USA: Magnolia Solar Corp. announced that its wholly owned subsidiary, Magnolia Solar Inc. has demonstrated a flexible CIGS solar cell with an efficiency of 13 percent, rivaling the average efficiency of current PV technologies and proving that flexible thin film solar cells are potentially a viable solution for various energy needs.
The flexible CIGS solar cell, made using thin, flexible stainless steel and titanium substrates, was developed and produced by the U.S. Photovoltaic Manufacturing Consortium (PVMC) on behalf of Magnolia Solar at the College of Nanoscale Science and Engineering's (CNSE) Solar Energy Development Center (SEDC) located in Halfmoon, New York.
This flexible solar cell demonstration is the result of the successful and continuing collaborative research effort between Magnolia Solar, CNSE, and PVMC, and is supported by the New York State Energy Research and Development Authority (NYSERDA).
To increase the adoption of game-changing clean energy solutions, Magnolia Solar intends to continue to work with CNSE to further develop high-efficiency flexible solar cells for defense and commercial applications, making use of their significant advantages over inflexible solar cells that are made using crystalline silicon and thin film solar cells on glass.
Magnolia Solar has filed multiple patents to protect its intellectual property, and the company continues to add to its patent portfolio. Magnolia is also making progress with further improvements to the CIGS solar cells and nanostructured AR coating technology for solar cell applications. This nanostructured antireflection coating uses oblique angle nanostructure growth, thereby enhancing energy absorption and minimizing reflection loss.
