Conventional screened silver paste is well-established, but leaves room for improvement - literally. Deposition of solid silver within the sintered paste reduces the bulk resistivity and allows improved conductivity with thinner busbars and fingers. Overall efficiency can be increased by 0.3-1.0% with this fast, non-contact electroless silver process. With a small allocation of footprint in an existing PV manufacturing location, the efficiency increase is a low-risk way to lower your cost per watt in the near-term.
Silver deposition using the energy of a PV cell. This unique process relies on light, but not on contact electrodes. No contact means no breakage and perfect plating uniformity acrosss the wafer's surface. Improve fine-line paste printing, or build a full conductor on a seed metal layer. Cyanide-free. The highest conductivity metal deposit.
SUNRISE GLOBAL SOLAR ENERGY REACHED 19.65 PERCENT CELL EFFICIENCY ON PLATING TECHNOLOGY
(Yilan, Taiwan, June 19, 2012) —Sunrise Global Solar Energy Co. Ltd. (Sunrise) has recently achieved a breakthrough for industrial grade p-type Cz solar cells. A peak efficiency of 19.65% was achieved in pilot production by combining Sunrise’s advanced fabrication techniques and a special plating method. The plating technology is using Light Induced Electroless Plating (LIEP) chemicals developed by MacDermid Photovoltaic Solutions (MacDermid). Click here to read more.
