Facile route to freestanding CH(3)NH(3)PbI(3) crystals using inverse solubility

CH(3)NH(3)PbI(3) was found to exhibit inverse solubility at high temperatures in γ-butyrolactone. Making use of this unusual, so far unreported phenomenon, we present a facile method for the growth of freestanding crystals of CH(3)NH(3)PbI(3) from solution without addition of any capping agents or s...

Sumario:CH(3)NH(3)PbI(3) was found to exhibit inverse solubility at high temperatures in γ-butyrolactone. Making use of this unusual, so far unreported phenomenon, we present a facile method for the growth of freestanding crystals of CH(3)NH(3)PbI(3) from solution without addition of any capping agents or seed particles. Large, strongly faceted crystals could be grown within minutes. This finding may aid in understanding the crystallization process of CH(3)NH(3)PbI(3) from solution that may lead to improved morphological control of film deposition for a range of device architectures. Our process offers a facile and rapid route to freestanding crystals for use in a broad range of characterization techniques.
