BioSolar Reports Successful Pilot Run of New BioBacksheet-A for Thin-Film Solar Cells

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, announced the successful prototype run of the new BioBacksheet^TM-A product featuring absolute moisture barrier for the thin-film solar cell market. The announcement follows BioSolar’s recent news that the BioBacksheet-C, designed for the traditional C-Si PV modules, will be the company’s first product commercially available during the later half of 2009.

BioSolar’s chairman and CEO Dr. David Lee recognizes that the fastest growing segment of the photovoltaic (PV) market is thin film, particularly copper-indium-gallium-selenide (CIGS) and cadmium telluride (CdTe) thin-film photovoltaic panels, requiring backsheets with a challenging water vapor transmission rate of nearly zero.

“BioSolar has accepted this challenge, and has developed our BioBacksheet-A with absolute moisture barrier with green components,” said Lee. “The three layer laminate film consisting of 100 percent recyclable aluminum foil is the center core sandwiched between outer layers of bio-based polymer films, making our product unique in the industry.”

“The initial pilot line run, a scaled down prototyping run, of the BioBacksheet-A was highly successful, and samples of this product will be subjected to extensive list of testing once initial evaluation of the backsheet on modules is complete,” said Lee.

BioSolar’s line of proprietary BioBacksheet protective coverings are designed to replace expensive and hazardous petroleum-based film with a bio-based one, creating a more environmentally-friendly and cost-effective solar panel component. BioSolar’s bio-based materials – both individually and in combination – meet or exceed the characteristics of various testing and performance standards for the photovoltaic industry.”
