3BaO-3TiO2-B2O3 (BTBO) glass-added ferroelectric Ba0.85Sr0.15Zr0.1Ti0.9O3 (BST-BZT) ceramics were synthesized using a conventional solid state reaction route. BTBO glass settled at grain boundaries which has been confirmed from energy dispersive X-ray spectroscopy (EDX). Such effects were observed to benefit properties like the pyroelectric coefficient from 3.4 × 10−4 C/m2 K (0% glass) to 4.29 × 10−4 C/m2 K (2% by wt. glass) at 303 K. The dielectric constant decreased from 2937 to 2514 with 2% glass addition at 303 K (1 kHz). However, this reduction in dielectric constant increases the pyroelectric figure of merits (FOMs) for high current responsivity ( F i), voltage responsivity ( F v), detectivity ( F d), energy harvesting ( F e), and ( F e *) by 50%, 126%, 49%, 81%, and 76%, respectively, for 2% glass sample as compared with 0% glass at 303 K. Some of the FOMs even surpass the reported FOMs of well-known pyroelectric ceramics.
