Solar Frontier and IBM have agreed to collaborate on the joint development of copper-zinc-tin-sulfur thin-film photovoltaics technology. IBM, which said in February that it had achieved 9.6% conversion efficiencies on champion cells made with the earth-abundant materials, also recently announced that it has partnered with DelSolar to work on CZTS.
 
The collaboration between Solar Frontier and IBM pairs the Japan-based CIS thin-film company's development and manufacturing expertise with Big Blue's strong R&D capabilities. The CZTS joint development program will mainly take place at IBM’s Thomas J. Watson Research Center in Yorktown Heights, NY.

CZTS-based technology uses materials that avoid heavy metals and are readily available at a lower cost. Through the utilization of these materials, the project's goal is the creation of next-generation photovoltaic technology that lowers the cost of solar-produced electricity, enabling the renewable energy to become an everyday alternative to carbon-based sources.

“Solar Frontier’s extensive experience in the research and development of CIS thin-film photovoltaic technologies has delivered numerous conversion efficiency breakthroughs that have resulted in world-class records,” said CTO Satoru Kuriyagawa. “We are interested in exploring CZTS for its evolutionary compatibility with our CIS thin-film technology. The goals of the project correspond with Solar Frontier’s mission to combine both economical and ecological solar energy solutions.”

“Solar Frontier is one of the world’s leading experts in CIS-based thin-film solar panels, and we look forward to working with them.” said T.C. Chen, VP of science and technology at IBM Research.
“Adding Solar Frontier’s deep expertise in thin-film-based solar device technology to this project will strengthen the collaborative effort we began in this area with Tokyo Ohka Kogyo for developing chemistry and tooling expertise; and more recently adding DelSolar’s solar module and manufacturing expertise. This team will significantly increase our ability to create CZTS photovoltaic technology that achieves sustainable grid parity.”

Further details about the personnel deployment, financial arrangements, or length of the agreement have not been disclosed.

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!
