Abstract
Abstract Antimony sulfide (Sb 2 S 3 ) is a promising absorber for single‐junction and tandem solar cells. Unfortunately, its quasi‐1D structure holds large void space and complex deep defects, which prepare high‐quality absorber layers and pose a significant challenge. In this work, ethylenediaminetetraacetic acid disodium salt (EDTA‐2Na) is developed as an additive to regulate the reaction kinetics for Sb 2 S 3 deposition. The strong chelating interaction between EDTA‐2Na and Sb 3+ significantly suppresses homogeneous nucleation byproducts and retards the deposition rate of the absorber layer. On the other hand, the SnO 2 /CdS double buffer layers could enhance light transmittance, and herein NH 4 F is…
