Biosolar Completes Run of Thin-film Backsheet

BioSolar Inc. said this week that is has completed a prototype run of the new BioBacksheet-A, which features an absolute moisture barrier, for the thin-film solar cell market. The announcement follows BioSolar’s recent news that its 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 said that it 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. 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,” said David Lee, Biosolar’s CEO. “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.”
