Hot carrier photoluminescence under continuous-wave excitation. a PL spectra of FASnI3 thin film with addition of SnF2 under 405 nm laser diode excitation. The fitting of the carrier temperature is reported with red solid lines. b Hot carrier contribution to the photoluminescence and carrier temperature as a function of illumination intensities reported in term of sun (AM 1.5, 1 sun = 100 mWcm−2)
