BioSolar Announces Successful Scale Up Production Run of Biobased Plastic Film for Solar Cells

SANTA CLARITA, CA--(Marketwire - December 3, 2007) - BioSolar™, Inc. (OTCBB: BSRC), developer of a breakthrough technology to produce bioplastic materials from renewable plant sources that reduce the cost of photovoltaic solar cells, today announces that the company has successfully completed a scale up production run of high quality biobased plastic film intended for use as a backing sheet for photovoltaic cells.

In explaining the significance of this latest step toward commercialization of BioSolar's bioplastic materials, Dr. David Lee, CEO, said, "BioSolar has previously developed its biobased polymer which significantly improves the film's impact resistance and thermal performance. The film was successfully extruded at a narrow width. In order to check for possible scale up problems, we conducted an extrusion run at the full production width of 55 inches. There were essentially no scale up problems, and very high quality film was produced."

This is a key milestone in the development of the company's biobased backsheet product as the 55-inch-wide rolls of film exceed the industry maximum width requirement. Photovoltaic modules are expected to last for 20 years or more, and experimental modules made with this film are currently being tested to ensure that the film meets the longevity requirement. The test includes a 45-day temperature-humidity test as mandated by Underwriters Laboratories.

"As we continue to hit our targets in our research and development work, we are guided by input from our commercial strategic partners in the photovoltaic field," continued Dr. Lee. "This successful ramp-up to production scale film width moves us another step closer to commercial sales of our product."
