Structure and ionic conductivity of CuCdCl3

Reversible photo-induced trap formation in mixed-halide hybrid perovskites for photovoltaics

“…This value is similar to the activation energies attributed to halide migration in the perovskites CsPbCl 3 , CsPbBr 3 , KMnCl 3 , CuCdCl 3 , KPbI 3 , CuSnI 3 , and CuPbI 3 , which span the range 0.25-0.39 eV. [23][24][25][26] Light-induced halide migration has also been reported to occur in metal halides such as PbBr 2 and PbI 2 , 27,28 and is the basis for latent image formation in photography using AgI. 29 While halide mobilities in hybrid leadhalide perovskites have not yet been reported, ion conductivities of 7 Â 10 À8 and 3 Â 10 À9 S cm À1 have been reported for KPbI 3 and CuPbI 3 , respectively.…”

Light-Induced Phase Segregation in Halide-Perovskite Absorbers

“…In our lab, the observation that halides phase segregate was the first indication that halides moved significantly in MAPb­(Br x I 1– x ) 3 and led us to hypothesize that halide migration and J – V hysteresis in solar cells could be linked. That other halide perovskites and related metal halides are known to be halide conductors − further corroborates the idea that halides in this system could be mobile. Recent transient absorption measurements support our proposals that phase segregation occurs and that carriers quickly relax into the “trap” state by showing transient bleaches of both a high-band-gap and low-band-gap phase .…”

“…However, the structure of "Cu 2 CdCl 2 " is not of β-CuCl type and the phase transition β-to "/-type structures claimed (e.g. Tetragonal CuCdCl 3 reported by Kuku (1987) does not exist at any temperature (see Fig. Tetragonal CuCdCl 3 reported by Kuku (1987) does not exist at any temperature (see Fig.…”
