“…The RC time constant measured here is the product of resistance and capacitance of the parallel electrical equivalent circuit model for MAPbI 3 -based photodetectors. 31 As shown in Figure S5, the RC are around 100 ns and four PDs show similar RC time constants. The working area, instead of the thickness, may have a greater influence on the RC of the PD structure here.…”

The photodetector based on methylammonium lead iodide (MAPbI3) is a promising device for wide wavelength range (380–780 nm) sensitivity. However, its industrial application is limited by the relatively low response speed to the light signal, which has received little attention. Only a few reports show low-bandwidth characteristics (less than 1 MHz at 0.1 cm2). Here, when a cosolvent strategy to manipulate the thickness and the crystallinity of the MAPbI3 film is adopted, photodetectors with a −3 dB bandwidth of 4.7 MHz are achieved (at 0.16 cm2 photo detecting area). The performance is significantly better than most of the organic and hybrid photodetectors reported so far. Based on this photodetector and an organic light-emitting diode (OLED), an organic optocoupler system with 1 MHz response frequency is successfully set up. Our results suggest that thickness-manipulated cosolvent strategy is a promising method in high-speed MAPbI3-based photodetectors.

The use of hybrid halide Perovskites is helping us get closer to our aim of completely selfsufficient structures in terms of energy production. Preparation of a device of photoactive material CH3NH3PbI3 {FTO (Fluorine-doped tin Oxide)/ CH3NH3PbI3/SpiroOMeTAD/Al} for the photovoltaic applications has been described in this article. Producing a homogeneous thin film through the use of lower temperature, processedsolution devices with one-step spin coating processes is an essential stage in the fabrication process. To generate the thin films on the FTO-substrate, the one-step spin coating approach was utilized for the deposition of the precursor solution, which consisted of methylammonium iodide and lead iodide in a molar ratio of 3:1. This technique was employed to prepare the thin films. The FESEM technique was utilized to carry out the investigation of the surface morphology of this thin layer. In addition, the essential parameters of this device, like barrier height, saturation current, current density, ideality factor, carrier mobility, resistance, carrier lifetime, and capacitance have been computed using current-voltage (I-V) characteristics and the impedance spectroscopy technique. A laser with a power of 20 milliwatts and a wavelength of 532 nanometers was used to light the gadget. The current conduction mechanism exhibits ohmic behavior at a low voltage, while at medium voltages, TFSCLC is the mechanism that regulates charge transportation. Despite the fact that TCSCLC is demonstrated at higher voltages. The TCSCLC model was used to conduct an investigation of the hole's mobility.

In this paper, a simple thermal evaporation deposition (TED) method is used to obtain high-quality bismuth triiodide (BiI3) films on FTO substrate using BiI3 powder as an evaporation source. The effects of annealing on the X-ray diffraction analysis and some optical parameters of BiI3 thin films were investigated. The results show that the annealing temperature on the BiI3 thin film has a great influence on the preferred orientation of the films. When the annealing temperature is 100 °C, for a deposition thickness of 400 nm, the thin films have high crystallinity and rhombohedral morphology. Scanning electron microscopy observation showed high special resolution of BiI3 thin films. UV–Vis transmission spectra have been recorded to determine the optical band-gap of BiI3 films prepared by TED. The obtained data reveal that the indirect optical band-gap of BiI3 thin films decreases from about 1.7 to 1.6 eV, while the Urbach tail width decreases from 484 to 236 meV, by annealing. We discuss the outstanding annealing effect on photo-physical characterizations of BiI3 thin film as a candidate solar cell absorber such as lead-free perovskite solar cells.
