· Tl2TeBr6

Tl2TeBr6 is a halide perovskite semiconductor compound containing thallium, tellurium, and bromine. This is an emerging research material in the halide perovskite family, investigated for optoelectronic and photovoltaic applications where lead-free alternatives are needed. While primarily in the experimental stage, materials in this family show promise for next-generation solar cells, X-ray detectors, and radiation sensing because of their tunable bandgap and high charge-carrier mobility, though stability and toxicity concerns require further development before widespread commercialization.
