Special Issue Information

Dear Colleagues,

Perovskite solar cells (PSCs) have emerged as a revolutionary photovoltaic technology due to their exceptional power conversion efficiency, low-cost fabrication, and tunable optoelectronic properties. This Special Issue explores recent advancements in perovskite materials, device architectures, scalable manufacturing techniques, and stability-enhancing strategies. We therefore welcome the submission of articles that highlight innovations in composition engineering, interfacial modifications, and computational modeling, alongside discussions regarding their commercialization and environmental impact. By bridging fundamental research and industrial applications, this Special Issue aims to accelerate the transition of PSCs from lab-scale breakthroughs to sustainable energy solutions. We invite researchers to share innovative findings that address efficiency, durability, and scalability, which are key to the future of perovskite photovoltaics.

Designing stable and multifunctional perovskite materials with tunable electronic and optical properties is crucial for advancing next-generation optoelectronic and high-temperature applications. In this study, the structural, electronic, optical, mechanical, and thermal properties of XYO3 (X = Nb, Ta; Y = Ag, Au) cubic perovskites were systematically investigated using density functional theory (DFT). Each compound crystallized into a cubic perovskite structure and was found to be both thermodynamically and dynamically stable. Hybrid functional (HSE06) calculations indicate semiconducting behavior with band gaps of 1.885 eV (NbAgO3), 1.298 eV (NbAuO3), 3.074 eV (TaAgO3), and 1.801 eV (TaAuO3). The density-of-state analysis reveals strong hybridization between the O-2p and Nb/Ta-d orbitals, which hints at mixed ionic/covalent bonding. Optical properties exhibit large absorption coefficients (about 106 cm−1) in the ultraviolet range and at lower reflectivity, especially of NbAgO3 and TaAgO3, indicating efficient light absorption. NbAgO3 and NbAuO3 possess moderate direct band gaps, making them suitable for optoelectronic and photovoltaic applications, whereas the wide bandgap of TaAgO3 is beneficial in ultraviolet optoelectronic devices. Mechanical analysis confirms the ductile nature of all compounds, with TaAuO3 exhibiting the highest ductility. Thermal analysis indicates that NbAgO3 and TaAgO3 exhibit higher lattice rigidity and thermal conductivity, but NbAuO3 and TaAuO3 are more anharmonic and have higher thermal expansion. Overall, these results demonstrate the multifunctional potential of XYO3 perovskites for applications in optoelectronics, photovoltaics, ultraviolet devices, flexible electronics, and high-temperature environments.

In this study, p-type NiOx and Cu-doped NiOx nanoparticles (NPs) were synthesized by a simple chemical precipitation method and used as hole transport layers (HTLs) for inverted perovskite solar cells (PSCs). The microstructural property, surface morphology, elemental composition, optical property, charge recombination, and surface topography of the NiOx and Cu-NiOx HTLs were comprehensively characterized. The results showed that the NiOx and Cu-NiOx NPs were uniformly coated on the substrates without pinholes or voids. Cu incorporation into NiOx did not change its crystalline nature and considerably improved its electrical conductivity. The Cu-NiOx HTLs exhibited superior photoluminescence quenching and the least lifetime decay, which indicated that Cu-NiOx exhibited higher charge transport than NiOx HTLs. The fabricated PSC performances were further analyzed using current density–voltage characteristics, external quantum efficiency, and electrochemical impedance spectroscopy. The PSCs with PEDOT:PSS, NiOx, and 2% Cu-NiOx HTLs exhibited power conversion efficiencies of 11.93%, 13.72%, and 15.54%, respectively. The 2% Cu-NiOx HTL-based device showed the best performance compared with the PEDOT:PSS- and NiOx-based devices. Academic Editors: Chunyang Zhang, Dou Zhang Full article
