Perovskiet nieuwste belofte voor doorbraak zonnecellen

AMSTERDAM – Amerikaanse wetenschappers ontdekken de mogelijkheden van perovskiet om te gebruiken in zonnecellen.

Een brok perovskite met een pen erbijVolgens sommige onderzoekers kan het de kosten van zonne-energie omlaag helpen naar 10 tot 20 dollarcent per watt, zo schrijft de MIT Technology Review.

Nu kosten conventionele zonnepanelen ongeveer 75 dollarcent per watt. Energie uit fossiele brandstoffen halen kost ongeveer 50 dollarcent per watt.

Onderzoekers bij onder andere Oxford Photovoltaics hebben testzonnecellen gemaakt die een rendement kunnen behalen van 15 procent. Op termijn zou zelfs 25 procent haalbaar zijn, vergelijkbaar met conventionele kristallijne zonnepanelen van silicium.

Minder kosten en meer beschikbaar 

Het verschil is, is dat perovskiet veel meer beschikbaar is en dat het minder kosten met zich meebrengt in de productie. Verder hoeft een zonnecel van perovskiet minder groot te zijn.

Een gewone siliciumzonnecel is ongeveer 180 micrometer dik. Om hetzelfde rendement te behalen hoeft een zonnecel va perovskiet maar 1 micrometer dik te zijn.

    Los Blancos, with captain Sergio Ramos suspended after deliberately collecting a yellow card in the first leg, had been looking to build on a slender 2-1 lead from that game in Amsterdam and stay on course for a potential fourth straight European triumph.

    However, after Raphael Varane’s header rattled the crossbar, Ajax raced into an early lead through Hakim Ziyech before Dusan Tadic set up David Neres for a second in the 18th minute.

    Real Madrid were forced into two changes when Lucas Vazquez and Vinicius Junior went off injured, with substitute Gareth Bale hitting the post just before half-time.

    Ajax looked to have put the tie to bed when Tadic swept in a brilliant third goal just after the hour – which was eventually given following an extensive Video Assistant Referee review to check if the ball had gone out of play in the build-up.

    These three figures — William Rick Singer, Mark Riddell and Rudolph Meredith, respectively — are at the center of the nationwide scandal in which 33 parents are accused of using their wealth and means to help their children game the college admissions system.
    But those three names do not appear anywhere in the complaint text, though the document gives enough clues to make clear who is who. Instead, they are named as Cooperating Witness 1, 2 and 3, and each agreed to plead guilty and to cooperate with the government in the hope of obtaining leniency when they are sentenced, the complaint says.

    Trump was surrounded at Friday’s event by officials from Customs and Border Protection as well as surviving family members of those who have loved ones killed by undocumented immigrants. Attorney General William Barr was also at the President’s veto event.
    While some lawmakers including some Republicans — have argued against the President’s use of national emergency powers in this instance, the Justice Department set forth a robust defense of the President’s authority to do so in a letter to Senate Majority Leader Mitch McConnell earlier this month, according to a copy obtained by CNN on Friday.
    “The President acted well within his discretion in declaring a national emergency concerning the southern border,” wrote Assistant Attorney General Stephen Boyd, setting out the legal basis for the proclamation under the National Emergencies Act and additional statutory authorities, which largely tracks an internal memo issued by the Office of Legal Counsel at the Justice Department.

    Christina was born in the royal castle Tre Kronor on 18 December [O.S. 8 December] 1626. Her parents were the Swedish king Gustavus Adolphus and his German wife, Maria Eleonora, had already had two daughters—a stillborn princess in 1620, and then the first Princess Christina, who was born in 1623 and died the following year.[note 3] Excited expectation surrounded Maria Eleonora’s third pregnancy in 1626. When the baby was born, it was first thought to be a boy as it was “hairy” and screamed “with a strong, hoarse voice.”she later wrote in her autobiography that, “Deep embarrassment spread among the women when they discovered their mistake.” The king, though, was very happy, stating, “She’ll be clever, she has made fools of us all!”[16] From most accounts, Gustav Adolf appears to have been closely attached to his daughter, and she appears to have admired him greatly.

    Despite residing in Germany for nearly 30 years, there are still some things I cannot wrap my mind around. I may have married a German, pay German taxes, and have German(-American) children, but I guess my US mentality still shines through.

    Like when it comes to personal space. I’ll be standing in the supermarket, in front of a shelf full of products, deliberating over the selection, and inevitably a hand will slip itself in front of my face and grab an item from the row. Many Germans seem to not have any qualms about this at all, but it still takes me aback sometimes.
