A general approach for nanoparticle composite transport materials toward efficient perovskite solar cells

Chem Commun (Camb). 2017 Oct 5;53(80):11028-11031. doi: 10.1039/c7cc05934e.

Abstract

The design of electron transport layers (ETLs) is crucial to the performance of optoelectronic devices. A composite ETL was constructed to overcome the poor carrier extraction issue in perovskite solar cells, resulting in a maximum PCE of 19.14% with reduced hysteresis. A similar enhancement phenomenon was observed in both devices based on TiO2 and SnO2 ETLs.
