Perovskite solar cells are still unstable due to several internal degradation factors. Most approaches for solving problems of stability and improvement of the efficiency of perovskite cells concern the optimization of the chemical composition of perovskite. An international team of researchers (Italy, Russia) proposed an original approach to design perovskite solar cells with improved performances, namely the use of two-dimensional Titanium-Carbide compounds called MXenes to dope perovskite. They incorporated microscopic amount of MXenes in the perovskite solar cell. As a result, they achieved increase of the efficiency for devices by more than 25 %, compared to the original prototypes…read more. TECHNICAL ARTICLE
