Here, we report on the graphoepitaxial liquid-solid growth of nanowires of the photovoltaic compound CH 3 NH 3 PbI 3 in open nanofluidic channels. The guided growth, visualized in real-time with a simple optical microscope, undergoes through a metastable solvatomorph formation in polar aprotic solvents. The presently discovered crystallization leads to the fabrication of mm 2 -sized surfaces composed of perovskite nanowires having controlled sizes, cross-sectional shapes, aspect ratios and orientation which have not been achieved thus far by other deposition methods. The automation of this general strategy paves the way towards fabrication of wafer-scale perovskite nanowire thin films well-suited for various optoelectronic devices, e.g. solar cells, lasers, light-emitting diodes and photodetectors. | Source Title: | Scientific Reports | URI: | https://scholarbank.nus.edu.sg/handle/10635/182511 | ISSN: | 2045-2322 | DOI: | 10.1038/srep19834 | Rights: | Attribution 4.0 International |
