Method for manufacturing hetero junction type solar cell, involves forming metal interconnects on surface of solar cell by local application of conductive paste and by sintering with laser radiation

摘要

The method involves applying conductive paste (17) containing silver, gold or copper particles by an inkjet process locally on a predetermined region of a surface of a transparent conductive layer (9) on the front side of a solar cell (1). The applied conductive paste is dried at a predetermined temperature, and a sintering is carried out by a laser radiation. A metal interconnect is formed on the surface of the solar cell by the local application of the conductive paste and by sintering with the laser radiation.
