The role of cation and anion dopant incorporated into a ZnO electron transporting layer for polymer bulk heterojunction solar cells.

ABSTRACT: Doping is a widely-implemented strategy for enhancing the inherent electronic properties of charge transport layers in photovoltaic devices. A facile solution-processed zinc oxide (ZnO) and various cation and anion-doped ZnO layers were synthesized via the sol-gel method and employed as electron transport layers (ETLs) for inverted polymer solar cells (PSCs). The results indicated that all PSCs with doped ZnO ETLs exhibited better photovoltaic performance compared with the PSCs with a pristine ZnO ETL. By exploring the role of various anion and cation dopants (three compounds with the same Al³⁺ cation: Al(acac)₃, Al(NO₃)₃, AlCl₃ and three compounds with the same Cl^- anion: NH₄Cl, MgCl₂, AlCl
