A comprehensive line of low cost bio-based films and resins to replace higher cost solar panel components:

Our first commercially available line of BioSolar Backsheets, based on our proprietary bio-based materials technology, is designed specifically for c-Si PV module manufacturers. These backsheets will be available in rolls of film for direct use in lamination and roll-to-roll assembly systems. We estimate that using BioSolar Backsheets can substantially reduce cost over traditional backsheet materials of similar properties.

With the growth of the thin film solar cell market, we are undertaking research and development efforts on a modified version of our bio-based materials for use in thin film substrates. In thin film processing, the layers of a solar cell are deposited on top of a substrate and built up instead of laminating the completed cell.

Therefore, the thermal and mechanical requirements for thin film are different than those for c-Si. Currently available thin film substrates are primarily stainless steel or petroleum-based plastics, generally very expensive materials. We anticipate that with the proper enhancements to bio-based materials, we can deliver a bio-based substrate to thin film manufacturers for use in roll-to-roll chemical vapor deposition (CVD) processes.

The top layer of a solar cell is traditionally made of glass or other specialty non bio-based polymers. The solar industry consumes as much top layer as backsheets and substrates. We believe that a transparent bio-based material can be produced to replace this layer to further reduce the cost of current and next generation PV solar modules.

To complete our portfolio of bio-based offerings, we also anticipate developing a line of bio-based resins for injection molding applications in creating various housing and packaging components for solar panels and arrays.
