The paper-based photodetector has recently captivated a great deal of attention in various opto-electronics applications because of facile, cost effective and green synthesis. Two-dimensional transition metal dichalcogenides materials are promising for photodetection under the broad spectral range. In this work, we have fabricated paper-based device by rubbing the tungsten di-selenide (WSe₂) crystals on paper substrate. Low-cost, facile and green synthesis technique was employed to make a high-performance paper-based WSe₂ photodetector. Paper-based photodetector was fabricated via non-toxic simply rubbing process of WSe₂ nanosheets on low-cost bio-degradable paper. The photodetector shows good responsivity of 72.5 μA W⁻¹ and detectivity at around 2.4נ10⁷ Jones at very low bias (1.0 V) at wavelength of 780 nm, respectively. Due to good photo-absorption strength, photodetector exhibits excellent photo-response over wide wavelength range from visible to near infrared. This device also shows very good flexibility with a stable photo-response. This device shows a general and reliable study for the design of photodetectors that is eco-friendly and cost-effective. Overall studied results of the fabricated device indicate that they have the ability to be used in large-scale preparation of the device.
