The device performance of (R- and S-α-PEA)PbI3 film photodetector. a Schematic diagram of our photodetector. b The responsivity and photoconductor gain of (R- and S-α-PEA)PbI3 device under LCP and RCP light at the wavelengths of 365, 395, 430, and 530 nm. The gray and cambridge blue area denotes the difference of responsivities and photoconductor gain under LCP and RCP irradiation, respectively, with identical intensity. c The wavelength dependent gres spectra. The gCD spectra are also shown here in order to facilitate comparison. d Light intensity dependent LDR and responsivity at 20 V under 395 nm irradiance. The inset is the light intensity dependent photoconductor gain. e Measured current noise at various frequencies. f Normalized response of the photodetector versus the input signal frequency. The -3-dB point is specified with the dash lines
