Highly flexible CH3NH3PbI3 micro- and nanowires

CH3NH3PbI3 is known to be very efficient in photon to electron conversion, which makes it extremely popular in opto-electronic applications ranging from solar cells to photodetectors. The material is very brittle in bulk, single crystalline, and thin film forms. Here, we report a high flexibility of...

Description
Summary:CH3NH3PbI3 is known to be very efficient in photon to electron conversion, which makes it extremely popular in opto-electronic applications ranging from solar cells to photodetectors. The material is very brittle in bulk, single crystalline, and thin film forms. Here, we report a high flexibility of it in micro- and nanowires' (marked as NWs) shapes contrary to thin films. This result represents an important step toward applications of this highly performant perovskite in flexible optoelectronic devices. The great suppleness originates from the highly crystalline form of these NWs.
