PETROLEUM FREE: A new backsheet for solar cells is created from cotton and castor beans rather than petroleum-based plastics.
BioSolar, Inc. has developed a breakthrough technology to produce bio-based materials from renewable plant sources that will reduce the cost per watt of solar cells. Most of the solar industry is focused on photovoltaic efficiency to reduce cost. BioSolar is the first company to introduce a new dimension of cost reduction by replacing petroleum-based plastic solar cell components with durable bio-based components.
Through the advanced manipulation of bio-based polymers, BioSolar intends to produce robust bio-based components that meet the stringent thermal and durability requirements of current solar cell manufacturing processes. BioSolar materials can be used directly in conventional manufacturing systems, such as injection molding and thin-film roll-to-roll, to create superstrate layer, substrate layer, backsheet as well as module and panel components.
Whether solar cells are produced using crystalline silicon, amorphous silicon or other solar technologies, BioSolar can help reduce the cost per watt through the use of its lower cost bio-based materials.
By removing petroleum from solar cells, BioSolar makes solar energy a true green source of energy.
Hows its made:
The bio-based components are a composite of cellulosic material derived from cotton, combined with an arcane nylon (nylon 11) derived from castor beans. The two sustainably sourced components are combined utilizing the company's proprietary manufacturing process.
BioSolar starts with used cotton rags and turns them into a film of cellulose a natural fiber. They then blend this film with a type of nylon made from castor beans by Philadephia-based Arkema, Inc. to make the so-called BioBacksheet. Initial testing by the company at the National Renewable Energy Laboratory shows that this flexible plastic backsheet lasts as long or longer than conventional ones, and keeps out just as much moisture.
In addition to keeping away from petroleum plastics, BioSolar also claims not to be using any genetically modified crops in its product-a further boost to its green credibility. But nearly 90 percent of the U.S. cotton crop is so altered, either to resist insects, herbicides or both, according to the U.S. Department of Agriculture. And cotton cultivation still requires tons of pesticides and fertilizers, both of which are derived, in part, from petroleum.
Regardless, if the used cotton and castor oil-based backsheet proves cheaper than the petroleum version it may help remove a bit more fossil sunshine from the new solar energy. "Our goal is to replace all the petroleum plastic out of the solar cells with this bio-based one," Lee says. "The real merit is that we can actually reduce the cost of the backsheet compared to conventional petroleum-based backsheet." Lee claims their backsheets will cost 25 percent less than conventional backsheets, which cost between $0.70 and $1 per square foot.
BioSolar is developing a comprehensive line of bioplastic films and resins for solar cell manufacturers, based on its breakthrough bioplastic technology. There are primarily two kinds of solar cells in the market today: traditional crystalline silicon (c-Si) and thin film solar cells. While thin film technology promises lower cost and more efficient manufacturing, it still represents a very small part of the solar cell market. Traditional c-Si solar cells command 94% of the market today while thin film and other non-c-Si solar cells are projected to grow to only 8% by 2010.
Our product roadmap is designed to align BioSolar with market opportunities. Whether solar cells are produced using crystalline silicon, amorphous silicon or other solar technologies, BioSolar can help reduce the cost per watt through the use of its lower cost bioplastics.
* BioSolar Backsheet
* BioSolar Thin Film Substrate
* BioSolar Superstrate
* BioSolar Plastic
BioSolar is in a very unique position within the supply chain to provide the entire solar industry, including next generation thin-film manufacturers, further cost reductions through the use of its breakthrough bio-based materials.
Our 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.
Biosolar Thin-Film Substrate:
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.
