Abstract

The bandgap tunability in methylammonium (MA) lead halide perovskites has motivated us to design a photoresistor array made of MAPbI3, MAPbBr1.5I1.5, and MAPbBr3. To pattern devices on the same substrate, a novel method of laser engraving the substrate was employed. In this method, first, an indium tin oxide (ITO) coated plastic substrate was laser engraved to make microchannels with a width of 50-100 µm. Capillary motion force was used to fill each channel with a different solution containing the perovskite precursors. The current-voltage characteristics of each sensor were studied under dark and light conditions. Light-emitting diodes with different wavelengths were used to study the response of each sensor to monochromic lights. The results are promising toward the fabrication of larger arrays of photosensors which potentially can be used for compact and integrated photospectrometers in lab-on-a-chip devices.
激光雕刻法制备碘和溴基钙钛矿光传感器的方法
甲基铵卤化铅钙钛矿的带隙可调性促使我们设计了一种由MAPbI3、mapbbr1.5、i1.5和MAPbBr3组成的光敏电阻阵列。为了在同一基片上制作器件图案,采用了激光雕刻基片的新方法。在该方法中,首先,在氧化铟锡(ITO)涂层的塑料衬底上激光雕刻出宽度为50-100 μ m的微通道。毛细管运动力被用来用含有钙钛矿前驱体的不同溶液填充每个通道。研究了各传感器在黑暗和光照条件下的电流-电压特性。采用不同波长的发光二极管研究了各传感器对单色光的响应。该结果有望用于制造更大的光敏传感器阵列,这些光敏传感器阵列有可能用于芯片实验室设备中的紧凑型集成光谱仪。
