Abstract

Pyroelectric solar energy harvesting has been a prominent area of research for the past few years. This study is an attempt to compare different pyroelectric materials for harvesting solar energy. Seven different pyroelectric materials including (NH2CH2COOH)3·H2SO4 (TGS), Sr0.5Ba0.5Nb2O6 (SBN), Ca0.2(Sr0.5Ba0.5)0.8Nb2O6 (CSBN), Pb(Zr0.5Ti0.5)O3 (PZT), polyvinylidene difluoride (PVDF), BaTiO3 and LiTaO3 were studied and compared using finite-element analysis. SBN was found to be the potential pyroelectric material with the maximum storage voltage of 11.47 V across an optimized load capacitance. SBN was subjected to further analysis, revealing an optimum power output of 4.9 μW at the optimized cycle frequency (0.040 Hz), a load resistance of 50 MΩ and a load capacitance of 4.7 μF, while the stored energy was found to be 576.87 μJ.
