BioSolar Inc. is looking for manufacturers to make its backsheets, a component used on solar panels. Having the manufacturing of the components done elsewhere will allow for Santa Clarita-based BioSolar to focus on development and marketing, said CEO David Lee. “Excess manufacturing capacity exists throughout the world, and many manufacturers are eager to work with fully developed technology products like BioBacksheet,” Lee said in a prepared release. The company anticipates full volume production and delivery to begin this year. BioSolar’s backsheet is made from natural materials instead of petroleum-based materials and eliminates the use of toxins in the manufacturing and disposal process.
