Rapid Synthesis of Copper Zinc Tin Sulfide (CZTS) & Lead Perovskite Nanocrystals for Solar Cells & Associated Environmental Nanotoxicity

Copper zinc tin sulfide (CZTS or Cu2ZnSnS4) and lead perovskite (CH3 NH3 PbI3) nanoparticles were synthesized and then transformed to be dispersible in nonpolar solvents through an exchange reaction. These water soluble particles were then added to colonies of common Shewanella oneidensis bacterium and results of the effect of the particles on the bacterium are currently in process.This research was supported by the Undergraduate Research Opportunities Program (UROP)
