Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Two structurally similar acceptors ITIC and IT-4F with complementary absorption spectra were employed to construct high-performance ternary blend polymer solar cells (PSCs) by combining a new polymer donor PBTA-PS. The ternary blend solar cell exhibits an outstanding power conversion efficiency of 13.27% with an enhanced short circuit current density (J) of 19.60 mA cm and an excellent fill factor of 74.45%, which is higher than that of PBTA-PS:ITIC (IT-4F) binary solar cells. A wide photoresponse resulting in large J, and good miscibility and compatibility of the three components guarantee the desired morphology and molecular packing in the ternary blend film, which improved the charge transport properties. Our results demonstrated that employing structurally similar acceptors is a promising strategy to enhance the molecular packing and realize high-performance ternary solar cells.
