Abstract

Here the light responsivity of electrically poled ferroelectric piezoceramics with the composition (0.3) BiFe03- (0.7) Pb0.9sLa0.05 (Zr0.57Ti0.43)0.9875O3 (BFPTZT) through electrical current-voltage (IV) characterizations in dark and 1 Sun (AM 1.5 G) illumination were evaluated. Distinct current features ( 10 nA) are observed from a thin solid pallet in the presence of light than dark, indicating light sensitivity. The material in the finely grained powdered form is introduced in the PEDOT: PSS, a hole transport layer of perovskite solar cell. Both poled, and unpoled samples resulted in different characteristics than the reference devices. The poled-BFPTZT- based device is found to be substantially perturbed with the light exposure and duration with the characteristics resembling memory effect, potentially arising due to the photoactivated domain alignments
