Faces of Chemistry: Organic solar cells (BASF) – Video 2 (14+)

42 Comments



Hi, my name Is Ingmar Bruder. I’m a research scientist in BASF. So BASF is the largest chemical company
in the world and our business segments are plastics and performance chemicals as for example coatings or functional polymers, functional solutions, as for example construction chemicals and certainly agricultural, and oil and gas. So in the year 2050 is expected that about nine billion people will live on this
planet and most of them want to be mobile and
the question is how to find a way to ensure mobility in a
sustainable and a cost efficient way and one possibility could be to invent
cars which drive by electric engines. So what we’re doing in BASF is we are developing organic photovoltaics, organic solar
cells, and since this is a very complex topic a lot of people from different
professions have to work together for example chemists, quantum chemists
and physicists. So since we are a chemical company and
we will sell materials, chemicals, in the end of the day which can be used to produce organic solar cells we need additionally partners from
industry or from academia, to make systems, to make complete organic photovoltaic systems. Traditional solar cells are made mainly
out of silicon and the reason for that is that it can be processed very well, it conducts very well, and it absorbs light in the right optical range. Here in these labs, my team and myself we are developing
organic photovoltaic devices and basically one of these devices you
can see here and this type of solar cell was also used in
the Smart forvision So the main difference between solar cells based on inorganic
materials for example silicon and organic solar cells is that here
dyes are used to convert light into electricity And BASF has knowledge or a lot of know-how of about over 140
years in inventing in creating new dyes and
what we did here is to invent a new dye class which can
convert light into electricity and the big advantages of these solar
cells are that they can be produced very
cheap, in a very cheap and easy way. You can produce them in any color
basically you want to have and they are transparent. So basically what you’re seeing here are different organic solar cells. You
see if they’re made out of different colors different dyes and they are running a
helicopter as a demonstrator but certainly this is a demonstrator and
for future applications you want to power real devices and how that might look like you can see
here. So basically that’s a mobile phone charger powered by organic transparent solar
cells basically here you see my blackberry and I can put it here on the charger and you can see here the clock appears
which means that my blackberry is charged at the moment. So if you want to design the perfect solar cell it should be black because certainly a black color
is absorbing all the visible light However with organic solar cells we can produce
any color you want to have for aesthetic reasons So if you’re buying nowadays solar cells for
your house you have a guarantee that the solar
cells will live for about twenty years. They’re pretty efficient and you pay something between one euros and two euros per watt peak So what we’re doing actually here in our lab is to increase efficiency of the organic solar cells to increase the
lifetime in order to catch up with existing technologies and even more important that we are
developing here the production mechanism allowing us to produce our solar cells in the end of the day for much cheaper conditions So if we are talking about market
entrance of organic photovoltaics we have to distinguish between different
markets. For example if you’re talking about consumer electronics there will be first products available
probably in the next few years. If we’re talking about construction then
the properties or the issues of the solar
cells are much tougher to handle, for example we have to provide a lifetime of twenty years, we have to provide efficiencies of two
digit values and this will take some more years. So as a scientist you’re not
reproducing things what other people have done before or you’re not waiting for orders. As a scientist you have to be creative, you
have to be foolish and that’s how I am and therefore I like my job.

    That's what I need, You need, We need.

  2. Hilde says:

    So if everybody is going to be foolish

  3. Hilde says:

    So, if everybody is going to be foolish… Then we will get better scientists? 😛 next time i see a scientist, I will told him/her that he/she have to be foolish 😛

  4. Sung-Jin Kim says:

    I found that there are number of chemistry lectures in YouTube.

  5. Sung-Jin Kim says:

    Every Monday, my team have a coffee break. In the end of the coffee break meeting, I want to offer a interesting lecture video in order to shaping member's mind. Moreover, I hope it will be good for improving motivation on research in person.

  6. trevor mushala says:

    please send me information on what dyes are used in the video and what copper ions(which solution)?

  7. baykomious says:

    Beautiful

  8. baykomious says:

    How do you guys hire lol ill have my degree in 5 to 8 years 🙂

  9. Thanuka Dananjaya says:

    they can but the thing is at the initial point of contact with the solar cell large part of light reflect back so the initial layer has to absorb the light that reflects the most and the layers down should follow on

  10. SicaGR says:

    I don't recall them saying they used copper. It's usually Titanium oxide & dye.

  11. pappu rana says:

    it is realy awsm . can you plz upload the same for polymer solar cell?

