Recent focus of the research community is on identifying multifunctional materials for the realization of high density energy storage capacitors. Present work focuses on the growth of multifunctional BiFeO₃ (BFO) thin films using Pulsed Laser Deposition technique for the energy storage application. Influence of Laser fluence (150 mJ to 250 mJ) on the energy storage density of BFO thin films has been identified. The enhanced energy storage density of 191 mJ/cm³ has been accomplished for the BFO thin film deposited at 200 mJ incident laser energy, which is higher compared to the earlier available reports. Results indicate that the proper tuning of laser fluence while deposition of BFO thin films is crucial for the realization of optimum energy storage density capacitors.

研究界最近的重点是确定用于实现高密度储能电容器的多功能材料。当前的工作集中在使用脉冲激光沉积技术在能量存储应用中生长多功能BiFeO ₃（BFO）薄膜。已经确定了激光通量（150 mJ至250 mJ）对BFO薄膜的能量存储密度的影响。对于以200 mJ入射激光能量沉积的BFO薄膜，已经实现了191 mJ / cm ³的增强的能量存储密度，这比早期的现有报道要高。结果表明，在沉积BFO薄膜的同时适当调整激光能量密度对于实现最佳储能密度电容器至关重要。
