Metric Options: Counts1 Year3 YearSelecting 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
Novel conjugated random and block terpolymers composed of two electron-donating blocks - fluorene (Flo) and carbazole (Cz) - as well as one electron-accepting unit of thiophene-benzothiadiazole-thiophene (TBT) with the same (Flo:TBT:Cz) molar ratio of 0.5:1:0.5 were synthesized. The effects of their microstructure on physico-chemical properties and the performance of photovoltaic conversion were characterized. These conjugated terpolymers displayed two absorption peaks in UV–Vis analysis around 400 and 600 nm with a similar and narrow bandgap (1.9 eV, UV–Vis film), which is suitable to be applied as p-type semiconductors in an organic solar cell (OSC). Both synthesized terpolymers presented a high average molecular weight and degradation temperature above 400 °C. OSCs were assembled for determining the power conversion efficiency (PCE). Block terpolymer with a PCE of 1.3%, higher than that of 0.9% for the random terpolymer, was used as the electron donor in a conventional cell configuration. The device's optimization improved the photovoltaic parameters, mainly the short circuit current density, which allowed a PCE of 3.2% to be achieved. These results demonstrate that the synthesis of block terpolymers is a simple and practical approach for optimizing a conjugated polymer for an efficient OSC.
