Working together, Dainippon Screen Manufacturing and Gifu University have produced a new technology that analyzes the characteristics of amorphous silicon films for thin-film silicon solar cell panels. The result from the research of the new technology is being used in spectroscopic ellipsometric film thickness measurement systems by Screen. Product creation is expected to be completed by this fall.

The thin-film silicon solar cells are said to  be able to allow for large-size cell panels to be manufactured with only a small amount of silicon used. Dainippon and Gifu look for the cells to be used in ground-mounted solar systems.

“Screen entered the solar cell industry in July 2008 as part of a plan to expand our business domains. We also began our collaborative research with Gifu University that November in an effort to strengthen the RE-8000 measurement system for thin film solar cells, the first product we released upon entering the market. We are extremely happy this research has now borne fruit in the form of a world-first technological discovery and we are just as pleased it is leading to the creation of a product equipped with a technology that represents a breakthrough for the thin-film solar cell industry. Screen hopes to grow the scale of its solar cell business to five billion yen by 2012 and we strongly believe this system will play a key role as a standard bearer for our business,” stated Katsumi Shimaji, corporate officer of Dainippon Screen.

Screen and Gifu have been working together since November 2008 researching the analysis of thin-film silicon solar cells. To date, the research has produced the ability to demonstrate an analysis method for amorphous silicon films to be used in the production of stable cell panels with minimal generation loss. This also allows for the digitization of information that is useful for a precise control of light-induced degradation.

Although the results of the research have been included into Screen’s spectroscopic ellipsometric film thickness measurement systems as a measurement function, work is still being conducting to commercialize the new technology into an accurate analysis of film properties, noncontact and nondestructive measurement of film thickness.

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!
