A light‐dependent position‐sensitive detector (PSD) is demonstrated using an active layer of organic–inorganic halide perovskite. The lateral device is demonstrated using indium tin oxide coated glass as common back electrode and gold as the top electrodes. Apart from the linearity and the large span of position sensing range, the PSD response is characterized by a sizable responsivity. The device geometry for PSD also permits a high spatial resolution and transient signal mapping of the lateral photovoltage. These results can be understood in the framework of drift‐diffusion model and offer another valuable use for hybrid perovskite systems.

基于混合钙钛矿的位置敏感探测器

使用有机-无机卤化物钙钛矿的活性层对光依赖位置敏感检测器（PSD）进行了演示。演示了使用氧化铟锡涂层玻璃作为常见的背面电极，并使用金作为顶部电极的横向装置。除了线性度和位置感应范围的大范围外，PSD响应还具有相当大的响应度。PSD的器件几何形状还可以实现较高的空间分辨率和横向光电压的瞬态信号映射。这些结果可以在漂移扩散模型的框架中理解，并为混合钙钛矿体系提供了另一种有价值的用途。
