“…In solution processing, a mixture of both MX2 (M ¼ Pb, Sn; X ¼ Cl-, Br-, I-) and AX (A ¼ methylammonium MA); formamidinium, FA) is dissolved in an organic solvent and deposited through the spin coating to form a film (Figure 4), followed by annealing to produce the perovskite layer [15]. The post deposition annealing of the films at low temperature (T < 250°C) is sometimes used to increase phase purity and crystallinity [6]. Spin-coating allows deposition of hybrid perovskites on various substrates, containing glass, quartz, plastic, and silicon.…”

“…The solvent is selected such that can dissolve organic salt but cannot metal halide and the final organic-inorganic perovskite, toluene/2-propanol mixture is an appropriate solvent for the organic salt. The organic cations in solution intercalate into and react with metal halide on the substrate and form a crystalline film [6]. The dipping times are quite short: several seconds to minutes, depending on the system.…”

“…As the most fascinating new-generation photovoltaic materials, organic-inorganic perovskite due to their facile synthesis, low temperature deposition, and capability to make flexible devices has been considered as a vigorous component of the efficient, low-cost, lightweight and flexible Perovskite solar cells [3,4]. Perovskite solar cells (PSCs) have rapidly become the leading edge of third generation 3G photovoltaic technologies [5,6]. PSCs based on the organic inorganic perovskite materials have fascinated great consideration, with their power conversion efficiencies (PCEs) reaching 25.2% certified [7,8].…”

Organic-inorganic perovskite materials, due to the simultaneous possession of various properties like optical, electronic and magnetic beside with their structural tunability and good processability, has concerned the attention of researchers from the field of science and technology since long back. Recently, the emergence of efficient solar cells based on organic-inorganic perovskite absorbers promises to alter the fields of thin film, dye-sensitized and organic solar cells. Solution processed photovoltaics based on organic-inorganic perovskite absorbers CH3NH3PbI3 have attained efficiencies of over 25%. The increase in popularity and considerable enhancement in the efficiency of perovskites since their discovery in 2009 is determined by over 6000 publications in 2018. However, although there are broad development prospects for perovskite solar cells (PSCs), but the use of CH3NH3PbI3 results in lead toxicity and instability which limit their application. Therefore, the development of environmental-friendly, stable and efficient perovskite materials for future photovoltaic applications has long-term practical significance, which can eventually be commercialized.

“…In addition, exible PSCs of different colors can be fabricated effectively and advantageous to utilize large and wide wavelength ranges. The important parts of PSCs are transparent conductive oxides (FTO, ITO), electron transport layer (ETL), absorber layer (perovskite), hole transport layer (HTL), and the metal contact [5]. Miyasaka's group presented the rstever report and replaced dye-sensitized solar cells with perovskite (Ch 3 NH 3 PbI 3 ) used as liquid sensitizer and achieved power conversion e ciency (PCE) of 3.8% [6].…”

Among all the different methods to enhance the optical absorption of photovoltaic devices. The plasmonic effect is one the most prominent and effective ways to capture more incident light and also provide good carrier dynamic management. Here, we systematically introduce spherical gold nanoparticles (Au NPs) with different radii in the absorber layer of perovskite solar cells (PSCs). The overall enhanced optical absorption around 14.20% and 20.02% is achieved for incorporated monolayer and bilayer Au NPs, respectively, in the active layer compared to the pure perovskite layer. Moreover, we employ the metal (Au)-dielectric (TiO2 and SiO2) nanoparticles in the absorber layer. The optical absorption increases as the core-shell size decreases. The optical absorption elevates in both Au@TiO2 core-shell and Au@SiO2 core-shell 17.5% and 3.5%, respectively. These results support superior separation and transfer of charge in the existence of plasmonic NPs. In addition, this study presents a very sophisticated approach in the optical enhancement of PSCs and thus helps to boost the overall photovoltaic device performance.

“…The perovskite materials came to light as the most favorable and structured compound with minimal cost energy that finds extensive applications in opto-electronics as well as photonic devices [1,2]. A general perovskite structure has general composition formula in the form of ABX 3 , where A and B serve as cations in which basically A is a Group I or Group II element, B can be a transition metal and X serves as anion, for example halides (like chlorine, bromine, iodine) or oxides [3].…”

Density functional theory (DFT) investigation is performed to observe the opto-electronic properties of iridium and copper co-doped structure of Pristine SrTiO 3 (Cubic Perovskite). Results suggest that copper and iridium co-doped structure of SrTiO 3 has significant absorption in visible region of the spectrum, which is a result of red shift phenomenon in the wavelength range 400-750 nm observed in this structure. However, in individual copper and iridium structures the optical absorption is mainly in ultraviolet (UV) region which limits its use in light-based devices and applications. The shift in absorption from UV to visible region in the co-doped structure extracts the maximum utilization of solar light and finds wide range of optical applications like solar cells. Refractive index and dielectric constants were also calculated and their peak values were found to be in correlation with the peaks in absorption spectrum.
