摘要
The field of polymer solar cells (PSCs) has seen rapid development after the reports of high-performance photovoltaic materials. Herein, iridium (Ir) complexes (1.5 mol%) are introduced to the polymer backbone of PM6, and a new pi-conjugated polymer PM6-Ir1.5 is developed. Further analysis indicates that this approach can rationally modify the molecular packing order of PM6 to achieve suitable nanoscale morphology, efficient charge transport properties, and reduced carrier recombination losses, and significantly improve the photovoltaic performance of the resulting PSCs based on Y6-C2 as non-fullerene acceptor with good solubility in common solvents. Optimized devices obtain a power conversion efficiency (PCE) of 17.09%, whereas the corresponding devices fabricated using the green solvent achieve a remarkable PCE of 16.52%, which is the highest value reported so far in the literature for non-halogenated PSCs.
