Hexaazatrinaphthylene Derivatives: Efficient Electron‐Transporting Materials with Tunable Energy Levels for Inverted Perovskite Solar Cells
Abstract
Hexaazatrinaphthylene (HATNA) derivatives have been successfully shown to function as efficient electron‐transporting materials (ETMs) for perovskite solar cells (PVSCs). The cells demonstrate a superior power conversion efficiency (PCE) of 17.6 % with negligible hysteresis. This study provides one of the first nonfullerene small‐molecule‐based ETMs for high‐performance p–i–n PVSCs.
