methods. So... Go for it :)

Hi NurdRage, very well done. I hope this will get many more people interested to play with this stuff... The only thing that is very expensive is the ITO glas , but I think it is the PN layer of this ITO surface versus the TIO2 that actually converts the sunlight into electricity. Thus you might need to find a cheaper semiconductor than ITO coated glas that has about the same bandgap as ITO versus TiO2. Many thanks for this instruction how to build it. Regards, Stefan.

The tape would be too thick. but since this is for demonstration then you can do it, the resulting drop in conductivity and current isn't very much. But i find it not to be a big issue since the titanium dioxide is thick enough and strong enough to hold the glass apart on its own.

@Cickarn white paint usually also has lots of other components like binders, organic additives, solvents etc. thus the quality and reproducibility of the cell is not as good as if you made the paint yourself.

@NurdRage well i cant say fully, but, when we treat the titania it produces excited radical electrons and positive holes withing the anatase structure. these electrons pass through the titania film, which after sintering becomes a glass, this is what carries the current. we have been using methylene blue to test and it works. it is especially effective to dope the titania with WO3 or nitrogen. when is said incorrect i was referring to the cost problem you stated.

I'm no expert on this, but I believe the entire point of using the ITO glass is so you have something that's both conductive and transparent. Conductive to allow the electrons to flow from the dyed TiO2, and obviously transparent so light can reach it. Unless you're referring to the ITO glass that had the carbon layer on it, in which case that was covered in the video. ;)

The detergent contains surfactants. Those reduce surface tension of water and, in this case, prevent the TiO2+H2O mixture from beading on the glass and remain in an uniform thin layer while it's dried and baked. Without detergent (any detergent) the TiO2 paste will form beads/droplets.

@leeofbacup That issue is built into the laws of thermodynamics. There is no way to get more energy out of a cycle than what you put in. Long story as to why that is, but its true. Hydrogen is a great energy carrier, but is not an energy source, unlike how the media portrays it. We first need large sources of energy to make hydrogen. And that's why we need to develop solar cells and other technologies.
