Reversible photo-induced trap formation in mixed-halide hybrid perovskites for photovoltaics
We report on reversible, light-induced transformations in (CH(3)NH(3))Pb(Br(x)I(1–x))(3). Photoluminescence (PL) spectra of these perovskites develop a new, red-shifted peak at 1.68 eV that grows in intensity under constant, 1-sun illumination in less than a minute. This is accompanied by an increas...
