Stabilizing buried interface by bilateral bond strength equilibrium strategy toward efficient perovskite photovoltaics.

ABSTRACT: The NiO_x/perovskite interface in p-i-n inverted perovskite solar cells (PSCs) suffers from trap-assisted nonradiative recombination, chemical reactions and weak adhesion. The self-assembled molecules are usually designed to address the above issues. However, absonant bilateral bond strength with NiO_x and perovskite hinders the realization of efficient and stable PSCs. Herein, a bilateral bond strength equilibrium strategy is proposed to stabilize the buried interface in inverted PSCs through functional group and spatial conformation engineering. 1-(benzothiaxole-2-ylthio)succnic acid (BTSA) is adsorbed on the surface of NiO_x through the S atom, π-ring, and N atom in the benzothiazole, making benzothiazole ring parallel to the NiO_x surface, which
