However, the basic structures of MSM PPDs include vertical and lateral configurations, which require the use of expensive materials such as transparent conductive oxides or/and sophisticated fabrication techniques such as lithography. Integrating metallic nanowire-based electrodes into the perovskite photo-absorber layer to form one-half of the MSM PPD structure could potentially resolve the key issues of both configurations. Here, a manufacturing of solution-processed and self-powered MSM PPDs with embedded silver nanowire electrodes is demonstrated. The embedding of silver nanowire electrode into the perovskite layer is achieved by treating the silver nanowire/perovskite double layer with a methylamine gas vapor. The evaporated gold layer is used as the second electrode to form MSM PPDs. The prepared MSM PPDs show a photoresponsivity of 4 10􀀀5 AW􀀀1 in the UV region and 2 10􀀀5 AW􀀀1 in the visible region. On average, the devices exhibit a photocurrent of 1.1 10􀀀6 A under white light (75 mW cm􀀀2) illumination with an ON/OFF ratio of 83.4. The results presented in this work open up a new method for development and fabrication of simple, solution-processable MSM self-powered PPDs.enAttribution-NonCommercial-ShareAlike 3.0 United StatesType of access: Open Accessperovskitesilver nanowiresphotodetectornetworkmethylamineArticle
