The present work deals with the study of effect of Sn addition (0%–6% by mole) on the electrocaloric (EC) performance of Ba0.85Ca0.15Zr0.1Ti0.9O3 (BCZT) ceramics. Maxwell's relations in conjunction with data from experimental observations were used for the indirect caloric measurements. Small percentage change with Sn addition is found to increase the EC performance of BCZT ceramics. A peak adiabatic temperature change of 0.84 K (353 K) was predicted for 0–32 kV/cm electric field, significantly higher than pristine BCZT ceramics. A simultaneous increase in specific entropy change was also observed.
