Data confidence 85 high

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This work reports the impact of electron transport layers (ETLs) on the performance of perovskite solar cells (PSCs). The ETLs are based on tin (IV) oxide (SnO2) prepared in different nanostructures. The carrier transport properties of PSCs are systematically characterized and the underlying mechanism for the enhancement in performance of PSCs is found. The strategies for optimizing the interface between the ETL and perovskite are demonstrated, yielding a champion device with a power conversion efficiency (PCE) of 20.8 %.
