Parameters of additional substrate, including the average absorber thickness, solar cell efficiency and damage voltage for both the dark (DRB) reverse bias sweeps with auto-change and fixed current range. The average values are based on more than 30 measurement points per substrate, the error is the standard deviation. Also in the table is the percentage of cells that were damaged in sweeps with auto-change and fixed current range together with the number of cells (n) used to calculate this damage ratio.
|Substrate||Absorber thickness [nm]||Efficiency [%]||n cells DRB auto-change||DRB auto-change damage ratio [%]||DRB auto-change V damage [V]||n cells DRB fixed-range||DRB fixed-range damage ratio [%]||DRB fixed-range V damage [V]|
