We show flexible bolometer devices produced entirely using digital inkjet printing on polymer substrates. The bolometers consist of a silver interdigital electrode thermistor covered with a methylammonium lead trihalide perovskite absorber layer which shows good absorber characteristics at visible wavelengths. Both the standalone thermistor and the complete bolometer devices show polymer PTC thermistor-like behavior over a temperature range of 17 to 36 °C, with a change in resistance up-to six orders of magnitude over this temperature range. The addition of the perovskite absorber to the thermistor structure provides the illumination-dependent behavior proper to bolometers.

我们展示了完全在聚合物基材上使用数字喷墨印刷生产的柔性辐射热测量仪设备。辐射热计由覆盖有甲基铵三卤化铅钙钛矿吸收层的叉指式银热敏电阻组成，该吸收层在可见光波长下显示出良好的吸收特性。独立的热敏电阻和完整的测辐射热计设备在17至36°C的温度范围内均表现出类似聚合物PTC热敏电阻的行为，在该温度范围内电阻变化高达六个数量级。在热敏电阻结构中增加钙钛矿吸收剂可提供适合辐射热计的依赖照明的行为。
