How Wet Chemistry Can Increase PV Production Yields and Improve Efficiency

Lotus Systems, a leading manufacturer in the use of chemical substances to optimize the production process for photovoltaics, semiconductors, and MEMS, will be participating for the first time in the Intersolar trade show in San Francisco, Moscone West Convention Center, 2nd Level, booth no. 8445 from July 14-16, 2009. The Lotus experts will be coming all the way from Germany's Black Forest region to demonstrate how wet chemistry can increase PV production yields, accelerate processes, and improve efficiency - whether for crystalline solar cells or thin-film technology. Our experts will be available for individual consultation at the Lotus booth. Visit to find out more about wet chemistry.

“USA, here we come!” says CEO Joachim Mink. “We want the American photovoltaic market to benefit from the technologies that have been successful in Europe.” These technologies include everything from spray cleaners to wet process applications like texturization to thin-film module processing, including electroless photovoltaic coating. “Our wealth of experience with semiconductors and MEMS is what makes us so special. As early as 1989, we were using this experience to optimize photovoltaic processes,” Mink says. He is confident that “our expertise will now allow all PV manufacturers to cut costs and increase efficiency.”

At the Lotus Systems booth, representatives will provide information about a new wafer drying system. Current methods involve drying cells with circulating air after the last rinse step. This requires a great deal of energy and causes breakage. The German inventors at Lotus are using new techniques here.

Lotus Systems sees itself as a consultant: Lotus engineers have taken their comprehensive experience in the semiconductor and MEMS industries and adapted it to photovoltaics. They provide manufacturers with individual advice to help them optimize PV production.
