Avec une méthode solvothermale simple, elle a réussi à produire des nanoparticules d’oxyde de titane pouvant être utilisées dans la composition d’un film de pérovskites. Leur structure réduit les défauts, ce qui induit un meilleur flux des électrons. Des tests de petites cellules solaires à base de nanoparticules ont révélé un rendement de 24.05%. Avec un agrandissement de la surface à environ 24 centimètres carrés, celui-ci se monte encore à 22.72%. \u003C\u002Fp>\u003Cp>\u003Cbr>Image : EPFL\u003C\u002Fp>","under","NULL",[54],{"links_id":55},{"id":56,"anchor":13,"label":57,"color":58,"type":59,"link_external":60,"link_email":13,"link_phone":13,"link_page":61,"link_asset":13},"82ea08ae-ce8f-4d2e-8c5f-fa3fda71bf86","Article de l’EPFL","red","external","https:\u002F\u002Factu.epfl.ch\u002Fnews\u002Fa-solution-to-perovskite-solar-cell-scalability-pr\u002F",[],{"collection":27,"item":39,"id":40,"data":63},{"id":39,"anchor":13,"title":13,"image_width":64,"images":65},"full",[66],{"id":67,"caption":13,"directus_files_id":68},1422,{"id":69,"width":70,"height":71,"focal_point_x":13,"focal_point_y":13,"filename_download":72,"description":13,"title":72,"url":13},"9286eddc-c842-4da2-b91b-81ad19d8ff6b",1000,750,"322-010perowskit_re.jpg",[]]
