DuPont says its metallization paste increases solar-cell efficiency.

Chemical makers are ramping up to meet strong growth in the solar industry. DuPont will double capacity for its Solamet photovoltaic metallization pastes. To be completed in 2011, the expansion involves facilities in Manati, P.R.; Dongguan, China; and Taoyuan, Taiwan. 3M will double capacity at a Singapore plant that makes Scotchshield, a barrier film used in photovoltaic modules.
