“…where Ѱ(x) is the electrostatic potential, e is the electric charge,  0 and  r are vacuum and relative permittivities, p and n are the concentrations of holes and electrons, ND and NA are the donor and acceptor densities, p and n are the distributions of holes and electrons, Jn and Jp are the electron and hole densities, G(x) and R(x) are the generation and recombination rates, respectively. The simulation work for the two designed cells has been done by fitting the standard physical parameters of the materials collected from previously published papers [6,9,10]. All the input parameters are listed in Table 1.…”

The main objective of this work is to investigate the CIGS solar cell performance by replacing the toxic CdS buffer layer from the conventional solar cell structure Ag/ITO/ZnO/CdS/CIGS/W by the non-toxic ZnSe layer using SCAPS-1D software. J-V characteristics of the simulated cell structure show that the efficiency of the solar cell increases from 23.23 % to 23.58 % (with Voc of 0.8202 V, Jsc of 34.86 mA/cm 2 and FF of 82.49 %) due to the use of ZnSe layer. The increase in the efficiency of the cell is attributed to the decrease in photon absorption in the buffer layer due to higher band gap of ZnSe. An additional thin layer was inserted between CIGS and the back contact (W) to eliminate the back surface recombination. This new layer provided an additional hole tunneling action which led to an increase in the solar cell efficiency up to 24.64 %. Moreover, an attempt has been made to investigate the dependence of the CIGS solar cell efficiency on the operating temperature.

“…This material also has a tunable bandgap that is controlled by S and Se contents in the material [2,3,[5][6][7][8][9]22].Copper-indium-gallium-diselenide (CIGS) based solar cells are well known for their special features such as high e ciency, easy fabrication process, low cost, very high durability and stability, exibility and light weight. CIGS hasa high absorption coe cient of 10 5 cm − 1 in the visible solar spectrum and a direct bandgap that varies from 1.04 to 1.7 eV [10][11][12][13].In the fabrication process of solar cells, using a backsurface eld (BSF) layer is a solution to boost the e ciency of the solar cell. BSF layer causes arear pushing force at the highly doped back side of the solar cell and leadstode ectionof the minority carries toward front depletion area.…”

A Back–Surface Field (BSF) CIGS multilayer solar cell structure is simulated by SCAPS–1D in which, a CZTSSe layer is added between BSF and CIGS layers as a second absorber layer. To achieve the best performance for the proposed structure, the thickness of different layers and the related carrier concentration varied. The 1 µm and 0.5 µm thickness for CZTSSe and CIGS leads to the best performance of the device. The optimum thickness for the rest of layers is also calculated. The effect of the carrier concentration on the performance of the proposed solar cell is also studied. After optimization, a solar cell with a privilege power conversion efficiency of 35.1% was achieved.

“…16,17 According to the previous studies on the CIGS efficiency, an exceptional efficiency of 22.9% was achieved, and it was shown that even 27.5% efficiency could be achieved through an optimization process. 18,19 There are ongoing studies about power generation characteristics and efficiency based on new structures, such as graphene film-based CIGS or CIGS deposited on stainless steel substrates. 20,21 Furthermore, the efficiency of CIGS modules can be expected to be enhanced and complemented by successfully developing highly efficient CIGS.…”
