Comprehensive analytical models for the proposed sensor &lt;a href=&quot;https://www.sciencedirect.com/topics/physics-and-astronomy/photoelectric-emission&quot; title=&quot;Learn more about Photoelectric Emission from ScienceDirect's AI-generated Topic Pages&quot;&gt;photocurrent&lt;/a&gt; and the device properties are developed incorporating the impact of &lt;/span&gt;&lt;em&gt;DM&lt;/em&gt; aspect on the device photoelectrical behavior. The obtained results are validated with the numerical data using commercial &lt;em&gt;TCAD&lt;/em&gt; software. Our investigation demonstrates that the adopted design amendment modulates the electric field in the device, which provides the possibility to drive appropriate photo-generated carriers without an external applied voltage. This phenomenon suggests achieving the dual role of effective carriers’ separation and an efficient reduce of the dark current. Moreover, a new hybrid approach based on analytical modeling and Particle Swarm Optimization (&lt;em&gt;PSO&lt;/em&gt;) is proposed to achieve improved photoelectric behavior at zero bias that can ensure favorable self-powered &lt;em&gt;MSM-&lt;/em&gt;based &lt;em&gt;UV-PD&lt;/em&gt;. It is found that the proposed design methodology has succeeded in identifying the optimized design that offers a self-powered device with high-responsivity (&lt;em&gt;98&amp;nbsp;mA/W&lt;/em&gt;) and superior &lt;em&gt;I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;ON&lt;/em&gt;&lt;/sub&gt;&lt;em&gt;/I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;OFF&lt;/em&gt;&lt;/sub&gt; ratio (&lt;em&gt;480&amp;nbsp;dB&lt;/em&gt;). These results make the optimized &lt;em&gt;MSM-UV-DM&lt;/em&gt;-&lt;em&gt;PD&lt;/em&gt; suitable for providing low cost self-powered devices for high-performance optical communication and monitoring applications.</style></abstract></record></records></xml>
