“…Using a lowtemperature combustion technique, copper-doped NiOx (Cu:NiOx) achieved efficiencies of over 17.8%, outperforming the traditional sol-gel-derived hightemperature Cu:NiOx PCE of 15.5%. Thus, various elements such as Cu, Li, Mg, Cs, and Co can be doped into NiOx to improve conductivity and PSC efficiency by lowering interfacial resistance at the HTL/perovskite interface [11].…”

Glasses with the composition (11.5 − ×) CaO − 23.5Li2O − 65SiO2: × NiO mol. % (0 $$\le \times \leq$$ ≤ × ≤ 11.5) were synthesized by melt-quenching method. And a number of physical parameters have been established. The refractive index and energy gap were also used to estimate the metallization criterion, where these glasses have shown values fallings between high (insulators) and low (metals), indicating that they are semiconductors. The XRD pattern shows the amorphous nature of investigated glasses. A number of spectroscopic analyses of the studied glasses were performed, in relation to NiO content, including Fourier transform infrared (FTIR) and UV–Visible diffuse reflectance spectroscopy (DRS). Due to compositional changes, FTIR measurements have revealed structural changes in the glass network. Furthermore, with increasing NiO content, the asymmetrical bands of silicate units increase. The creation of Ni–O–Si bonds in the silicate matrix has been attributed to the introducing heavier Ni+2 as [NiO4]2− tetrahedral species in substitution of the lighter silicon ion in the [SiO4]4− network, but it could also operate as a network modifier in glass materials. The Ni2+ ion may have behaved as a network intermediary, causing more compact structure. The mechanism of charge transfer in the glass compositions under investigation is studied using broadband dielectric spectroscopy. For the first time, the relationship between the hopping time of free ions and dc conductivity is illustrated. All of the glasses under investigation have the same charge transport mechanism. The results suggest the semiconducting nature of these glasses.

“…With enhanced electrical and thermal properties, inorganic HTLs play a crucial role in achieving higher PCEs in PSCs, resulting in superior performance [45]. Overall, when considering factors like conductivity, stability, durability, thermal stability, compatibility, environmental resistance, performance and technology maturity, inorganic HTLs hold distinct advantages over organic HTLs in the realm of PSCs [46]. TiO 2 material has been found to be a suitable electron transport layer (ETL) for the PSC but it faces the issue of degradation owing to the presence of oxygen vacancies [47].…”

In recent decades, substantial advancements have been made in photovoltaic technologies, leading to impressive power conversion efficiencies (PCE) exceeding 25% in perovskite solar cells (PSCs). Tin-based perovskite materials, characterized by their low band gap (1.3 eV), exceptional optical absorption and high carrier mobility, have emerged as promising absorber layers in PSCs. Achieving high performance and stability in PSCs critically depends on the careful selection of suitable charge transport layers (CTLs). This research investigates the effects of five copper-based hole transport materials and two carbon-based electron transport materials in combination with methyl ammonium tin iodide (MASnI 3 ) through numerical modelling in SCAPS-1D. The carbon-based CTLs exhibit excellent thermal conductivity and mechanical strength, while the copper-based CTLs demonstrate high electrical conductivity. The study comprehensively analyses the influence of these CTLs on PSC performance, including band alignment, quantum efficiency, thickness, doping concentration, defects and thermal stability. Furthermore, a comparative analysis is conducted on PSC structures employing both p-i-n and n-i-p configurations. The highest-performing PSCs are observed in the inverted structures of CuSCN/MASnI 3 /C 60 and CuAlO 2 /MASnI 3 /C 60 , achieving PCE of 23.48% and 25.18%, respectively. Notably, the planar structures of Cu 2 O/MASnI 3 /C 60 and CuSbS 2 /MASnI 3 /C 60 also exhibit substantial PCE, reaching 20.67% and 20.70%, respectively.

“…On the other hand, the instability of perovskite solar cells is due to the hydroscopic properties of these organic cations, especially methylammonium. The stability of CH 3 NH 3 PbI 3 -based solar cells is mainly affected by moisture [ 12 ]. This is because water molecules form weak hydrogen bonds with perovskite cations, which disrupt the structural stability of the crystal [ 13 ].…”

Perovskite solar cells (PSCs) are a promising area of research among different new generations of photovoltaic technologies. Their manufacturing costs make them appealing in the PV industry compared to their alternatives. Although PSCs offer high efficiency in thin layers, they are still in the development phase. Hence, optimizing the thickness of each of their layers is a challenging research area. In this paper, we investigate the effect of the thickness of each layer on the photoelectric parameters of n-ZnO/p-CH3NH3PbI3/p-NiOx solar cell through various simulations. Using the Sol–Gel method, PSC structure can be formed in different thicknesses. Our aim is to identify a functional connection between those thicknesses and the optimum open-circuit voltage and short-circuit current. Simulation results show that the maximum efficiency is obtained using a perovskite layer thickness of 200 nm, an electronic transport layer (ETL) thickness of 60 nm, and a hole transport layer (HTL) thickness of 20 nm. Furthermore, the output power, fill factor, open-circuit voltage, and short-circuit current of this structure are 18.9 mW/cm2, 76.94%, 1.188 V, and 20.677 mA/cm2, respectively. The maximum open-circuit voltage achieved by a solar cell with perovskite, ETL and HTL layer thicknesses of (200 nm, 60 nm, and 60 nm) is 1.2 V. On the other hand, solar cells with the following thicknesses, 800 nm, 80 nm, and 40 nm, and 600 nm, 80 nm, and 80 nm, achieved a maximum short-circuit current density of 21.46 mA/cm2 and a fill factor of 83.35%. As a result, the maximum value of each of the photoelectric parameters is found in structures of different thicknesses. These encouraging results are another step further in the design and manufacturing journey of PSCs as a promising alternative to silicon PV.
