High-performance photodetection is becoming increasingly important for the advancement of technology. Very few materials are available that can respond to light across the ultraviolet to the infrared (IR) range. These materials are very much required for optoelectronic devices. Two-dimensional (2D) layered materials became relevant following the discovery of graphene. Transition-metal chalcogenides belong to the 2D layered material class, as well. The field of optoelectronic applications makes extensive use of them. The current study investigated the photodetector device by doping pure SnS nanoflakes with Fe, Mn, Mg, Pd, and W. These materials were used to create paper-based, flexible, biodegradable electronics through a solvent-free hand-print technique. The Mgdoped SnS photodetector has the highest photo response performance among the devices. With a specific detectivity value of 1.64 × 10 10 Jones and a responsivity value of 52 mA W −1 , the 7% Mg-doped SnS exhibits the best response among the different Mg doping. Extensive on−off cycles were used to assess the switching stability of the device, observing clear photo response and photoswitching behavior. The photoswitching curves of the device as created and the device after 8 months show an amazing degree of consistency, indicating the device's resilience in open-air environments. The device was bent repeatedly to test its twisting, foldability, and flexibility. It continuously displayed a definite photoswitching trend. Testing in a very basic and acidic environment verified the device's chemical stability, and its photo response and photoswitching functions remain functional. When the paperbased photodetector's thermal stability was examined at various temperatures, the findings demonstrated that the device continues to function normally and produce photocurrent. Considering how quickly technology is developing nowadays and how much waste is produced by electronics, switching to paper-based gadgets could help achieve sustainability goals.

Advancements in nanotechnology and materials science have led to the development of a variety of nanogenerator materials with improved properties, making energy harvesting technologies increasingly viable for various applications, such as powering wearable devices, remote sensors, and even small electronic gadgets in the future. The evolution of hybrid materials consisting of polymers and nanoparticles as efficient energy harvesters and energy storage devices is in high demand nowadays. Most investigations on organic ferroelectric P(VDF-TrFE) as a polymer host of polymer nanocomposite devices were primally focused on the β phase due to its excellent electrical properties for various application purposes. Nanofiller is also introduced into the polymer host to produce a polymer nanocomposite with enhanced properties. A brief description of various physical quantities related to ferroelectric, dielectric, pyroelectric effects and Thermally Stimulated Current (TSC) for energy harvesting applications in nanogenerator materials is presented. This article explores the different materials and uses of various nanogenerators. It explains the basics of the pyroelectric effect and the structure of pyroelectric nanogenerators (PNGs), as well as recent advancements in micro/nanoscale devices. Additionally, it discusses how the performance of ferroelectric, dielectric, pyroelectric, and TSC are impacted by the annealing treatment of P(VDF-TrFE) polymer.
