FABRICATION OF HIGH EFFICIENCY, LOW-TEMPERATURE PLANAR PEROVSKITE SOLAR CELLS VIA SCALABLE DOUBLE-STEP CRYSTAL ENGINEERING DEPOSITION METHOD FULLY OUT OF GLOVE BOX

Scalable crystal engineering

 

ABSTRACT

In this work the scalable Crystal Engineering approach was successfully applied to fabricate the CH3NH3PbI3 absorbing layer on low-temperature planar SnO2 under atmospheric conditions (fully out of glove-box). Photovoltaic characterization showed high-reproducible hysteresis-free planar perovskite solar cells with a maximum power conversion efficiency of 17.6%. The photophysical properties of the PSCs, evaluated by transient photovoltage and photocurrent analysis, showed the excellent capability of SnO2 to extract charge for perovskite. Non-encapsulated n-i-p planar solar cells indicated promising stability under atmospheric conditions, maintaining 90% of the initial efficiency for more than 1000 h. We demonstrate that the scalable air insensitive crystal engineering method is a promising approach for industrialization and fabrication of high efficiency, air-stable, and low-temperature planar perovskite solar cells with high reproducibility fabrication.
