Asymmetric Sulfonyldibenzene-Based Hole-Transporting Materials for Efficient Perovskite Solar Cells: Inspiration from Organic Thermally-Activated Delayed Fluorescence Molecules AITranslate
Abstract AITranslate
Organic thermally-activated delayed fluorescence (TADF) materials have been widely applied in organic optoelectronics, biological oxygen sensing, fluorescence probes, and imaging. Inspired by sulfonyldibenzene-based TADF materials with considerable charge transport abilities and distorted structures, we design and synthesize three sulfonyldibenzene-based molecules (CS-01, CS-02, and CS-03) as hole transport materials (HTMs) for perovskite solar cells (PSCs). The CS series HTMs are endowed with excellent thermal stability, good solubility, and suitable energy level matched with perovskite material. As a result, the CS-01-based PSC devices deliver an impressive power conversion efficiency (PCE) of 19.94% and excellent thermal stability.
