A “Eureka” for Solar Energy | Bert Conings | TEDxUHasselt

Harnessing sunlight to meet the ever increasing demand for energy at the global scale has long been pursued by scientists and engineers.

During his talk, Dr. Conings will discuss the relevance of solar energy, an everlasting sustainable energy source, that can reduce the dependency on adverse carbon emitting energy resources. Getting at the physical chemistry of burgeoning metal halide perovskites, his talk will focus more deeply on the groundbreaking photovoltaic applications of this state-of-the-art material class, shedding light on their ability to drastically improve global solar energy harvesting.

Harnessing sunlight to meet the ever increasing demand for energy at the global scale has long been pursued by scientists and engineers. Materials scientist Dr Bert Conings, from the Institute for Materials Research (IMO-IMOMEC) at Hasselt University, is among researchers on the vanguard pushing technological boundaries to increase the efficiency of solar energy production. During his talk entitled “A “Eureka” for Solar Energy”, Dr. Conings will discuss the relevance of solar energy, an everlasting sustainable energy source, that can reduce the dependency on adverse carbon emitting energy resources. Getting at the physical chemistry of burgeoning metal halide perovskites, his talk will focus more deeply on the groundbreaking photovoltaic applications of this state-of-the-art material class, shedding light on their ability to drastically improve global solar energy harvesting.

    This year I will take in one ted talk a day instead of all the bad news I took in every morning.

  2. PETER JOHN BRANDAL says:

    He didn't address the attribute of this material to degrade in a matter of days, if not hours. To my knowledge, this remains a problem.

  3. Sado Plays says:

    like it or not, Solar is the future. in near future we will be out of fossil fuel and coal. we will have to improve this technology.

  4. Teddy Keith Loquellano says:

    I was expecting that he would also discuss one major disadvantage of perovskite. They dont last long compared to silicon cells. Perovskite breaks down fairly quick outdoors when exposed to heat, snow, moisture etc. Which is where most of the time we need them to be. I also heard concerns about Perovskites being a toxic material. I feel the talk was being biased vs silicon based solar cells.

  5. Robert McLennan says:

    Research & Development better known as Trial and error! Fix one thing and cause two more problems. But eventually everything gets worked out!

  6. Steven Marsh says:

    If it sounds too good to be true it probably is…

  7. MassDynamic says:

    when you talk about wind energy, you sorta talking about sun energy as well. wind depends on sun

  8. bruh says:

    We need to conserve the fossil fuels to make rocket fuel for space travel because plasma and all that jazz is to expensive.

  9. G Philip C says:

    The Sun…try to live without it.

  10. waltlange says:

    Has a form of perovskite been developed that is not subject to water and sunlight degradation? Isn't the problem with perovskite that it's highly unstable compared to silicon?

  11. Ion-Christopher DiMeglio says:

    Someone asked, "the sun is nuclear, why don't we just use nuclear?"
    BEST REASON is philosophic, based on first principles: Nuclear Energy is Anti-Small. We need distributed / democratic means of production — just like information. And that's not even Marxist — it's just humane. So this is great news about the 'maker' trend line – you think?

  12. Roland Hernandez says:

    Magnificent talk.

  13. relentlessmadman says:

    I personal recommend that you should avoid being trumpesk!! I cannot bare with you I keep my clothes on!!

  14. FlyLowLikeRylo says:

    Exciting technology but this presenter is just so happy with himself that he really detracts from the message.

  15. IncognitoTorpedo says:

    Bert, are you wearing Google Glass, or something like it, or are those just wide frames?

  16. ZachLuscher says:

    This pretty rudimentary explanation. New Material unit cell structures and properties are being discovered everyday to increase efficiency and replace compounds. Perovskites ferroelectric properties are determined by the A and B site bond lengths. It is interesting that the meta stable compounds of ordinarily unstable and non ferroelectric compounds when in octahedral orientation show the most promising electric properties.

  17. Farook Farook says:

    revolutionary idea… Very good presentation

  18. Władca Wymiaru says:

    The source of light is nuclear power. Why not use this power?

  19. Dag Odenhall says:

    Global energy demand is growing by about 2% annually, which translates to a doubling time of about 35 years. The binary logarithm of 3000 gives us about 11.5 doubling periods to get to 3000 times our current energy usage, meaning that in 400 years, covering the planet with solar panels won't be enough to meet demand. We're on our way back to pre-recession demand growths of 5% annually, with a doubling time of 14 years and 160 years before we'd have to cover the whole planet in solar panels. Now I'm not arguing against tapping an available energy source, but it might be useful to understand that relying solely on renewable energy is not sustainable. Inversely, nuclear energy is not renewable but it is sustainable. We need both.

  20. Chris Schene says:

    Generating the power from solar cells is not the engineering problem: The problems that are hard to solve are

    (1) Intermittency
    (2) Storage

    You are generating power only when the sun is shining and hitting your solar cells. Unless you can store the power you will only have power when the sun is hitting your solar cells.
    Battery storage completely negates the savings you get from solar energy
