摘要：AbstractPyroelectric performance is significantly improved using a coating of diesel exhaust soot. Coated pyroelectric sample (lead zirconate titanate) is exposed to a temporal temperature gradient. Under the application of infrared (IR) heating for a given temperature gradient, the maximum open circuit voltage improves more than four times, electric current across a resistance of 10 ohm improves more than six times, and the stored energy in 10 µF capacitor is enhanced by 17 times. These results are important from two aspects: 1) utilization of waste diesel exhaust soot and 2) improving energy harvesting performance of pyroelectric materials.Significant improvement in performance of pyroelectric materialis observed due to an effective coating of diesel exhaust soot ink. The enhancements in electrical parameters such as open circuit voltage, electric current, and stored energy on application of temperature gradient is presented here. Such results are important in utilizing waste diesel exhaust soot and improving energy harvesting performance of pyroelectric materials.
