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
This work presents an extensive study of one of the potential alternatives in electron transport material (ETM) for perovskite solar cell (PSC). Reduced cerium oxide (CeO x ) as an electron transport layer (ETL) is studied for different composition of oxygen and analysis with [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) interface layer thickness if stacked in between CeO x ETL and perovskite layer has also been done. A detailed investigation has been carried out, incorporating the mobility of CeO x due to small polaron hopping mechanism at the different composition of x, the effect of variation in doping concentration for CeO x and PCBM have also been studied and the optimum efficiency 18.2% is obtained for PSC. Furthermore, to improve the shortcomings in terms of hysteresis and moisture stability, a device is proposed incorporating carbon nanotube (CNT) layer stacked between perovskite and hole transport layer (HTL) which shows 18.6% conversion efficiency.
