Abstract
With the development of photovoltaic industry, the cost of photovoltaic power generation has become the signifi cant issue. And the metallization process has decided the cost of original materials and photovoltaic effi ciency of the solar cells. Nowadays,double printing process has been introduced instead of one-step printing process for front contact of polycrystallinesilicon solar cells, which can eff ectively improve the photovoltaic conversion effi ciency of silicon solar cells. Here, therelative cheap Cu paste has replaced the expensive Ag paste to form Ag/Cu composite front contact of silicon solar cells. The photovoltaic performance and the cost of photovoltaic power generation have been investigated. With the optimizationon structure and height of Cu fi nger layer for Ag/Cu composite double-printed front contact, the silicon solar cells haveexhibited a photovoltaic conversion effi ciency of 18.41%, which has reduced 3.42 cent per Watt for the cost of photovoltaicpower generation.
