| Abstract: | The material CuInxGa1-xSe2 (CIGS with 0<x<0.3) has attracted much attention,
recently, all over the world as a prospective material for photovoltaic
application. The addition of gallium in CIS (CuInSe2) considerably
improves not only the performance but the stability and efficiency of the
device also. A theoretical analysis of variation of short circuit current
density (JSC) of
polycrystalline solar cell has been reported. As the grain size (dG) and grain boundary
recombination velocity (SGB)
play an important role in deciding device characteristics, the calculations of
the dependence of short-circuits photocurrent density (JSC) have been done on these parameters. The results
show a good agreement with the experimental results. A small discrepancy may be
attributed to the fact that the typical shape of the grains was assumed to be
square-face columnar shaped. |
