Exceptionally Stable CH3NH3PbI3 Films in Moderate Humid Environmental Condition

چکیده
An unprecedentedly stable CH3NH3PbI3 film synthesized by a modified chemical vapor transport method is demonstrated. The results show that the crystal structure, light absorption, and device efficiency do not degrade after storing for 100 d in air with 40% relative humidity, while the conventional solution-processed perovskites are usually stable for less than 20 d in similar conditions.

Efficient and stable perovskite solar cells prepared in ambient air irrespective of the humidity
Poor stability of organic-inorganic halide perovskite materials in humid condition has hindered the success of perovskite solar cells in real applications since controlled atmosphere is required for device fabrication and operation, and there is a lack of effective solutions to this problem until now. Here we report the use of lead (II) thiocyanate (Pb(SCN)2) precursor in preparing perovskite s...
متن کاملNonstoichiometric acid–base reaction as reliable synthetic route to highly stable CH3NH3PbI3 perovskite film
Perovskite solar cells have received worldwide interests due to swiftly improved efficiency but the poor stability of the perovskite component hampers the device fabrication under normal condition. Herein, we develop a reliable nonstoichiometric acid-base reaction route to stable perovskite films by intermediate chemistry and technology. Perovskite thin-film prepared by nonstoichiometric acid-b...
متن کاملHumidity versus photo-stability of metal halide perovskite films in a polymer matrix.
Despite the high efficiency of over 21% reported for emerging thin film perovskite solar cells, one of the key issues prior to their commercial deployment is to attain their long term stability under ambient and outdoor conditions. The instability in perovskite is widely conceived to be humidity induced due to the water solubility of its initial precursors, which leads to decomposition of the p...

The CH3NH3PbI3 is one of the most widely used and famous lead halide perovskite absorber layer for using in perovskite solar cells. One of the ways to deal with the instability problem of this perovskite structure in environmental condition is bromide doping in this composition. In this work, the structural and optical properties of the bromide doped CH3NH3PbI3 absorber layers were studied as w...
متن کاملHigh-performance perovskite CH3NH3PbI3 thin films for solar cells prepared by single-source physical vapour deposition
In this work, an alternative route to fabricating high-quality CH3NH3PbI3 thin films is proposed. Single-source physical vapour deposition (SSPVD) without a post-heat-treating process was used to prepare CH3NH3PbI3 thin films at room temperature. This new process enabled complete surface coverage and moisture stability in a non-vacuum solution. Moreover, the challenges of simultaneously control...
