Chinese solar manufacturer JinkoSolar has announced a back-contact TOPCon solar cell achieving 28% efficiency, combining the technology with amorphous silicon heterojunction passivation. The result, reported by pv magazine, marks a notable efficiency milestone for the widely deployed TOPCon platform and signals continued competition among cell makers to push conversion efficiencies higher as the global solar market grows.
- 3Trina Solar researchers propose new classification of UV degradation in TOPCon cellsโผTrina Solar researchers propose new classification of ultraviolet-induced degradation in TOPCon solar cells
Researchers at Trina Solar have put forward a new classification system for ultraviolet-induced degradation in TOPCon solar cells. The proposal, reported by pv magazine Global, aims to standardise how the industry identifies and measures UV-related performance loss in this widely deployed cell technology. The work could inform testing standards and reliability assessments as TOPCon becomes the dominant solar cell type worldwide.
- 4Trina Solar Proposes New Classification for UV Degradation in TOPCon CellsโTrina Solar Proposes Reversible and Irreversible Classification for UV-Induced Degradation in TOPCon Cells
Trina Solar has proposed a new classification system that separates ultraviolet-induced degradation in TOPCon solar cells into reversible and irreversible forms. The company argues this distinction matters for how module performance loss is measured and predicted over a solar project's lifetime. The proposal is drawing attention in the solar industry as TOPCon technology becomes the dominant cell architecture and buyers seek clearer warranty and durability standards.
- 5UV down-shifting layers could lift TOPCon solar output over 4%โUV down-shifting layers could boost TOPCon solar module energy yield by over 4%
Researchers report that adding UV down-shifting layers to TOPCon solar modules could raise their energy yield by more than 4%. The layers convert ultraviolet light into wavelengths the cells use more efficiently, reducing losses in the blue part of the spectrum. If validated at scale, the finding could improve the economics of TOPCon technology, which is fast becoming the dominant solar cell design worldwide.
- 6First Solar sues JA Solar over TOPCon patentsโผFirst Solar sues JA Solar and American Panel Solutions over TOPCon patents
First Solar has filed a lawsuit against JA Solar and American Panel Solutions, alleging infringement of its TOPCon solar cell patents. The case escalates a widening intellectual property dispute in the solar industry, as manufacturers race to commercialise TOPCon technology, which has become the dominant cell architecture in mainstream photovoltaic modules.
- 7First Solar sues JA Solar over TOPCon patent infringementโผFirst Solar files TOPCon patent infringement lawsuit against JA Solar, American Panel Solutions
First Solar has filed a patent infringement lawsuit against JA Solar and American Panel Solutions, alleging unauthorized use of its TOPCon solar cell technology. The suit escalates an ongoing patent battle in the solar industry, where First Solar has previously pursued legal action against Chinese panel makers. The case could affect technology licensing and supply chains across the global solar market.
- 8Topcon launches Oku Digital Health to connect eye care and primary careโOku Digital Health launches from Topcon to link eye care, primary care
Topcon has launched Oku Digital Health, a new venture aimed at linking eye care with primary care. The company says the initiative is designed to bridge ophthalmology and general medicine so that eye health data and diagnostics can support broader patient care. Coverage so far has come from ophthalmology trade press, with industry watchers noting the growing push to integrate specialty eye care into routine primary care settings.
