Les recherches ont transform\u00e9 le syst\u00e8me miraculeux d’auto-nettoyage de la feuille de lotus en une nouvelle m\u00e9thode pour rendre les panneaux solaires plus efficaces.<\/strong><\/em><\/p>\n

Par l’\u00e9quipe d’Unis avec Isra\u00ebl<\/em><\/p>\n

Des chercheurs de l’Universit\u00e9 Ben-Gurion (BGU) ont r\u00e9cemment d\u00e9couvert une nouvelle fa\u00e7on d’optimiser l’\u00e9limination de la poussi\u00e8re des panneaux solaires afin de maintenir l’efficacit\u00e9 et l’absorption de la lumi\u00e8re. Ils ont bas\u00e9 leurs recherches sur les propri\u00e9t\u00e9s autonettoyantes de la feuille de lotus.<\/p>\n

La feuille de lotus, parmi quelques autres plantes, utilise un processus appel\u00e9 \u00abultrahydrophobicit\u00e9\u00bb pour emp\u00eacher l’eau d’entrer, ce qui aide \u00e9galement les feuilles \u00e0 rester exemptes de salet\u00e9.<\/p>\n

\u00abDans la nature, nous observons que la feuille de lotus reste exempte de poussi\u00e8res et d’agents pathog\u00e8nes en raison de sa surface nanotextur\u00e9e et d’un mince rev\u00eatement hydrophobe de cire qui repousse l’eau<\/em>\u00bb, a expliqu\u00e9 Tabea Heckenthaler, \u00e9tudiante \u00e0 la ma\u00eetrise \u00e0 D\u00fcsseldorf en Allemagne au BGU Zuckerberg Institute for Water. Recherche.<\/p>\n

\u00ab\u00a0Dans le d\u00e9sert, la poussi\u00e8re s’accumule \u00e0 la surface des cellules solaires et il faut beaucoup de travail pour les nettoyer en permanence, nous essayons donc d’imiter ce comportement sur une cellule solaire<\/em>\u00ab\u00a0, a ajout\u00e9 le Dr Yair Kaufman, conseiller de l’\u00e9tude. une d\u00e9claration BGU.<\/p>\n

Avec plus de 90% des foyers isra\u00e9liens utilisant des panneaux solaires pour chauffer l’eau, le maintien de leur efficacit\u00e9 est crucial. L’utilisation de l’\u00e9nergie solaire a \u00e9galement augment\u00e9 dans le monde afin de compl\u00e9ter l’utilisation de l’\u00e9nergie conventionnelle.<\/p>\n

La recherche a r\u00e9cemment \u00e9t\u00e9 publi\u00e9e dans une revue \u00e0 comit\u00e9 de lecture de premier plan.<\/p>\n

Remarquablement, 98% des particules de poussi\u00e8re ont \u00e9t\u00e9 \u00e9limin\u00e9es en utilisant la nouvelle technique de l’\u00e9quipe isra\u00e9lienne.<\/p>\n

\u00ab\u00a0Nous avons d\u00e9termin\u00e9 que la raison de l’\u00e9limination accrue des particules n’\u00e9tait pas li\u00e9e \u00e0 un faible frottement entre les gouttelettes et les surfaces superhydrophobes\u00a0\u00bb,<\/em> a d\u00e9clar\u00e9 Heckenthaler. \u00ab\u00a0C’est plut\u00f4t l’augmentation des forces qui peut d\u00e9tacher les particules des surfaces.\u00a0\u00bb<\/em><\/p>\n

L’exp\u00e9rience et le crit\u00e8re d’\u00e9limination des particules utilis\u00e9s peuvent \u00eatre mis en \u0153uvre pour concevoir des surfaces autonettoyantes.<\/p>\n

Les ing\u00e9nieurs isra\u00e9liens sont \u00e0 la pointe de la technologie de l’\u00e9nergie solaire depuis les ann\u00e9es 1950, lorsque le pays a souffert de graves p\u00e9nuries d’\u00e9nergie. Aujourd’hui, la technologie solaire du pays est si avanc\u00e9e qu’elle est presque comp\u00e9titive par rapport aux combustibles fossiles.<\/p>\n

Avec le soleil puissant presque toute l’ann\u00e9e dans le d\u00e9sert du N\u00e9guev pendant la journ\u00e9e, la r\u00e9gion est devenue connue internationalement pour ses recherches et d\u00e9veloppements solaires.<\/p>\n
