JA Solar has started production of its metal wrap-through (MWT) solar cells in China as a precursor to plans to be announced about its next-generation solar cell technology.

The tier 1 PV manufacturer previously joined forces with ECN in 2010 to commercialise MWT technology. Yingli Green has also been a long-term partner with ECN on MWT and other cell technologies.

JA Solar claimed that its MWT-based monocrystalline and multicrystalline cells had an average conversion efficiency of 19.6% and 18.1%, respectively. However, the cells have produced peak conversion efficiencies of 20.0% for monocrystalline and 18.6% for multicrystalline-based cells.

“MWT is at the core of the next generation of module technology, and represents a significant breakthrough in terms of power output and conversion efficiency,” said Mr. Yong Liu, CTO of JA Solar. “Mass production of MWT cells marks a significant milestone in JA Solar's ongoing technological leadership in the global solar industry.”

JA Solar had said in its most recent quarterly conference call that its average conversion efficiencies of its mainstream, non-MWT ‘CYPRESS’ monocrystalline and multicrystalline-based cells had achieved 19.15% and 17.5%, respectively in volume production.

However, in the conference call, Bill Chen, JA Solar’s vice president of strategic development said: “On the R&D side, we made a significant progress in technologies to enable and increase in conversion efficiency on at least 0.4%, making another important milestone in our roadmap to 20% efficiency. We expect to announce our next generation of solar cells in the second half of this year.”

JA Solar did not say what the expected megawatt capacity ramp of the MWT-based cells would be, though typically such cells can be produced on existing high-efficiency cell production lines in tandem with other advanced cells with the inclusion of specialist tool sets for MWT processing. Fully-dedicated MWT lines through to module encapsulation also exist.

As recently revealed in PV Tech’s exclusive review of the Top 10 manufacturer’s R&D spending analysis, JA Solar had restrained spending over the last five years when compared to its peers. The majority of spending had also been focused on wafer technology rather than cell technology. 

The collaboration with ECN and its technology partners from the equipment and materials sectors has proved to have been a low cost but successful path to bringing advanced cell technology to market within a relatively short period of time.

This year’s EV World Congress will hold a special role, not only as the first live EverythingEV event in over a year – a chance to renew your connections and re-engage with the EV sector face to face – but also as a chance to share insight and inspiration as world starts to look towards move on post COVID towards hitting ambitious decarbonisation goals in 2030 and beyond. As ever, we will be bringing world leading organisations, cities, and technology providers to the UK to inspire EV innovators, and delve into the challenges facing the sector as the UK looks to revolutionise road transport.

Utility-scale solar is evolving, shaped by higher power modules and demand for increasingly lower levelised cost of electricity (LCOE). Those trends are also changing project requirements elsewhere, with inverters capable of delivering high power density and power capacity in strong demand. In this webinar, FIMER will detail how its innovative high-power, multi-MPPT string inverter and modular conversion solution can both meet those demands and transform the utility-scale solar sector for the better.

The race is on but we need to sprint… With global climate talks fast approaching and time running out to prevent the most disastrous impacts of climate change, now is the time to act. The Summit will explore the opportunities that emerge from taking action on climate change and provide a clear pathway forward for governments, citizens and companies. Taking place just 10 days before the G20 meeting in Rome, on 30-31 of October, and in the lead up to the critical COP26 meeting in Glasgow from 31 October–12 November, this event will be instrumental in influencing ambitious global action.

The solar tracker market continues to mature at breakneck speed, with designs and component selections becoming ever-more complex in the pursuit of better project economics. But a more simplistic design could deliver a triple benefit of lower Capex, EPC and Opex costs. This webinar will set out the ideal single axis tracker design for utility-scale solar farms. The design leapfrogs from decades of experience, with a comprehensive understanding and attention to the three cost structures of Capex, EPC and Opx. Sun and Steel Solar has prototyped a single axis tracker designed to deliver up to US$0.03/W in real savings compared to existing single axis trackers on the market. That’s US$30 million for every gigawatt deployed.

The 10th edition of the famous Metallization and Interconnection Workshop, MIW2021, will take place in the Thor Central venue in Genk, Belgium, on Monday, November 15, and Tuesday, November 16, 2021 as a face-to-face meeting. We are longing for direct exchange of knowledge and ideas after a long time. Hopefully you can be part of it! But of course, the organizors will keep an eye on the evolution of the Covid pandemic. It will be assess carefully, whether the workshop can be held without major risks or excessive restrictions. We are looking forward to exciting talks, discussions and meetings and to welcoming you in Genk!
