Ultralow absorption coefficient and temperature dependence of radiative recombination of CH
3NH 3PbI 3 perovskite from photoluminescence
Spectrally resolved photoluminescence is used to measure the band-to-band absorption coefficient α<inf>BB</inf>(ω) of organic-inorganic hybrid perovskite methylammonium lead iodide (CH<inf>3</inf>NH<inf>3</inf>PbI<inf>3</inf>) films from 675 to 1400 nm. Unlike other methods used to extract the absorption coefficient, photoluminescence is only affected by band-to-band absorption and is capable of detecting absorption events at very low energy levels. Absorption coefficients as low as 10-14 cm-1...[Show more]
