“…Additionally, there is a material which just likes soil which was decreasing in size as shown in Figures 2(a) – 2(c) with increasing bath temperature from 20°C to 85°C that shield over cadmium sulphide thin films in some amounts of the apparent. The impact of temperature on the surface morphology of nano-synthesized lead selenide films was observed; this is in good agreement with a reported study [ 14 ].…”

The influence of bath temperature on nano-manufactured PbSe (lead selenide) films was successfully generated by utilizing CBD on the acid solution’s metal surface tool. Pb (NO3)2 was employed as a lead ion source as a precursor, while Na2O4Se was used as a selenide ion source. The XRD characterization revealed that the prepared samples are the property of crystalline structure (111), (101), (100), and (110) Miller indices. The scanning electron microscope indicated that the particles have a rock-like shape. There was a decrement of energy bandgap that is from 2.4 eV to 1.2 eV with increasing temperature 20°C–85°C. Thin films prepared at 85°C revealed the best polycrystal structure as well as homogeneously dispersed on the substrate at superior particle scales. The photoluminescence spectrophotometer witnessed that as the temperature of the solution bath increases from 20°C to 85°C, the average strength of PL emission of the film decreases. The maximum photoluminescence strength predominantly exists at high temperatures because of self-trapped exciton recombination, formed from O2 vacancy and particle size what we call defect centres, for the deposited thin films at 45°C and 85°C. Therefore, the finest solution temperature is 85°C.

“…(Py) 2 film. This porous structure facilitates the diffusion of organic molecules like FAI into the PbI 2 film, resulting in the formation of high-quality perovskite crystals [54]. Consequently, after pyridine vapor treatment, the grain size of the perovskite film is twice that of the reference sample, leading to a significant improvement in film quality.…”

Perovskite solar cells have garnered significant attention as the next-generation photovoltaic devices. After more than a decade of dedicated research, commercializing these cells is now on the horizon. One of the primary focuses for developers aiming at large-scale industrial production is cost reduction. To achieve cost savings in perovskite solar cell manufacturing, researchers have successfully devised cost-effective room-temperature perovskite solar cells for fabricating perovskite films at room-temperature. Additionally, they have developed full room-temperature perovskite solar cells, where the entire solar cell is fabricated at room temperature. These cells excel in terms of their straightforward processing, low energy consumption, and continuous production capability, rendering them highly suitable for industrial applications. This article is intended to provide an overview of the latest advancements in room-temperature perovskite solar cell research. It will summarize commonly utilized methods for their fabrication, delve into the significant implications of full room-temperature perovskite solar cells for the commercialization of perovskite solar technology, and conclude by outlining various production techniques for room-temperature perovskite films. Furthermore, this article will offer insights into the future development directions of room-temperature perovskite solar cells and full room-temperature perovskite solar cells.

“…The film growth process of the halide perovskite materials in the presence of the DMF solvent is proposed; the advantage of DMF for the crystallization is elucidated via the comparison with the dimethylacetamide (Figure 2H), 119 while the perovskite precursors dissolved in DMF containing p‐type dopant is viable to improve the device performance (Figure 2I). 120 (3) More types of solvents are available beyond DMSO and DMF, such as isopropanol 121‐123 and trifluoroethanol 124‐126 . Replacing DMSO with N‐methyl‐2‐pyrrolidone (NMP, C5H9NO) leads to the formation of a stable intermediate adduct that is ascribed to the stronger interaction between NMP with NH 2 CH=NH 2 I (FA) (Figure 2J), 127 while the complex molecule‐mediated film growth process is elucidated when FAI, MAI and PbI 2 (DMSO) x are considered in DMSO and diethyl ether 128 .…”

The molecular approach is an effective way to improve the optoelectronic performance and stability of perovskite solar cells. In this manuscript, we review the progress and design principles of the molecular compounds for perovskite solar cells. The molecular design strategies that consider the A-site cations, additive molecules, solvent molecules, and surface adsorbates are explained, followed by a discussion on the molecular design at different perovskite-related interfaces, including the perovskite/perovskite interface, the electron transporting layer/perovskite interface, and the hole transporting layer/perovskite interface. Subsequently, the molecular impacts on the charge transfer directions at the perovskite surface and the molecular engineering on the molecular-scale halide perovskites are elucidated. The machine learning methods are emphasized to globally optimize the molecular layers for the perovskite solar cells from the complicated multidimensional virtual design space. Last but not least, the molecular design protocols are summarized and the suggestions for the future research directions on the molecular design for the halide perovskite materials are provided. This manuscript highlights the effectiveness of the molecular design strategies to improve the optoelectronic performance and stabilities of the perovskite solar cells.
