Market Wire, April, 2008

BioSolar(TM), 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 announced that the company has shipped its BioBacksheet(TM) samples to a select group of manufacturers for their evaluation in several regions of the country. In an era of record high oil prices, the company's new bio-based product provides a cost effective alternative to petroleum-based backsheets currently in use, and has been actively sought by manufacturers as a component of their finished solar cells.

"This is a very exciting first step to market," said Dr. David Lee, BioSolar's CEO. "It has been our company's mission to deliver an economically viable 'green' product. Not only will the use of our new BioBacksheet product allow solar cell manufacturers to reduce cost in an extremely competitive environment, but they will be doing it in a manner that is environmentally responsible. We believe that as consumers demand more 'green' products, solar cell manufacturers will place an even greater value on products such as ours."
