China Education Equipment Purchasing Network News: According to recent news from the Ministry of Science and Technology, the conversion efficiency of 1.1 square centimeters of organic thin-film solar cells developed by Heliatek in Germany has reached 9.8%, which has created new world record. This is also the company's third consecutive world record in the field of organic photovoltaic (OPV) technology. The company has optimized the overall absorption efficiency of the battery through the targeted selection of solar cell etching materials. In addition, by improving the coating deposition process, the battery's current flux and filled particle density can be further improved.

The chief technology officer of Heliatek said: "Heliatek is the only company in the world that focuses on low-temperature deposition of small molecule technology, which has been widely used in the organic LED market. Heliatek has developed molecular materials for absorbing light energy into electrical energy. New record It also proves that our research direction is correct. At present, the conversion efficiency of Heliatek's organic solar cells has reached the conversion level of traditional amorphous silicon cells. "

In 2010, Heliatek had set a world record of 8.3% conversion efficiency, and this time it was increased by 1.5%. Heliatek's research and development work was funded by the "Organic Photovoltaic Research Initiative" program implemented by the German Federal Ministry of Education and Research (BMBF).
