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
For practical applications, perovskite photovoltaics must deal with stability issues to endure temperature variations because of the phase transition tendency under thermal lattice strain. In recent work published in Science, an ordered dipolar polymer β-poly(1,1-difluoroethylene) was adopted to coat perovskite crystalline grains and align energy levels to endure temperature variations of p-i-n perovskite solar cells. Power conversion efficiency was boosted to 24.6% over 18 mm 2 and 23.1% over 1 cm 2 with no sign of fatigue, showing high operational stability under rapid thermal cycling variations between −60°C and +80°C.
