Fulleropyrrolidine Interlayers for High Efficiency Perovskite Solar Cells

LEAD INVENTOR:

Todd Emrick, Ph.D.

 
PRODUCT OPPORTUNITIES

•       Perovskite solar cells with 7.5-15.5% better power conversion efficiency (PCE)

 

 
ADVANTAGES

•       Significantly improved PCE

 
TECHNOLOGY DESCRIPTION
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.
