n-type TOPCon

Asier Ukar, the director of PI Berlin Spain, discusses the importance of addressing the risks associated with tunnel oxide passivated contact (TOPCon) tech early on, even though it outperforms (passivated emitter rear contact (PERC) when considering standard and tangible indicators.

The compact bifacial glass-glass modules are to be delivered from the third quarter. They are available in two different variants with an efficiency of 22.02 and 21.76%.

DMEGC Solar says its new tunnel oxide passivated contact (TOPCon) solar panels combine a double-glass design with half-cut n-type cell technology. It says the efficiency ratings range from 22.07% to 22.45%.

Trina Solar says its industrial tunnel-oxide passivated contact (i-TOPCon) solar cells, based on 210 mm wafers, have started rolling off the production line at its 8 GW factory in China. It will use the n-type cells to produce its new Vertex N modules, with power outputs ranging up to 605 W, and an efficiency rating of 22.4%.

The second-phase launch of Solarspace’s $1.47 billion manufacturing facility brings its total global production capacity of n-type solar cells to 35 GW.

China’s Hanersun has unveiled its HItouch 6N module series, which is based on n-type TOPCon tech, 210 mm wafers, and half-cut cells. The monofacial and bifacial modules feature power outputs ranging from 605 W to 695 W and efficiency ratings of 21.38% to 22.37%.

The device also showed an open-circuit voltage of 702 mV, a short-circuit current of 40 mA/cm2, and a fill factor of 79.7%. It has a large area of 239 cm².

On the first day of this year’s EU PVSEC conference, veteran solar researcher Pierre J Verlinden won the Becquerel Prize for Outstanding Merits in Photovoltaics. The award recognized more than 40 years as a leading PV researcher in academia and at leading companies including Sunpower and Trina Solar. Its recipient spoke to pv magazine about what is needed from solar to stave off catastrophic climate change.
