a The schematic view of the testing the CBPE device. b Photocurrent density versus the linear polarization angle as tuned by the λ/4 plate under the illumination of 119.20 mW/cm2. Black arrows indicate right- and left-handed circularly polarized light (RCP, LCP). c The photocurrent density as a function of time under LCP-405 and RCP-405 nm and the irradiation of 119.20 mW/cm2. d Experimental asymmetry factors of some reported devices with CBPE. Source data are provided as a Source Data file.