  12. Dathotness4ya says:

    Wow. He's pretty handsome with a lovely accent.

  13. texture6 says:

    Did they just create a portable photosynthesis device 🙂

  14. Morten Vesterager says:

    This is indeed an interesting technology. I you are interested in learning more about
    organic solar cells, make sure you join the free online Coursera course (https://www.coursera.org/course/opv).

  15. QuranicIslam101 says:

    I am still wondering how they can make it transparent?

  16. Etienne Belley says:

    Wow, you guys are genius! This product is really amazing. I'm wondering, since it is translucent, does it work from both sides? If so ain't that a great plus over other solar panels? Considering that you will make them more affordable, durable and better over time.

    Dear Society, I am by no means a physicist, but all of my adult life I have had ideas toward inventions.and improving current ones. for example why do you people think in such  medieval ways. for example that silly solar car. The way you have those tiny solar openings for the sun to shine through is well so pointless.Think of something so far beyond those silly (little) windows and you might get somewhere.My idea is solar paint NOW that is practical  for every inch of that car would have the potential to produce energy or even solar blankets where one could drape it over a tent in the Arctic at -50 degrees and be able to use the energy to power a decent heater…forever as long as there is the light . Up there 24/7 If anything strikes your fancy  [email protected] have about 100 more

  18. Divina Domingez says:

    wow I really want to try this out… 

  19. Haldun Kantoglu says:

    You're amazing..

  20. PATRICK MCKOWEN says:

    Interesting product — Just like he says, this was two yrs ago, they are playing catch up. No real world numbers given, like how much power produced per square meter or how ever they standardize solar cell measurements and I can't seem to find anymore info on the web page — so have they made any progress in 2 yrs ?? And they need to make them more durable for home and other applications like cars – where is that polymer/chemical experience?? I think this was one of those " get some info out to get our stock prices up" type info videos – and I am not saying that is write or wrong, just that I dislike that strategy.  So many companies releasing info about a product that may be 5 to 10yrs out just to see if it will get the stocks up a point or 2. I want to see more hard, real world numbers and facts, not vague promises — but hey, I guess this is what allot of companies need to do stay ahead….   I wish them luck — sounds like a great product.
    Cheers, Patrick

    Excellent! Good luck!

  22. Bharat Tripathi says:

    very informative video

  23. ahmedshinwari says:

    That animation of photons hitting solar cells and emitting both electrons (-ve charge) and protons (+ve charge), defies laws of quantum physics. Quite powerful actually.

  24. Slup10000 says:

    did he just said he is a fool?

  25. Ariel Crawford says:

    how come solar panels can only capture a limited amount of photons? what percent of photons do these small clear solar panels collect?

  26. hamdi ebrahim says:

    I have gotten a research in solar energ who could help me

  27. Rick Freeman says:

    Solar makes sense: http://www.freemansolar.com/why-solar

  28. xparade0de says:

    Wenn Ihr eine Spiegel Beschichtung aufträgt erhöht das die Effizienz enorm, da nicht genutze Licht und sonstige Partikel noch einmal durch die Elektronendruck generierende Schicht fliegen können

  29. Donald Sleightholme says:

    if the black solar cell was absorbing all visible light wouldn't it be impossible to see through it? 😐

  30. Max J says:

    This video is such a SCAM! This video creates a illusion that the organic solar cell is commercial-able. the fill factor of the inorganic solar cell is now more than 30 percent at least while the current organic solar cell is around 15-16 percent…

  31. Mahdi Jaber says:

    Very helpful, thank you!

  32. Ahmed Jalil says:

    it´s verry good videos

  33. Evgen Mozolevski says:

    Instructions from the Avasva site are perfect for beginners.

  34. Egor Mrinskiy says:

    I think you can make it with Avasva solutions.

  35. Shannan Schisler says:

    With Avasva plans doing something like that was easy.

  36. Easter Stedman says:

    With plans from Avasva you can make it really easy.

  37. Shanna Heckler says:

    You need to make some changes. Check Avasva Solutions if you want to make it right.

  38. Linda Morgey says:

    Try some new solutions from Avasva solutions.

  39. Shantell Amend says:

    With Avasva plans doing something like that was easy.

  40. Divesh Vijayanandakumar says:

    I wonder what the progress is after 6 years 🙂

  41. Muskan Khurshid says:

    Hi sir I'm Muskan ..I'm a bsc student I like this idea very much..I'm making a seminar project on it so pls will u answer me which organic products are used in it ..and what are their function…pls reply
