Advances in Thin Film Technologies for MEMS and Solar

Advances in thin films technologies are transforming traditional manufacturing processes and whetting the appetite of industry.Multiple new techniques in thin films technology are vying for supremacy in two rapidly growing sectors—microelectromechanical systems (MEMS) and highly-efficient photovoltaic systems.

Silicon wafer-based cells may soon give way to a new generation of thin film photovoltaics. According to The Information Network, a New Tripoli, Pa.,-based market research company for the semiconductor industry, manufacturing methods using cadmium telluride, CdTe, and copper indium gallium selenide, CIGS, will see a tremendous boost in research dollars for future equipment manufacture. A 275% increase in investment by 2010 is expected, which is a testament to their anticipated impact.CIGS and CdTe rely on the deposition of nanoparticles of the precursor materials on the substrate, followed by in-place sintering. The U.S. Dept. of Energy's National Renewable Energy Laboratory, Golden, Colo., says the best CIGS cell now matches the efficiency of the best polycrystalline-silicon cell, about 19.5% efficiency. Potential applications include newspaper-like roll-to-roll printing and CIGS-based inks.

Dear sir/maddam
I deposited CdTe on Si and BK7(schott glass)with PVD method(heat resistant evaporator). I have many problems with this thin film. Adhesion of this film is not good.
would you please help me?
