摘要

The best conversion efficiency of champion, small-area CIGSeS cells and mass-produced modules are 20.3% and ～12.0% respectively. Molybdenum back-contact layer is scribed with a laser (P1). Development of laser scribing for P2 and P3 scribes will reduce the dead area and improve the reliability. Development of a laser annealing technique can minimize and passivate micro-non-uniformities and grain boundaries thus reducing carrier recombination. In-situ characterization of the sample through a nonintrusive method such as reflectivity measurement during the laser recrystallization process can enhance insight into laser-material interaction and the effect of material structures on the photoelectric properties of solar cells. The improvement in efficiency achieved with laser processing can help to bring down the cost.
