Inkjet printing assisted monolithic interconnection of CIGS using shunt-free laser scribing
conference paper
Monolithic interconnection technology is presented for CIGS using laser scribing and inkjet printing of dielectric and conductive inks. After deposition of all active layers of the CIGS solar cell stack a shunt-free P1 and P3 are laser scribed. A dielectric material is inkjet printed and a P2 scribe is made in between the isolated scribes. In the last step a conductive material is deposited to connect the P2, over the insulating P1 to the front-contact of the neighboring cell. With this back end interconnection technology mini-modules were made using TCO or Ag nanoparticle based inks. The final modules show no electrical losses compared to the reference cells.
