Solution-processing interface layers for high performance perovskite solar cells

Abstract

In this talk, we demonstrate a high-efficiency inverted planar perovskite solar cell, obtained with a simple wet-chemistry based, room-temperature, and cost-effective processing. The resulted best cell with a FF as high as 80.7% and a remarkable improvement PCE of ~16%, which exceeds the PCE of a device without the interface layers (~11.2%).
