Quel dommage de ne pas pouvoir stocker cette chaleur et cette \u00e9nergie pour pouvoir l’utiliser quand cela s’av\u00e8re n\u00e9cessaire… enfin la nature est ainsi faite !<\/p>\n
Revenons \u00e0 ce bon vieux soleil …<\/p>\n
En remplacement des cellules photovolta\u00efques classiques on mise beaucoup aujourd’hui sur les cellules photovolta\u00efques organique.<\/p>\n
Celles ci constitu\u00e9es sur base de polym\u00e8re ont l’avantage d’\u00eatre plus fines et plus l\u00e9g\u00e8res que les traditionnelles cellules anorganiques.<\/p>\n
On peut ainsi imaginer de les appliquer sur un auvent, des volets ou sur des stores par exemple.<\/p>\n
<\/p>\n
A ce propos les chercheurs du Centre de recherche en mat\u00e9riaux (FMF) de Fribourg (Bade-Wurtemberg) ont d\u00e9velopp\u00e9 en coop\u00e9ration avec l’Institut Fraunhofer des syst\u00e8mes \u00e9nerg\u00e9tiques solaires (ISE) des cellules atteignant le plus grand facteur de remplissage \u00e0 ce jour pour des solutions organiques.<\/p>\n
Le facteur de remplissage est, \u00e0 c\u00f4t\u00e9 du courant de court circuit et de la tension \u00e0 vide, un important crit\u00e8re de qualit\u00e9 qui d\u00e9finit le rendement de la cellule solaire.<\/p>\n
Bien entendu le rendement est un facteur essentiel mais il en est un autre tout aussi important : le prix de revient !<\/p>\n
Or cette cellule photovolta\u00efque organique dispose d’un grand potentiel d’optimisation, en effet les mat\u00e9riaux organiques choisis sont de tr\u00e8s bons absorbeurs ce qui signifie que la quantit\u00e9 de mati\u00e8re n\u00e9cessaire doit \u00eatre moindre.<\/p>\n
De plus elles peuvent \u00eatre produites par rouleau ce qui augmente d’autant l’int\u00e9r\u00eat du fait de sa souplesse d’application ; enfin ces cellules n’ont pas besoin d’\u00e9lectrode indium – oxyde d’\u00e9tain qui est tr\u00e8s on\u00e9reuse.<\/p>\n
Bref on attend beaucoup de ces nouvelles cellules et on comprend aisement l’int\u00e9r\u00eat suscit\u00e9 par les derni\u00e8res d\u00e9couvertes.<\/p>\n
