Abstract :
Crystalline silicon solar cells with laser-fired contact (LFC) are simulated with Crosslight APSYS and CSUPREM. Different laser firing parameters lead to different LFC profiles and different cell performances. It is shown that the cell efficiency can be improved to a relatively stable value by increasing concentration of aluminum clusters, lasing time or laser spot diameter. The results are further explained quantitatively by dark current and qualitatively by built-in potential.
