Synergistic Crystallization Modulation and Defects Passivation in Kesterite via Anion-Coordinate Precursor Engineering for Efficient Solar Cells.

ABSTRACT: It has been validated that enhancing crystallinity and passivating the deep-level defect are critical for improving the device performance of kesterite Cu₂ZnSn(S,Se)₄ (CZTSSe) solar cells. Coordination chemistry interactions within the Cu-Zn-Sn-S precursor solution play a crucial role in the management of structural defects and the crystallization kinetics of CZTSSe thin films. Therefore, regulating the coordination environment of anion and cation in the precursor solution to control the formation process of precursor films is a major challenge at present. Herein, a synergetic crystallization modulation and defect passivation method is developed using P₂S₅ as an additive in the CZTS precursor solution to optimize the coordination structure and im
