 A comprehensive line of low cost bio-based films and resins to replace higher cost solar cell components: |
BioSolar BacksheetOur line of BioSolar Backsheets, based on our proprietary bio-based materials technology, is designed specifically for c-Si solar cell 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 reduce cost by 50% over traditional backsheet materials.
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 solar cells.
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.
