BioSolar Inc. has said that it has successfully completed a scale up
production run of biobased plastic film intended for use as a backing
sheet for photovoltaic cells, which uses 55-inch-wide rolls of film
that exceed the industry maximum width requirement.
“BioSolar has previously developed its biobased polymer which
significantly improves the film’s impact resistance and thermal
performance. The film was successfully extruded at a narrow width. In
order to check for possible scale up problems, we conducted an
extrusion run at the full production width of 55 inches. There were
essentially no scale up problems, and very high quality film was
Durability tests are currently being undertaken

BioSolar is producing bioplastic materials from
renewable plant sources that are designed to reduce the cost per watt
of solar cells.
