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

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 9, Page 1125-1134, September 2026.
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.

Microstructure Analysis of Current‐Fired Contacts on TOPCon Layers

Solar RRL
We report on the analysis of the microstructure of a current‐fired contact formed by screen printing, drying, and sintering of a silver paste and subsequent laser‐enhanced contact optimization (LECO) for silicon solar cells with tunnel‐oxide passivated contacts (TOPCon) on the TOPCon side.

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

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 8, Page 1010-1022, August 2026.
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, Volume 34, Issue 8, Page 1037-1051, August 2026.
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 ...

Assessing the potential of TOPCon solar cells architecture using industrial n-type cast-mono silicon material

EPJ Photovoltaics
Cast-mono silicon material is interesting for its lower carbon footprint compared to Czochralski (Cz) monocrystalline silicon. However, solar cells fabricated using cast-mono (CM) silicon show lower performances.

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

Acta Ophthalmologica, Volume 104, Issue 5, Page e491-e502, August 2026.
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.
