Crystal Growth Promotion and Defects Healing Enable Minimum Open-Circuit Voltage Deficit in Antimony Selenide Solar Cells.

ABSTRACT: Antimony selenide (Sb₂ Se₃ ) is an ideal photovoltaic candidate profiting from its advantageous material characteristics and superior optoelectronic properties, and has gained considerable development in recent years. However, the further device efficiency breakthrough is largely plagued by severe open-circuit voltage (V_OC ) deficit under the existence of multiple defect states and detrimental recombination loss. In this work, an effective absorber layer growth engineering involved with vapor transport deposition and post-selenization is developed to grow Sb₂ Se₃ thin films. High-quality Sb₂ Se₃ with large compact crystal grains, benign [hk1] growth orientation, stoichiometric chemical composition, and suitable di
