China module prices steady amid bearish outlook
In a new weekly update for pv magazine, OPIS, a Dow Jones company, reports that TOPCon modules from China held steady at $0.083/W. Meanwhile, the spot price for U.S. TOPcon modules over 600 W was assessed this week at $0.263/W.
From TOPCon dominance to the rise of back-contact solar modules
Having invested heavily in TOPCon, solar manufacturers in India are beginning to explore hybrid solutions such as BC-TOPCon as a bridge between TOPCon and back-contact (BC) technologies. These hybrid models could ease the transition to BC by enabling manufacturers to leverage existing infrastructure while incorporating more efficient designs.
Researchers warn of ‘hidden contaminants’ that could increase TOPCon, HJT solar module humidity-induced degradation
Australian researchers have identified five contaminants that could increase damp heat-induced degradation in TOPCon and heterojunction cells and modules. Their analysis has shown these contaminants could originate from improper handling during cell or module processing.
Beyond the hype: Why PERC still powers a stronger solar future
New doesn’t always mean better: Passivated emitter and rear contact solar cells have earned their place through real-world reliability and cost-effective manufacturability.
Solar technologies at crossroads
Experts set to speak at the NetZero Milan Expo-Summit 2025 on May 15 have told pv magazine that tunnel oxide passivated contact (TOPCon) will remain the dominant cell technology in the near term due to ongoing advancements, despite rising competition from back-contact and heterojunction technologies.
China module prices bearish, U.S. prices rise on tariff policies
In a new weekly update for pv magazine, OPIS, a Dow Jones company, reports that TOPCon modules from China held steady at between $0.085-0.090/W. It also reveals that Europe prices for TOPCon modules of over 450 W rose by 0.96%, assessed at €0.105/W.
Jolywood’s laser-assisted firing process increases TOPCon solar cell efficiency by 0.6%, says UNSW research
New research from the University of New South Wales have found that the Special Injected Metallization (JSIM) technique developed by Chinese manufacturer Jolywood can considerably increase TOPCon solar cell efficiency. The scientists described precisely how laser-assisted firing enhances cell performance, reportedly filling critical gaps in industrial TOPCon cell optimization.
DAS Solar plans 3 GW solar module factory in France
Chinese manufacturer Das Solar says it will open its first European PV panel assembly plant in Mandeure, eastern France, by the end of 2025.
Solex 2 GW TOPCon cell line to come online by early 2027
Gujarat-based Solex Energy has initiated the work on its state-of-the-art 2 GW n-type TOPCon solar cell manufacturing facility, with operations slated to begin in early 2027.
Current UV tests overestimate TOPCon solar module degradation
Fraunhofer Institute for Solar Energy Systems ISE (Fraunhofer ISE) has found that current UV testing methods overestimate degradation in tunnel oxide passivated contact (TOPCon) solar modules, as dark storage after UV exposure causes temporary efficiency losses that largely reverse under sunlight.
