World`s First Bio-based Solar Panel Backsheet Now Qualifies for Commercial

Production after Completion of Research and Development Phase
SANTA CLARITA, Calif.--(Business Wire)--
BioSolar (OTCBB: BSRC), developer of a breakthrough technology to produce
bio-based materials from renewable plant sources that reduce the cost of
photovoltaic (PV) solar cells, announced today that the research and development
phase for the company`s proprietary BioBacksheet-C has been completed. Now
qualified for production, the BioBacksheet-C, designed for traditional silicon
(c-Si) photovoltaic solar panels, will be the company`s first product to become
available commercially.

"Designed specifically for cost-sensitive, economical PV solar cell modules, we
expect the BioBacksheetTM-C to be instrumental in driving down the cost per watt
of solar power," said Dr. David Lee, President and Chief Executive Officer of
BioSolar. "An initial full production run was recently completed at one of our
manufacturing partners and samples will be available for all interested PV
module manufacturers shortly."

BioSolar is working to make solar power "greener" and more affordable by
developing natural, non-toxic alternatives to the petroleum-based film in use by
most silicon-based solar module manufacturers today. Its proprietary line of
BioBacksheets, made from renewable plant sources rather than petroleum, meets or
exceeds the characteristics of various testing and performance standards for the
PV industry and are expected to cost significantly less than current
petroleum-based films.

"BioBacksheet-C meets or exceeds all industry standard qualifications," said Dr.
Stanley B. Levy, Chief Technology Officer of BioSolar. "They have been tested
and passed some of the most rigorous tests of UL 1703, the Underwriters
Laboratories PV certification standard, including the damp heat test, where the
module is exposed to 85 degrees C and 85% RH for 100 hours and the wet Hipot
test, which is a measure of short circuit resistance after the module has been
submerged in water."

"BioBacksheet-C is a two component system that is highly water resistant and
contains high dielectric strength material combined with cellulosic film," added
Dr. Lee. "The substrate is a cellulosic material coated with a proprietary
material to reduce the water vapor transmission rate and to increase abrasion
resistance."

About BioSolar, Inc.

BioSolar, Inc. has developed a breakthrough technology to produce bio-based
