DESCRIPTION:The methylammonium lead iodide CH3NH3PbI3 (MAPbI3) perovskites 
 have attracted a lot of attention as a possible absorber material for thin
  film solar cells due to their bandgap energy\, high optical absorption co
 efficients and low-cost solution-processing deposition approaches. MAPbI3 
 perovskite solar cells have evolved with transformative potential with lab
 oratory efficiencies greater than 20%. Perovskite absorber materials are v
 ery inexpensive to synthesize and simple to manufacture\, making them an e
 xtremely commercially viable option. Perovskites of compositional variatio
 ns ABX3 can yield a range of crystal structures\, phases\, and stabilities
 . Here\, we probe perovskites of compositional variations ABX3. We report 
 on the structural and optical properties of these perovskites. Photovoltai
 c (PV) devices were fabricated using these high tolerance factor perovskit
 es. We report we have achieved power conversion efficiencies (PCEs) greate
 r than 21% using the high tolerance factor perovskites investigated. The h
 igh tolerance perovskites were also characterized using synchrotron X-ray 
 absorption near edge structure (XANES) spectroscopy at the National Synchr
 otron Light Source (NSLS) II at Brookhaven National Laboratory (BNL).\n\nS
