BioSolar to Unveil Details of Company’s Breakthrough BioBacksheet(TM) Solar Technology at North America’s Most Prestigious Optics and Photonics Conference

BioSolar, Inc. (OTCBB:BSRC), developer of a breakthrough technology to produce bio-based materials from renewable plant sources that reduce the cost of photovoltaic solar cells, today reports that Chief Technology Officer Dr. Stanley Levy will deliver a key oral presentation at the SPIE Symposium on Solar Applications and Energy on August 12th in San Diego, California. Dr. Levy will detail the various scientific breakthroughs underlying the company's BioBacksheet(TM) product and its role in helping the photovoltaic industry drive the cost per kilowatt hour to lower levels.

Details regarding the development of BioSolar's Backsheet(TM), hailed by the daily news feature "Today's Green Minute" as a technology that "might revolutionize the industry," will be unveiled during SPIE Optics+Photonics, the largest and most technically prestigious optical sciences and technology meeting in North America. The Solar Energy + Applications track of the conference is dedicated to finding ways to move toward secure, affordable, and environmentally sustainable energy to meet the world's accelerating energy needs.

BioSolar's environmentally responsible BioBacksheet(TM) is made from renewable plant resources, rather than traditional and expensive petroleum-based components making it much more cost competitive than petroleum-based products. The resulting cost savings allows photovoltaic cell manufacturers to reduce the cost of their finished product, thereby reducing the cost per watt of solar electricity.

"We continue to receive positive feedback from an elite group of PV module manufacturers in regards to key durability and processing aspects of our BioBacksheet(TM)," said Dr. David Lee, CEO of BioSolar, confirming the progress toward full scale production of the company's flagship BioBacksheet(TM) product is on target. "This feedback provides key verification data points, and contributes to a growing sense of confidence in the company's progress toward full scale production."

As previously reported, BioSolar is transitioning to full-scale production of its BioBacksheet(TM) in a state-of-the-art manufacturing facility operated by its contract manufacturing partner, Rowland Technologies, Inc, a leading manufacturer of plastic film and sheet.
