The paper presents a novel D-A-D typed fused-ring perylene diimide (PDI)-based organic small molecule, PDTI1, as a cathode interface layer (CIL) for efficient inverted perovskite solar cells (PSCs). PDTI1 enhances electron transport, improves power conversion efficiency (PCE) to 24.64%, and offers better stability compared to control devices. This work demonstrates PDTI1's superiority as a CIL, providing an alternative for high-efficiency PSCs.

How Paios was used

Paios was used in the study for conducting two key tests: Transient Photocurrent (TPC) and Transient Photovoltage (TPV). These tests were performed in the dark to analyze the characteristics of the solar cells​.
