Abstract

En 中文

• Cs2KInI6 studied using DFT under 0%–6% tensile strain. • Lead-free double perovskite with potential low-toxicity and cost-effective advantages. • Bandgap decreases with strain ( ∼1.94→ 1.44 eV). • Strain improves visible-light absorption (red shift). • Band alignment suitable for water splitting (H2 production) and solar energy and CO2 reduction applications.
