Abstract

Double perovskite halides Cs2TlGaCl6 and Cs2TlGaBr6 are promising for photovoltaic applications due to their optoelectronic properties. The first-principles density functional theory (DFT) with the HSE06 hybrid functional was applied to systematically investigate their structural stability, electronic structure, optical absorption, and mechanical properties. The calculated tolerance and octahedral factors confirm stable crystal structures. The indirect band gaps of 2.50 eV (Cs2TlGaCl6) and 1.54 eV (Cs2TlGaBr6) are suitable for visible-light harvesting. Strong visible-light absorption and low reflectivity are observed. Elastic constant calculations based on the Voigt–Reuss–Hill approximation validate mechanical stability. The Spectroscopic Limited Maximum Efficiency (SLME) estimates promising photovoltaic efficiencies of 12.41% for Cs2TlGaCl6 and 29.73% for Cs2TlGaBr6 perovskite. These findings highlight the potential of Cs2TlGaCl6 and Cs2TlGaBr6 for low-cost, high-efficiency solar cells, warranting further experimental investigations.
