Solar energy harvesting using lead-free pyroelectric bulk ceramics: A simulation study

Solar radiation and wind provide the temporal temperature fluctuation for heating and cooling. 0.005La eNa0.5Ba0.5TiO3-0.06BaTiO3-0.002Ta is found as the best suitable material for energy harvesting. The voltage and power output are further improved by tuning operating frequency, load capacitance and resistance.
