Make A Solar Cell - TiO2/Raspberry based

video Make A Solar Cell - TiO2/Raspberry based

In this video we produce dye sensitized solar cell based on titanium dioxide and anthocyanin found in raspberries.

The indium tin oxide glass was purchased from delta technologies http://www.delta-technologies.com/

The titanium dioxide (anatase type) and potassium iodide and iodine were purchased from Alfa Aesar. http://www.alfa.com

I want to know how silicon solar cells are manufactured

Am I the only person that notices the processing on that dude's voice? What's the purpose behind lowering the pitch of your voice?

Regardless, informative video. Hopefully solar cells get more attention so we can use it as a major power source in the near future.

No, in another vid, he said he has a natural low voice.

Just curious, is the glass just coated with the indium tin oxide(or is it like fused to the glass) and if so, is it easy to rub off (like with the use of crocodile clips)?

did i just hear titanium dioxide?

NurdRage (author) says:

its also written in the video description, and spelled out in the subtitles.

Is there a problem?

nevermind, i was gonna say, how does everyone get these chemicals? but i see where, I sorta want the potassium that "reacts" when water is added.

www.unitednuclear.com for all you chemical needs.

I have done this in one of the teaching experiments that I was given to do about half a year ago, it is quite fun to do, and you can compare different kinds of coloring from different kind of fruits/leaves/vegatbles/etc. :)
I want to warn everyone that want's to do this, though: Some of the substances you will be working with are poisonous. If you are not sure if it is, look it up in wikipedia.

Has wikipedia become a reliable reference yet?

Sep 26, 2010. 1:58 AMnieks says:

It isn´t always a reliable resource, but I don´t expect everybody on this site to have a ´handbook of chemistry and physics´ 89th edition or higher. Besides that, everybody that reads this article has internet, and therefore no excuse to not read about the dangers of the chemicals they are working with.
Back to the point of reliability: Wikipedia isn´t always the most reliable, but for chemicals it has links to the ´international chemical savety card´ of those chemicals, which is in fact reliable.

I second that.

¡GREAT, NurdRage! Another masterly lesson of science. I think that Internet has been a quantic jump to the human knowledge, and it is very likely there are hundreds of people working in this matter. The technologic evolution is accelerating more and more, it is awesome. Almost any cheap device that we use today, would have seemed magic only 50 years ago.
