(Yicai Global) June 16 -- Chinese photovoltaic firms have signed lucrative deals with global customers at this year’s Intersolar Europe expo in Munich, Germany, which ends today.

“I see far more potential than pressure,” a Chinese exhibitor told Yicai Global.

Xi’an-based Longi Green Energy Technology, a large solar panel maker, inked a framework supply agreement with Austria’s Energy3000 during the exhibition, with a plan to provide modules for several projects in Europe and other regions for three years.

JA Solar Technology penned two cooperation deals with Solatio, one of the largest developers of solar power plants in Brazil. The Hebei province-based renewable energy giant will supply 1.2 gigawatts of solar panels to power plants in Brazil, and 4 GW of panels to Solatio’s seven Brazilian projects over the next few years.

Intersolar Europe is the world’s largest solar energy trade fair. This year it had an exhibition area of over 130,000 square meters and nearly 2,000 exhibitors, more than in previous years.

Shanghai-based Aiko Solar Energy signed a 1.3 GW panel supply deal with Germany’s Memodo, focusing on the high-end distributed market in Europe.

N-type solar products were a highlight of this year’s expo, as they were at the International Photovoltaic Power Generation and Smart Energy Conference and Exhibition in Shanghai in late May. Compared to mainstream P-type products, N-type products have higher cell efficiency but a more complex manufacturing process.

Both JA Solar and Aiko Solar showcased new N-type products in Munich.

Longi announced that it has achieved 33.5 percent conversion efficiency for crystalline silicon-perovskite-based tandem solar cells on commercial-grade textured Czochralski silicon wafers, up from the 31.8 percent it claimed at the Shanghai expo last month.

“With a basic 20 percent conversion efficiency, every 1 percentage point rise in conversion efficiency can save more than 5 percent of costs for downstream power plants,” Longi founder Li Zhenguo said. “So even an improvement of only 0.01 percentage point is of great significance.”
