SANTA CLARITA, USA: BioSolar Inc., a developer of a breakthrough technology to produce bio-based materials from renewable plant sources that reduce the cost of photovoltaic solar modules, announced that the company has recently filed a patent application to protect the innovations behind its proprietary BioBacksheet-A, a bio-based backsheet featuring an absolute moisture barrier for the thin-film solar cell market.
BioBacksheet-A is a three layer laminate film consisting of a 100 percent recyclable aluminum foil center core sandwiched between two outer layers of bio-based polymer films, making it a unique product in the industry.
“BioSolar's goal is to reduce the costs of solar modules and make solar energy greener by replacing petroleum-based module components with bio-based materials made from renewable plant sources,” said Dr. David Lee, CEO of BioSolar. “Patent filing and protection of our intellectual property is an important milestone as we continue our journey toward full-scale commercial production for many of the company’s new products.”
This patent filing follows the recent news that BioSolar has not only accepted the challenge of developing a backsheet with a water vapor transmission rate of essentially zero, which is necessary for thin film solar module components such as cad-telluride and CIGS, but also the initial pilot line run of this backsheet was highly successful. Testing of these samples continues as the company moves toward commercialization.
BioSolar’s complete line of backsheets meet or exceed the characteristics of various testing and performance standards for the photovoltaic industry and are expected to cost significantly less than petroleum-based films currently in use by the majority of solar module manufacturers today.
