Influence of Thiazole-modified Carbon Nitride Nanosheets with Feasible Electronic Properties on Inverted Perovskite Solar Cells.

Effective, solution processable designs of interfacial electron transporting layers (ETLs) or hole-blocking layers are promising tools in modern electronic devices, e.g. to improve performance, cost and stability of perovskite-based solar cells. Herein, we introduce a facile synthetic route of thiazole-modified carbon nitride with 1.5 nm thick nanosheets which can be processed to a homogeneous, metal-free ETL for inverted perovskite solar cells. We show that thiazole-modified carbon nitride enables electronic interface enhancement via suppression of charge recombination, achieving 1.09 V in Voc and a rise to 20.17 mA/cm2 in Jsc. Hence, this report presents the successful implementation of a carbon nitride-based structure to boost charge extraction from the perovskite absorber towards the electron transport layer in p-i-n devices.
