BioSolar Inc., a developer of a technology to produce bio-based materials from renewable plant sources, plans to expand its BioBacksheet technology to accommodate copper-indium-gallium-selenide (CIGS) and cadmium telluride (CdTe) thin-film modules.
Currently, the company's patent-pending BioBacksheet technology for crystalline silicon (C-Si) photovoltaic solar cells is in the pre-production phase. Designed to replace petroleum-based components with renewable plant sources, the BioBacksheet is a backsheet consisting of a cellulosic film combined with a highly water resistant and high dielectric strength nylon film made from castor beans, the company explains.
‘At present, the C-Si area is the largest photovoltaic market segment,’ says Dr. David Lee, BioSolar chairman and CEO. ‘However, at BioSolar, we recognize that the low-cost potential of thin-film modules, particularly CIGS and CdTe, are emerging as formidable competitors in the global solar market and attracting gigantic investments.’
