Abstract

Lead-free tin-based perovskite solar cells have received great attention due to their promising photovoltaic performance and ecofriendly properties. However, the fast crystallization process and easy oxidation of Sn²⁺ limit the device performance. Herein, a multifunctional zinc ethylphenyl dithiocarbamate (Ze) additive is introduced to tune the crystallization process of tin-based perovskite and suppress the oxidation of Sn²⁺. Meantime, the interaction between Ze and Sn²⁺ can effectively passivate defects and reduce nonradiative recombination. As a result, the Ze-modified solar cells show an efficiency of 4.64% along with excellent long-term stability.
