Mixed-halide perovskites make great wide-bandgap cells until they segregate. The problem starts at crystallization. A selective Lewis base syncs the mixed halides, yielding stable and efficient perovskite/organic tandem solar cells with a certified 27.0% efficiency.

To investigate the potential of barium-based halide perovskites for optoelectronic applications, we performed first-principles density functional theory calculations on XBaCl 3 (X = In, Tl). These calculations were performed using the WIEN2k package, which provides detailed insights into the materials' characteristics. The code provides a silent insight into materials’ characteristics and potenti…
