System description
Dimensionality: D
Sample type: single crystal

Starting materials: CH3NH3PbBr3

Product: CH3NH3PbI3

Description: The hybrid perovskite (CH3NH3PbBr3) was converted at low temperature via anion exchange to produce a CH3NH3PbI3.

Method: I-V Test Device

Description: The I-V characteristics of CH3NH3PbI3 were determined by using a Keithley 2636 source-measure unit, which was coupled to a 60X objective in an inverted microscope. This was performed by with a set up of a 100 ms pulse as the device was electrically contacted a soft probe (Picoprobe T 4-10) coated with indium gallium eutectic (Aldrich).

Comment: The circuit current density and slope of CH3NH3PbI3 were measured.
