Morphology control of organic halide perovskites by adding BiFeO(3) nanostructures for efficient solar cell

The morphology of perovskite light-absorption layer plays an important role in the performance of perovskite solar cells (PSCs). In this work, BiFeO(3) (BFO) nanostructures were used as additive for CH(3)NH(3)PbI(3) (MAPbI(3)) via anti-solvent method. The addition of BFO nanostructures greatly enhan...

Sumario:The morphology of perovskite light-absorption layer plays an important role in the performance of perovskite solar cells (PSCs). In this work, BiFeO(3) (BFO) nanostructures were used as additive for CH(3)NH(3)PbI(3) (MAPbI(3)) via anti-solvent method. The addition of BFO nanostructures greatly enhanced the crystallinity, grain size and film uniformity of MAPbI(3). As a result, the charge carrier mobility and electron diffusion length increased, leading to the increase of the short circuit current (J(SC)) of PSCs. This work provides a very simple but effective approach to improve the morphology of perovskite layer for efficient PSCs.
