	High-performance multispectral&amp;nbsp;photodetectors&amp;nbsp;(PDs) are highly attractive for the emerging optoelectronic applications. In this work, a new broadband PD based on&amp;nbsp;&lt;em&gt;p&lt;/em&gt;-NiO/Ag/n-ITO&amp;nbsp;heterostructure&amp;nbsp;was fabricated by RF&amp;nbsp;magnetron sputtering&amp;nbsp;technique at room temperature. The tri-layered structure offering multispectral detection property was first identified using theoretical calculations based on combined FDTD and Particle Swarm Optimization (PSO) techniques. The crystal structure of the elaborated sensor was analyzed using X-ray diffraction (XRD) method. The device optical properties were investigated by UV–Vis–NIR spectroscopy. The NiO/Ag/ITO heterostructured PD shows a high average absorbance of 63% over a wide spectrum range of [200&amp;nbsp;nm–1100nm]. Compared with NiO and ITO thin-films, the performances of the heterostructured device are considerably enhanced. It was found that the prepared PD with NiO/Ag/ITO heterostructure merges the benefits of multispectral photodetection with reduced&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/materials-science/optical-loss&quot; title=&quot;Learn more about optical losses from ScienceDirect's AI-generated Topic Pages&quot;&gt;optical losses&lt;/a&gt;&amp;nbsp;and efficient transfer of photo-induced carrier. The device demonstrated a high I&lt;sub&gt;ON&lt;/sub&gt;/I&lt;sub&gt;OFF&lt;/sub&gt;&amp;nbsp;ratio of 78&amp;nbsp;dB and an enhanced responsivity under UV, visible and NIR lights (171&amp;nbsp;mA/W at 365&amp;nbsp;nm, 67&amp;nbsp;mA/W at 550&amp;nbsp;nm and 93&amp;nbsp;mA/W at 850&amp;nbsp;nm). The broadband photodetection property enabled by the optimized NiO/Ag/ITO heterostructure opens a new route for the elaboration of low-cost devices that can offer multiple sensing purposes, which are highly suitable for optoelectronic applications.
