Des scientifiques viennent d’annoncer une am\u00e9lioration significative des performances de cellules photovolta\u00efques au silicium monocristallin. Ils ont en effet obtenu un rendement de 23.4%.<\/p>\n

La nouvelle est tr\u00e8s int\u00e9ressante puisque qu’elle provient de la tr\u00e8s s\u00e9rieuse Fraunhofer, dont on vous parlait d\u00e9j\u00e0 ici pour des batteries imprimables<\/a>.<\/p>\n

23.4%, c’est consid\u00e9rablement mieux que ce qu’on produit actuellement sur le march\u00e9 (entre 12 et 17%) mais ce n’est pas le record pour le silicium monocristallin. Le record est en effet de 25% de rendement et est d\u00e9tenu par des chercheurs australiens. Quel est donc la nouveaut\u00e9 me direz-vous ? Et bien en r\u00e9alit\u00e9, l’avanc\u00e9e tient dans le fait que cette technologie est beaucoup plus facile \u00e0 mettre en place et beaucoup moins ch\u00e8re que la d\u00e9tentrice du record, tout en affichant des performances l\u00e9g\u00e8rement inf\u00e9rieures mais comparables.<\/p>\n

De plus, on travaille avec du silicium monocristallin, c’est \u00e0 dire qu’on a pas besoin d’\u00e9l\u00e9ments totalement nouveaux par rapport \u00e0 ceux qui sont actuellement utilis\u00e9, si ce n’est pour la mani\u00e8re de doper le silicium. Personnellement 23.4%, \u00e7a m’enthousiasme d\u00e9j\u00e0 beaucoup plus que les performances actuelles. <\/p>\n

Reste \u00e0 savoir l’influence des conditions d’utilisation sur le rendement global de production car c’est \u00e7a au final qui int\u00e9resse le producteur d’\u00e9lectricit\u00e9 solaire. Enfin, aucune date n’est avanc\u00e9e pour la commercialisation d’une telle technologie.<\/p>\n
