Manipulating perovskite structural asymmetry for high-performing self-powered full-stokes polarimetry.

ABSTRACT: Developing direct full-stokes imaging polarimetry is essential for various applications but remains challenging. Perovskites have superior optoelectronic properties and structural diversity, making them ideal candidates for high-performing direct full-stokes polarimetry. However, perovskite suffers low chiroptical activity due to inefficient chiral transfer, which greatly limits its circular-polarization-vector discrimination. These issues urgently require remedy. Here, we demonstrate that perovskites' chiroptical activity is highly related to their structural chiral-distortion extent. We propose using halide mixing to construct asymmetric chiral transfer to heighten its structural chiral-distortion extent. Accordingly, we report a 16-fold increment in the optical chiroptical activity. Fur
