Simultaneous derivation of carrier mobility through admittance spectroscopy on MBE grown GaAs/Al x Ga 1− x as based solar cell device 2026

Abstract Using admittance spectroscopy, the dispersive transport mobilities of electrons and holes were simultaneously obtained from the distinct carrier transit times ( τ t ) in the molecular beam epitaxy-grown GaAs/Al x Ga 1− x As heterojunction-based solar cell device. The negative capacitance effect was attributed…

End-of-Life Management of Photovoltaic Modules: Recycling, Second-Life Applications, and Disposal 2026

The rapid global expansion of photovoltaic (PV) systems, driven by rising energy demand, is expected to generate substantial module waste at end-of-life, with global PV waste projected to exceed 4 million tonnes by 2030, 50 million by 2040, and 200 million tonnes by 2050. Based on 102 publications identified through S…

CVD-grown nitrogen–boron co-doped graphene for enhanced performance of silicon-based solar cells 2026

Abstract Nitrogen and boron co-doped single-layer graphene was synthesized by the CVD method with NH 3 and B 2 H 6 as doping sources. The co-doping process aimed to enhance graphene’s film quality by introducing nitrogen and boron heteroatoms into the carbon lattice. Different NH 3 /B 2 H 6 flow ratios (5/5, 10/5, 15/…

Beyond Silver: Comparative Performance Analysis of Alternative Metallization in Silicon Solar Cells 2026

The reliance of photovoltaic industry on silver (Ag) for silicon solar cell metallization faces critical challenges due to Ag scarcity, cost volatility, and sustainability concerns. Here, we systematically compare advanced metallization strategies that minimize Ag usage while preserving cell performance. We evaluate d…

Manipulation of optical properties and band structure engineering of ultrathin nc-Si films due to the hydrogen dilution effect and annealing 2026

Abstract The optical properties and band structure of hydrogenated nanocrystalline silicon (nc-Si:H( x ) and nc-Si:H( x ) A , where the symbol x marks the hydrogen flow rate and the superscript indicates the annealed samples) in ultrathin films are investigated using UV-visible spectroscopic ellipsometry (SE) and ultr…

Computationally efficient gray-box modeling of photovoltaic parameters via higher-order degenerate Taylor polynomials and gradient boosting regression 2026

Recent advances in photovoltaic I-V modeling still face trade-offs among accuracy, computational efficiency, parameter estimation, and applicability. This study introduces third- and fourth order Enhanced Degenerate Current Taylor Series Expansion (EDCTSE) formulations derived from the Single Diode Model and validated…
