BioSolar Files Patent For BioBacksheet


BioSolar Inc. has filed a patent application to protect the inventions and processes behind its proprietary bio-based backsheet, a protective covering for the back of photovoltaic solar cells traditionally made from expensive petroleum-based film.

The comprehensive patent application is expected to give BioSolar full protection on its BioBacksheet breakthrough technology, which is made from renewable plant sources that will reduce the cost per watt of solar cells, the company says.

Details of manufacturing methods are disclosed in the patent application, which covers many developments, including the use of cellulosic film made from cotton with additives and coatings, and also in combination with a type of nylon derived from castor beans.
