Le march\u00e9 photovolta\u00efque est domin\u00e9 par des modules cr\u00e9\u00e9s \u00e0 partir de cellules solaires \u00e0 silicium mono-jonction, avec des rendements compris entre 17% et 22%. Les communs efforts entre l\u2019Ecole Polytechnique F\u00e9d\u00e9rale de Lausanne (EPFL<\/a>), le Centre Suisse d\u2019Electronique et de Microtechnique (CSEM<\/a>) et le National Renewable Energy Laboratory (NREL<\/a>) ont entra\u00een\u00e9 le d\u00e9veloppement d\u2019une nouvelle cellule photovolta\u00efque \u00e0 base de silicium avec des rendements records. Les cellules solaires multi-jonctions combinent le silicium avec une cellule qui absorbe la lumi\u00e8re bleue du soleil plus efficacement. Les chercheurs ont atteint des rendements de 32,8% pour des cellules \u00e0 double jonction et 35,9% pour celles \u00e0 triple jonction, surpassant ainsi leur record de 29,8%<\/a>.<\/p>\n

Ces r\u00e9alisations, publi\u00e9es dans le journal scientifique Nature Energy<\/a><\/em>, contribueront \u00e0 rendre l\u2019\u00e9nergie solaire plus accessible, comme l\u2019\u00e9voque Christophe Ballif, directeur du centre PV du CSEM et du Laboratoire de photovolta\u00efque de l\u2019EPFL, dans un communiqu\u00e9 de presse<\/a>, \u00ab Ces records prouvent que l\u2019association de silicium cristallin et d\u2019autres mat\u00e9riaux ouvre la voie pour am\u00e9liorer le ratio entre co\u00fbt et le rendement de l\u2019\u00e9nergie solaire \u00bb. Le CSEM travaille activement pour une cellule solaire efficace et rentable et teste actuellement de nouveaux mat\u00e9riaux afin d’optimiser le rapport co\u00fbt \/ efficacit\u00e9 de l’\u00e9nergie solaire. Il est \u00e9galement impliqu\u00e9 dans CHEOPS, un projet de recherche europ\u00e9en visant \u00e0 d\u00e9velopper des cellules photovolta\u00efques peu co\u00fbteuses et extr\u00eamement efficaces bas\u00e9es sur la technologie de la p\u00e9rovskite.<\/p>\n","protected":false},"excerpt":{"rendered":"
