  • Smart optimization of rare-earth-based perovskite solar cells using machine learning approaches

  • Numerical Optimization of La0.5Ce0.5Fe0.9Zn0.1O3-Based Perovskite Solar Cell Using NiO as Hole Transport Layer and TiO2 as Electron Transport Layer for Enhanced Photovoltaic Performance

    Advanced Theory and Simulations, 2026
    Perovskite solar cells have become the most advanced among various solar‐energy conversion technologies owing to their highly efficient, flexible, and simple fabrication procedures. There is a growing focus on research toward lead‐free, eco‐friendly, and cheaper alternatives to conventional halide perovskites. In this work, La 0 . 5 Ce 0 . 5 Fe 0 . 9 Zn 0 . 1 O 3 (LCFZO), a stable and nontoxic oxide‐based perovskite, is explored as an absorber for single junction perovskite solar cells (PSCs). The bandgap of LCFZO 2.0 eV through Zn doping and stable structural and thermal behaviors make it a potential material for new generation solar cells. For the simulation‐based study, TiO 2 is used as the electron transport layer (ETL) due to conduction band alignment, low cost, and non‐toxicity, and NiO as the hole transport layer (HTL) for good hole extraction and chemical stability factors. A thorough investigation is carried out using SCAPS‐1D for numerical modeling, investigating the impact of absorber layer thickness, doping concentration, interface defect density, and series/shunt resistance on the photovoltaic performance. The presently simulated device offers an excellent efficiency up to 16.16% with LCFZO‐based PSC, making it a potential candidate for lead‐free, efficient, and stable photovoltaic devices. These results open doors to developing green and thermally stable perovskite solar cells in oxide perovskite frameworks.

  • Integrating Machine Learning With SCAPS-1D to Optimize Lead-Free LCCZO Perovskites for Sustainable Solar Energy Harvesting

    Energy Storage, 2025
    Perovskite solar cells (PSCs) have rapidly advanced as a next‐generation photovoltaic technology due to their high efficiency and flexible fabrication routes; however, the reliance on lead‐based absorbers raises concerns regarding toxicity and long‐term stability. This study introduces La 0.5 Ce 0.5 Co 0.9 Zn 0.1 O 3 (LCCZO), a double perovskite oxide, as a lead‐free, stable absorber candidate for eco‐friendly PSCs. First‐principles calculations validate its crystallographic stability and predict a direct bandgap of ~1.8 eV, suitable for efficient visible‐light absorption. Optical analysis reveals strong absorption and favorable dielectric properties, supporting low exciton binding and effective charge separation. Device simulations using SCAPS‐1D integrating TiO 2 and NiO as transport layers demonstrate optimal performance upon tuning absorber thickness, carrier density, and defect levels. A maximum power conversion efficiency (PCE) of 23.41% is achieved, with an open‐circuit voltage ( V oc ) of 1.42 V, short‐circuit current density ( J sc ) of 18.56 mA cm −2 , and fill factor (FF) of 88.92%. The device exhibits robust tolerance to bulk and interfacial defects, attributed to favorable band offsets and intrinsic defect chemistry. A machine learning model trained on simulated datasets accelerates performance prediction across parameter regimes, achieving ~82.5% accuracy and reducing computation time significantly. These results position LCCZO as a promising lead‐free absorber and highlight the synergy of computational design and machine learning for sustainable solar energy development.

  • Ac conductivity of transition metal oxide doped glassy nanocomposite systems: Temperature and frequency dependency

    Materials Research Express, 2018
    Transition metal oxide (TMO) doped different types of semiconducting glassy systems of the common terminology as 0.3V2O5–0.7 (0.05AmOn–0.95ZnO) for AmOn = MoO3, SeO2, Nd2O3, and CdO have been prepared by melt quenching route. The frequency and temperature dependent conductivity of all the as-quenched glass nanocomposite samples has been investigated over a wide temperature and frequency range. Conductivity, depending on temperature and frequency, is well established using Jonscher’s universal power law and Almond-West formalism. The values of DC conductivity (σdc), polaron hopping frequency (ωH), frequency exponent (n), and power law exponent (s) have been computed. The value of n indicates three-dimensional motions of charge carriers or polarons, which is the main reason for high-frequency dispersion in the ac conductivity. The estimated values of activation energy of ac conduction (Eac), free energy of polaron migration (EH) and activation energy of DC conductivity (Edc) are mainly owing to polaron transport with the energy level in the optical band gap. Ac conductivity and temperature dependent power-law exponent (s) of the as-prepared glassy samples containing MoO3 and Nd2O3 are dominated by non-overlapping small polaron tunneling (NSPT). Conversely, correlated barrier hopping (CBH) solely controls the ac conductivity and temperature dependent power-law exponent (s) of the glassy samples containing SeO2 and CdO. It is ascertained that mobile charge carrier concentration is independent of temperature and only 20%–25% of the total charge carriers (polarons) contribute to the ac conductivity of the presently studied glassy systems.

    Abstract Two series of semiconducting glass‐nanocomposites xAg 2 O – (1‐x) (0.1CdO – 0.9 MoO 3 ) and 0.3 Ag 2 O – 0.7 (yCdO – (1‐y) MoO 3 ) is prepared by melt‐quenching route. The formation of Ag 2 MoO 4, Ag 2 Mo 2 O 7 and Ag 6 Mo 10 O 33 nanocrystallites and CdO nanoparticles in glass‐nanocomposites is confirmed by the study of X‐ray diffraction (XRD) and field emission‐ scanning electron microscopic (FE‐SEM). The Fourier transform infrared (FT‐IR) spectra are being taken to find out stretching vibrations of monomeric tetrahedral orthomolybdate ion MoO 4 2− as well as stretching vibrations of Mo 2 O 7 2 – ions. Micro‐hardness of the as‐prepared samples is found to increase with load and shows a maximum for a particular load for different methods (Vicker's and Knoop's) and different compositions. The dc conductivity is described based on the polaron hopping approach to a wide temperature range. The variable range hopping Mott's (Greave's) model is employed to analyze the conductivity data at low (high) temperatures. The frequency exponent data show that ac conductivity is consistent with overlapping large polaron‐tunnelling (OLPT) model at all temperature.
