BioSolar's Successful Completion of Rigorous Testing Protocol Is an Important Step Forward Toward UL Certification

SANTA CLARITA, CA--(Marketwire - January 17, 2008) - 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 the company's backsheet material has passed the rigorous Damp Heat Test, moving the materials one step closer to Underwriters Laboratories (UL) certification.

As specified in UL testing protocol 1703, the Damp Heat Test ascertains the product's ability to withstand years of exposure in an outdoor environment without breaking down. This test subjects the material to 1000 hours at 85 degrees and 85% humidity. The test was successfully completed on January 16, 2008. UL 1703 is a comprehensive series of tests for photovoltaic modules. These tests are time consuming, and all requirements must be satisfied.

Dr. Stanley Levy, the company's Chief Technology Officer, said, "We are pleased to report that our backsheet materials have passed this test, which is one of the most severe tests included in the UL 1703 protocol. We will analyze these results to focus in on the most promising candidate for final production certification."

As detailed previously, SBM Solar of Concord, NC, a strategic partner of BioSolar, is in the final process of obtaining UL certification for their all polymer packaged PV module. Upon receiving their UL certification, SBM will submit additional modules to Underwriters Laboratories for UL approval, changing their standard backsheet material to BioSolar's bio-based backsheet. By utilizing a complete photovoltaic module that has already received UL approval, and only replacing one component (the backsheet material), the company expects to "fast track" the approvals process.

While emphasizing the grueling nature of the UL approval process, Dr. David Lee, BioSolar's President and Chief Executive Officer, provided additional insight into BioSolar's approach to the company's "fast track" process saying, "UL approval is an extremely demanding process. It can take years and hundreds of thousands of dollars to obtain UL approval for a photovoltaic module. Our 'fast track' process is expected to dramatically shorten the time it takes for the first solar module maker, our partner SBM Solar, to obtain UL approval with our backsheet."

"We're talking months not years," said Dr. Lee. "We expect that this will place competitive pressures on other photovoltaic manufacturers to accelerate their own UL approval process incorporating BioSolar's backsheet."
