Santa Clarita-Based BioSolar Working to “Green-ovate” the Solar Power Industry-

The solar industry has crossed major hurdles in the last decade, working diligently to become the idealbiopolymer-thin-film-solar source of green, renewable energy. However, certain obstacles still remain; petroleum engineering in solar cell mechanisms is becoming increasingly more expensive due to constant climbing oil prices and is considered environmentally impure, as it is a form of crude oil. In light of these issues, solar engineers have employed the use of bio-based plastics which are made from all-renewable plant resources. Nonetheless, these manufactured bio-plastics have been unreliable in the past for solar cell purposes because of their delicate molecular composition and low melting properties when exposed to high temperatures; making traditional bio-plastics a wavering option for solar cell fabrication. Dr. David Lee, of BioSolar Inc., has fashioned a solution for standard bio-plastics currently available on the market; introducing a robust protective backing for solar cells derived from cotton and castor beans, which may possibly revolutionize the solar power industry as we know it today. The company, centered in Santa Clarita, CA, is the primary initiator of this resilient bio-based plastic, which substantially reduces solar manufacturing costs and entirely ceases any need for petroleum exploitation. Through the complex manipulation of bio-based materials, BioSolar plans to generate dependable bio-plastics which meet the stringent thermal and durability requirements of current solar cell manufacturing processes. These bio-plastics are expected to cost 25 percent less than Tedlar, the petroleum-based film made by DuPont, which is used by most silicon-based solar cell producers today.

BioSolar materials can be applied in every aspect of solar cell manufacturing such as injection molding and thin film roll-to-roll, module and panel components, as well as superstrate or substrate applications. The company prototype is projected to ease the cost-per-watt utilizing these bio-polymers, whether working with crystalline silicon, amorphous silicon or other solar automation; with the same permanence offered by conventional petroleum-based plastics. Furthermore, by completely eliminating the use of petroleum in solar cells, BioSolar has turned solar into a 100 percent viable resource of green, renewable energy. The company has a two-phase strategy in place to disseminate its inventive bio-plastic materials; first generation films, using robust PLA based superstrate, substrate and backsheet films; and second generation resins, which employ cellulose-based biopolymer resins for non roll-to-roll applications. The company has already released its first product, the ground-breaking BioBacksheet, a 100 percent bio-based substance that forms the bottom layer of most crystalline silicon (c-Si) solar cells – a film usually containing petroleum-based plastics. The BioBacksheet technology will significantly decrease dependency on petroleum and will cost much less than traditional backsheeting, which in turn will lessen consumers’ expense by allowing cell producers to decrease the cost of their finished product. As well as its pioneering BioBacksheets, BioSolar plans to develop a complete line of bio-based products, which will include BioSolar Thin Film Substrate, BioSolar Superstrate and BioSolar Plastics to be used for injection molding in diverse solar panel components. As the market for solar power continues to expand, BioSolar is in an exceptional position to lead the way in development of practical and genuinely renewable solar industrial technology.
