Ainsi, cette collaboration franco-am\u00e9ricaine, incluant deux chercheurs rennais du CNRS et de l\u2019INSA Rennes, vient de mettre en \u00e9vidence que ces mat\u00e9riaux s\u2019auto-r\u00e9parent tr\u00e8s rapidement apr\u00e8s diminution de leurs performances sous rayonnement solaire. Il suffit pour cela de plonger ces cellules solaires quelques minutes dans le noir.<\/p>\n

Les scientifiques ont \u00e9galement propos\u00e9 une hypoth\u00e8se permettant d\u2019expliquer ce ph\u00e9nom\u00e8ne dans leur article publi\u00e9 le 16 mai 2016 dans la revue Nature Communications.<\/p>\n

Les cellules photovolta\u00efques en p\u00e9rovskite, dont les rendements ont explos\u00e9 ces derni\u00e8res ann\u00e9es, deviennent une alternative de plus en plus s\u00e9rieuse \u00e0 celles en silicium qui dominent actuellement le march\u00e9.<\/p>\n
