CH₃NH₃PbI(3-x)(BF₄)x: molecular ion substituted hybrid perovskite.

A molecular ion (BF4(-)) substituted hybrid perovskite CH3NH3PbI(3-x)(BF4)x is synthesized. The substituted perovskite shows significant enhancement in electrical conductivity at low frequencies and improved photoresponse under AM1.5 illumination as compared to the perovskite (CH3NH3PbI3).
