“…This is probably due to fast crystallization of the perovskite during spin-coating. 26,27) The SEM image shown in the inset of Fig. 1(b) for the two-step fabricated film still indicates the small fiber-like crystals but at a higher coverage than in the one-step spin-coated film.…”

“…Perovskite solar cells with a fiber-like structure have been reported with low power conversion efficiency (PCE) and large hysteresis. [26][27][28][29] Although the film morphology can still be improved, it is worth discussing the validity of the novel method for visualization of carrier motion in perovskite film. Then, XRD analysis was performed to characterize the crystalline properties of the fabricated film.…”

Direct observation of the carrier motion in electronic materials is helpful for understanding the phenomena of carrier transport and the operating mechanism of a device. Transient photoluminescence (PL) imaging is conducted to directly observe the carrier motion in organic–inorganic hybrid perovskite thin film. The PL intensity of perovskite films changes in accordance with the injection and extraction of charges during application of a voltage to a methylammonium lead iodide (CH3NH3PbI3) FET. The transient change in the PL intensity in the FET channel represents a successful visualization of the carrier transport. Lateral time-of-flight (TOF) measurement proves that the transient change in PL corresponds to the carrier transport. The hole mobility of the perovskite thin film could be evaluated as 2.3 × 10−2 cm2 V−1 s−1 by analyzing the transient PL motion. An increase in the PL intensity on application of a negative voltage to the source electrode indicates that intrinsic holes predominantly exist throughout the film.

“…At T < 163 K, it is in an orthorhombic phase, at 163 K < T < 327.3 K, it is in a tetragonal phase and beyond 327.3 K, it will begin to form a cubic phase [109]. Substantial changes occur at 60 • C, as it shifts from the tetragonal to the cubic phase, with better grain sizes, based on the XRD results from several research studies, as multiple new peaks are present compared to the tetragonal phase [110][111][112].…”

Hybrid Organic–Inorganic Perovskite Halide Materials for Photovoltaics towards Their Commercialization

et al. 2022

View full text Add to dashboard Cite

Hybrid organic–inorganic perovskite (HOIP) photovoltaics have emerged as a promising new technology for the next generation of photovoltaics since their first development 10 years ago, and show a high-power conversion efficiency (PCE) of about 29.3%. The power-conversion efficiency of these perovskite photovoltaics depends on the base materials used in their development, and methylammonium lead iodide is generally used as the main component. Perovskite materials have been further explored to increase their efficiency, as they are cheaper and easier to fabricate than silicon photovoltaics, which will lead to better commercialization. Even with these advantages, perovskite photovoltaics have a few drawbacks, such as their stability when in contact with heat and humidity, which pales in comparison to the 25-year stability of silicon, even with improvements are made when exploring new materials. To expand the benefits and address the drawbacks of perovskite photovoltaics, perovskite–silicon tandem photovoltaics have been suggested as a solution in the commercialization of perovskite photovoltaics. This tandem photovoltaic results in an increased PCE value by presenting a better total absorption wavelength for both perovskite and silicon photovoltaics. In this work, we summarized the advances in HOIP photovoltaics in the contact of new material developments, enhanced device fabrication, and innovative approaches to the commercialization of large-scale devices.

The Annealing Effect at Different Temperatures for Organic-Inorganic Perovskite Quantum Dots

et al. 2022

View full text Add to dashboard Cite

After the preparation of inorganic perovskite cesium lead iodide quantum dots (CsPbI3 QD) by ligand-assisted reprecipitation (LARP), CsPbI3 QD was added to the organic perovskite methylamine lead triiodide (CH3NH3PbI3; MAPbI3) to successfully form composite perovskite film. To obtain better perovskite quantum dot (PQD) crystal characteristics, this research used different annealing temperatures to discuss the crystallinity changes of perovskite quantum dots (PQD). Through X-ray diffraction (XRD) analysis, it was found that the preferred peak (110) of MAPbI3 had maximum peak intensity when the annealing temperature increased to 120 °C. Based on the measurement results of PQD’s Ultraviolet-Visible spectrum, it was shown that the maximum absorption area was obtained at the wavelength of 350 nm~750 nm at the annealing temperature 120 °C. From the scanning electron microscope (SEM) measurement, it was found that the grain size was the largest at the annealing temperature 120 °C, and the grain size was 60.2 nm. The best crystallization characteristics of PQD were obtained at the annealing temperature 120 °C.
