TOPCon solar cells

, 2022
13931399The authors present their work on laser-enhanced contact optimization (LECO) on iTOPCon solar cells. LECO improves the metal-semi-conductor contact resistivity ρc on the boron emitter and the n-TOPCon side from an underfired (thermal budget too ...

Simulation Insights Into Enhanced Emitter Contact Passivation via LECO on Industrial TOPCon Solar Cells

Progress in Photovoltaics: Research and Applications, EarlyView.
Numerical simulations were employed to boost industrial TOPCon cells from 25.5% to 26.07% by suppressing J0e,metal,eff without compromising ρc with a dual optimization strategy: (1) engineering the selective emitter sheet resistance (Rsh_SE) to 117 Ω/□ and (2) reducing the LECO‐induced partial metal contact ratio (fpmc) to 1%.

Grid Optimization of Tunnel Oxide Passivated Back Contact Silicon Solar Cells

Progress in Photovoltaics: Research and Applications, EarlyView.
The grid pattern design of tunnel oxide passivated back contact silicon solar cells were optimized via device simulation and the estimated cell efficiency was correlated to the required Ag paste consumption. The absolute efficiency gain of zero‐busbar design over pad‐based contact design is more than 0.1%, with increasing advantage when the Ag paste ...

Ultra‐Thin Bipoly Solar Cells With Front Selective n$$ n $$‐Type TOPCon and Rear Blanket p$$ p $$‐Type TOPCon Layers

Progress in Photovoltaics: Research and Applications, EarlyView.
Large area crystalline silicon solar cells fabricated on ultra‐thin (80 μ$$ \upmu $$m) Si wafer featuring polysilicon‐based passivating contacts on both sides can further increase the energy output per unit weight. In this work, the large area, screen‐printed solar cells with high temperature fire‐through contacts, yielded an exceptional efficiency‐to ...

Enabling EVA for TOPCon: How Glass Frit Composition Governs Resistance to Acetic Acid–Induced Corrosion

Progress in Photovoltaics: Research and Applications, EarlyView.
This work reveals that glass frit chemistry governs acetic‐acid‐induced corrosion and damp‐heat stability in LAF‐processed TOPCon modules. Compared with a Pb/B‐rich frit, a Ba/Zn‐modified frit preserves the Ag–Si interface, suppresses contact‐resistance increase and improves module reliability.

Prognostic factors of optical coherence tomography angiography in intermediate and advanced primary open‐angle glaucoma: A systematic review and meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract Conventional optical coherence tomography (OCT) has a floor effect in patients with severe visual field loss, such as seen in advanced primary open‐angle glaucoma (POAG). OCT angiography (OCTA) does not suffer from such a floor effect. However, which OCTA parameters are most useful for monitoring longitudinal progression is unclear.
