Qcells, one of the world’s leading clean energy companies, and Lumet, producer of ultrafine-line metallization systems, announced that Qcells will become the world’s first PV solar company to deploy Lumet’s disruptive fine-line metallization technology for its PV solar cell lines. Qcells currently operates the largest solar module factory of its kind in the United States and has announced the largest investment in US solar history to build a complete and sustainable solar supply chain in America.

The explosive adoption of solar power around the world has been driven by society’s need to replace its dependence on fossil fuels with clean renewable energy. Today, solar is the fastest growing – and lowest cost – power source on the planet, a result of the industry’s relentless quest to enhance solar cell efficiency and lower production costs.

The single largest cost of solar cell production is the metallization step, in which conductive silver fingers (collectors) are screen-printed onto the cell’s surface. The industry has long sought to reduce finger width, in order to both decrease silver consumption (lower cost) and reduce light shading (increase efficiency).

However, screen printing technologies have now plateaued at finger widths of about 20 microns and are thus unable to deliver the efficiency and cost improvements sought by the industry.

Lumet fine-line metallization technology, capable of producing even sub-ten-micron finger widths, will enable PV solar cell producers to now attain both higher cell efficiency and lower cost. 

“After lengthy evaluation and testing, Qcells has decided to adopt Lumet metallization technology for its future PV solar cell lines,” stated Danielle Merfeld, EVP and global chief technology officer at Qcells. “We see tremendous potential in the Lumet metallization technology, which is a breakthrough on multiple fronts, setting records for finest lines, lowest cost, highest efficiency, highest speed and smallest footprint. Moreover, with Qcells’ commitment to expanding our USA-based manufacturing, the low CAPEX and high automation level of the Lumet systems are very attractive. For all those reasons, we are thrilled that Qcells will be the first to introduce this technology to the market and we look forward to taking further steps to deepening our strategic partnership with Lumet.”

Lumet founder and chairman, Benny Landa, added: “We are delighted to partner with Qcells and look forward to collaboratively bringing Lumet technology to the mass production PV solar market. Qcells has a rich history of pioneering and innovation. Not only is Qcells one of the world’s first solar pioneers, it was also the first to reach gigawatt-scale production – and to this day continues to be at the forefront of innovation, most recently with its introduction of LECO (Laser Enhanced Contact Optimization) technology. And now it is bringing the benefits of Lumet technology to the PV solar market – another first for Qcells! That’s very exciting news, both for us and for the PV solar industry!” 

Merfeld concluded: “Innovation and clean energy technology are going to be critical to cutting global emissions and developing low cost, accessible, reliable energy for communities around the world. That’s our mission. Today, in partnership with Lumet, we are taking an important step towards reaching that goal.”

Lumet offers a metallization technology for enhancing the efficiency and lowering the cost of PV solar cell production. By replacing silver pastes, screen printers and dryers, Lumet offers the industry’s simplest and lowest cost (CAPEX and OPEX) metallization technology. Moreover, at 10,000 cells per hour, Lumet is by far the industry’s highest speed PV metallization technology. With headquarters and R&D center in Israel, Lumet’s manufacturing operations are planned to be close to its customers in the United States and China.

Lumet is part of the Landa Group, one of Israel’s leading innovation enterprises. Other Landa Group companies include Landa Labs (the Group’s innovation center), Landa Digital Printing (digital commercial printing systems), Lusix (lab-grown diamonds) and NanoMetalix (digital printed electronics systems). 

In 2024, we are looking at full recovery and growth-led investment in Indian printing

Indian Printer and Publisher founded in 1979 is the oldest B2B trade publication in the multi-platform and multi-channel IPPGroup. It created the category of privately owned B2B print magazines in the country. And by its diversification in packaging, (Packaging South Asia), food processing and packaging (IndiFoodBev) and health and medical supply chain and packaging (HealthTekPak), and its community activities in training, research, and conferences (Ipp Services, Training and Research) the organization continues to create platforms that demonstrate the need for quality information, data, technology insights and events.

India is a large and tough terrain and while its book publishing and commercial printing industry have recovered and are increasingly embracing digital print, the Indian newspaper industry continues to recover its credibility and circulation. The signage industry is also recovering and new technologies and audiences such as digital 3D additive printing, digital textiles, and industrial printing are coming onto our pages. Diversification is a fact of life for our readers and like them, we will also have to adapt with agility to keep up with their business and technical information needs.

India is one of the fastest growing economies in nominal and real terms – in a region poised for the highest change in year to year expenditure in printing equipment and consumables. Our 2024 media kit is ready, and it is the right time to take stock – to emphasize your visibility and relevance to your customers and turn potential markets into conversations.
