Fulleropyrrolidine Interlayers for High Efficiency Perovskite Solar Cells
Interface engineering is critical for achieving efficient solar cells.  This invention provides a significant power conversion efficiency (PCE) improvement of fullerene/perovskite planar heterojunction solar cells from 7.50% to 15.48% by inserting a fulleropyrrolidine interlayer between the metal electrode and the electron transport layer. The interlayer enhances recombination resistance, increases electron extraction rate and prolongs free carrier lifetime.cells.
