Fig. 1: Experimental setup and evaluation metrics of coupling performance.

a Experimental setup for measuring the coupling of photovoltaic and pyroelectricity. The experiment was measured in a light shield. b Layered structure of the devices based on ferroelectric films. c SEM image of the cross-section of PST ferroelectric film. Scale bar in (c), 200 nm. d Schematic of the current signal upon coupling of the pyroelectric effect (PyE) and photovoltaic effect (PvE). e Schematic of the change in charge and energy before and after coupling of PyE and PvE, and metrics for testing the sequence of coupling performance.
