High Open‐Circuit Voltage Wide‐Bandgap Perovskite Solar Cell with Interface Dipole Layer
Wide‐bandgap perovskite solar cells (PSCs) with high open‐circuit voltage (Voc) represent a compelling and emerging technological advancement in high‐performing perovskite‐based tandem solar cells. Interfacial engineering is an effective strategy to enhance Voc in PSCs by tailoring the energy level...
