Managing 2D/3D Heterostructure Energy Landscape via ï°-conjugated Organic Cations for Efficient Perovskite Solar Cells
Conjugated organic cations that stabilize perovskite 2D/3D interfaces to boost efficiency and lifetime of perovskite solar cells (24.6% demonstrated).
Organic-inorganic halide perovskite solar cells (PSCs) have seen a rapid increase in their power conversion efficiency in the last few years. However, the long-term stability of the PSCs under operational conditions remains a significant hurdle on the road to commercialization. Current solutions apply passivation layers onto perovskite surfaces but these decrease the efficiency of the solar cell. Purdue researchers have developed multi-functional semi-conducing conjugated ligands with 2D/3D heterostructures in order to passivate the surface defects and to improve the intrinsic stability and power conversion efficiency of the perovskite solar cells. The Purdue researchers have achieved a power conversion efficiency of 24.6% and improved the longevity of the solar cell.
