TOPCon

Avaada Electro has started building a 5 GW integrated tunnel oxide passivated contact (TOPCon) solar cell and module plant and opened a 1.5 GW module factory near New Delhi, India.

Following the indictment of its chairman, Gautam Adani, in the United States over bribery allegations, questions are being asked about Adani Group’s ability to raise capital. With the charges related to solar, India’s PV industry has wider concerns. Adani Group refutes the allegations and says it is as robust as ever.

Climacy, a building integrated PV manufacturer, has launched a new semi-transparent 400 W glass-glass panel that is suitable for use in roofs or facades in residential, industrial and commercial buildings. When used as a roof or wall componentt, the 20% transparent panels reportedly allow more natural light into interior spaces than conventional PV designs.

Researchers at the University of New South Wales have used a 1 µm copper plating layer on the front silver grid of a TOPCon solar cell to create a protective barrier that reportedly reduces corrosion susceptibility. The cell showed significantly lower contaminant-induced degradation that unprotected reference devices.

The patent lawsuit, filed at Japan’s Tokyo District Court, is JinkoSolar’s second case of legal action against Longi this year, following a filing in China earlier this month.

The solar industry has dragged its heels on the issue of silver-dependence for cell metallization, but China’s Jiangsu Xianghuan Technology (JXTC) is moving into commercial production with a copper plating process that overcomes many of the challenges that have limited interest from cell manufacturers.

Three Gorges Group has opened bidding for 2.5 GW of 580 Wp and above n-type tunnel oxide passivated contact (TOPCon) solar modules. The 29 participating companies submitted bids averaging CNY 0.7012 ($0.096)/W, with the procurement framework running through mid-2025.

Waaree Energies says it has secured environmental product declaration (EPD) certification for its bifacial mono passivated emitter and rear cell (PERC) and tunnel oxide passivated contact (TOPCon) solar panels.

In five key trends, pv magazine looks back over a year that saw PV module prices fall lower than many thought possible, while demand was restrained by grid congestion, among other challenges. Energy storage has had a strong year and geopolitics is seeing solar and battery manufacturing enter new regions as competition drives technical innovation.

China Power Construction Corp. (PowerChina) says it has concluded the largest procurement tender in solar industry history, involving 51 GW of PV modules and 51 GW of inverters. The tender results, published on Nov. 13, set a new record for scale and industry involvement.
