Company Expects New Bio-Based Product to Be Well Received in Growing Solar Cell Market

SANTA CLARITA, CA--(MARKET WIRE)--Mar 10, 2008 -- BioSolar(TM), Inc. (OTC BB: BSRC.OB), developer of a breakthrough technology to produce bio-based materials from renewable plant sources that reduce the cost of photovoltaic solar cells, today reports the successful development of its first generation commercial product, a backsheet component for photovoltaic cells. The new bio-based product, christened the "BioBacksheet" is the successful result of the company's technology development program.

As previously reported by BioSolar, record high oil prices and the emergence of a renewed emphasis on environmental awareness coalesced to create an inflection point for the development of a new market segment in the multi-billion dollar photovoltaic industry. The company's management believes that this market phenomenon provides a unique competitive advantage for BioSolar's bio-based solar cell components.

In rapid succession, the company reported the successful scale-up production run of bio-based films (Dec 07), the culmination of a rigorous testing protocol which moved the company another step closer to UL certification (Jan 08), and most recently the company announced the expansion of its R&D facilities and the establishment of its physical plant (Feb 08).

"As a result of our rigorous product development cycle, we now have the relevant data and positive test results that enable us to commit the company to full production of this particular product," said Dr. David Lee, BioSolar's CEO. "The decision is based on the product's cost benefits as well as durability -- selected from proven configurations as a result of BioSolar's own testing protocol as reported in January of this year."

Elaborating on the specific characteristics of the final product, Dr. Stan Levy, the company's CTO, explained that "this backsheet material is a composite utilizing two different sustainable resources, each of which has the necessary Underwriter's Laboratories Relative Thermal Index (UL RTI) to be accepted by the major photovoltaic manufacturers."

This is a key element to rapid attainment of market share, because it is much easier for a photovoltaic module manufacturer to obtain a re-certification of their UL approved module when they replace a component with a material that already has the required UL RTI. "This was a key directive in our product development strategy," noted the company's CEO.

"We expect that backsheet samples will be made available in commercial quantity to crystalline silicon photovoltaic module manufacturers in mid 2008, with full production runs to be scheduled based on the initial market response," said Dr. Lee. "Availability of these samples at quantity means that mainstream photovoltaic module manufacturers now can undertake their own UL recertification process utilizing BioSolar's BioBacksheet product."
