摘要

Ferroelectric materials provide a new pathway to convert thermal energyinto electricity based on the pyroelectric effect. How to modulate the pyroelectricproperty of ferroelectric materials through UV–light is still an urgentproblem that needs to be solved. Here, a self-powered sensor is demonstratedbased on 0.94(Bi_(0.5)Na_(0.5))TiO_3-0.06Ba(Zr_(0.25)Ti_(0.75))O_3 nanoparticles,exhibiting high output electric performance under temperature variationand UV–light illumination conditions. Compared with a purely pyroelectricsystem, the corresponding current peaks of “UV–light + heating” and“UV–light + cooling” states are 88.6% higher and 37.3% smaller in thecoupled system. The fabricated pyroelectric system shows excellent performancewith detection sensitivities of 0.9 (heating) and 1.48 nA K~(?1) (cooling)with 0.7 × 10~(?3) and 0.2 × 10~(?3) nA lux~(?1) illuminated by 395 nm UV–lightas a temperature sensor. Furthermore, a self-powered sensor that issuitable for detecting both UV–light and temperature variations byrecording the output current signals are demonstrated, which provides abasis for the development of the next generation of UV–light-modulatedferroelectric devices.
