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
Herein, the electron transport layer (ETL) ZnO in perovskites (PVSK) solar cells (PSCs) has been modified using reduced graphene oxide (rGO) and investigated its impact on the photovoltaic (PV) performance of PSCs. The device with rGO exhibits enhanced performance with a power conversion efficiency (PCE) of 17.08% as compared to the device without rGO layer (15.93%). The improved device performance of rGO-based device is attributed to the faster charge transfer at the PVSK/ETL interface confirmed via steady-state photoluminescence (PL) and time-resolved photoluminescence (TRPL) spectra. The evaluated PV cell parameters indicate that the rGO layer suppresses the recombination losses and accelerates the charge transport in PSCs.
