BioSolar, Inc, a photovoltaic solar modules manufacturing company, has declared its success in employing bio-based materials manufactured from vegetation in photovoltaic modules to reduce the cost of manufacturing. The bio-back sheet technology, while producing high level surface energy also eliminates the need of back sheet surface treatment process.
The surface energy in a solar module is measured by the dampness of its surface. Solar modules with low level surface energy suffer from the bonding problem with epoxy resins used, while modules with high level surface energy cope well with the surfaces. Most of the conventionally used solar modules incorporate back sheets with low level surface energy and require additional unique surface treatment to augment their surface energy to appropriately bond with the solar cells and film adhesives utilized. The surface treatment process costs more and also run into the risk of panel failure. Also, such surface treatments posed problems during the manufacturing process and product estimating.
The BioBacksheet provided by BioSolar has inherent high surface energy and does not require further surface treatment to bond firmly with the solar cells. The use of BioBacksheets also saves the manufacturers of solar modules from the ordeal of fixing variable costs for providing surface treatment.
Dr. David Lee, CEO of BioSolar, said that the PV industry has attained its maturity level to demand highly productive and durable products from the manufacturers. He added that the potential of BioBacksheets as a cost reducing factor is understood by most of the PV manufacturers, and those who are looking forward to exploit it in their products.
