AB  - The aim of doing this research is to study and
optimize the parameters I-V and increase the efficiency of
solar cell of CIGS which is a proper substitute for fossil
fuels. This solar cell is a combination of solution of
Cu-Indium-Selenide (CIG) and Cu-Gallium-Selenide
(CGS) which is a kind of semi-conductor of I-III-VI2 that
due to the high stability and the direct band gap Energy
(Eg) is one of the most proper substitutes for silicon solar
cell, also among other solar cells of thin layer, it has
higher efficiency and lower price. In order to realize the
aim of the research, optically modeling and simulating the
solar cells based on thin band of Cu(In,Ga)Se2 (CIGS)
was done by using of Silvaco and AMPS software.
Therefore, the methods of increasing the efficiency of
solar cells of CIGS through improving the thickness of
absorbent layer and changing in impurity of absorbent
layer and adding another absorbent layer (Molybdinum)
and changing in band gap Energy (Eg) of absorbent layers
up to reach to the optimum point were studied. According
to the gained results, the efficiency of 32% of solar cells
of CIGS with minimum effectiveness on other parameters
was gained and a solar cell of CIGS with optimum
structure was created. By gaining the result of similar
simulation by using of AMPS and SILVACO software,
this result was gained that this solar cell practically is
constructible and reliable. Achieving this efficiency can
be a turning-point for more attention of generators of solar
cells to this kind of solar cell.
