Theoretical investigations of electronic and optical properties of double perovskite Cs${}_2$Tl$B{X}_6$ ($B=$ Bi, In; $X=$ Cl, Br, I) for photovoltaic application

Ardimas, Edi Suprayoga

Lead-free double perovskites are gaining attention for photovoltaic (PV) applications due to their long carrier lifetimes, tunable bandgaps, and low toxicity. Using first-principle…
