Room Temperature Wafer‐Scale Synthesis of Highly Transparent and Conductive p‐Type Sulfur‐Doped Copper Iodide

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Wafer‐scale, room temperature synthesis of S‐doped CuI achieves high‐performance transparent p‐type electrodes. Pre‐doping enables precise control of crystallinity and hole density, yielding 86% transmittance and 75 Ω sq−1 sheet resistance. A record‐high figure of merit of 95 000 MΩ−1 and excellent flexibility across diverse substrates are demonstrated.
