“…The micrographs vividly showcase the pronounced influence of recrystallization temperature on film morphology. Furthermore, both annealing duration and temperature appear to affect the formation kinetics of the CIGSe thin films [37][38][39][40]. The microstructure of the CIGSe thin films displayed variability with respect to selenization time and temperature, as depicted in figures 5(a)-(f).…”

This study aimed to fabricate copper indium gallium diselenide (CIGSe) thin films using a novel two-step approach. Firstly, we deposited metallic precursors (Cu/In/Ga) onto a Mo-coated stainless steel substrate using thermal evaporation at unintentional substrate temperature. Subsequently, selenization was carried out in a furnace under the presence of an inert gas. The quality of the CIGSe thin films was analyzed to explore the influence of selenization temperature (450 °C–550 °C) and duration (30 and 60 min), while maintaining an inert atmosphere inside the selenization furnace. The structural analysis revealed the progressive development of additional phases over time, resulting in the formation of a complete chalcopyrite CIGSe structure with the preferred reflection on the (112) plane. The absorber layer exhibited a thickness of 2 μm, with atomic ratios of 0.83 for Cu/(In+Ga) and 0.24 for Ga/(In+Ga) in the film selenized at 550 °C. P-type conductivity was observed in the CIGSe thin film, with a carrier concentration of up to 1017 cm−3, and it displayed a well-defined and uniform morphology characterized by a large grain size of approximately 0.9 μm. Utilizing the optimized conditions, we successfully fabricated solar cells on a flexible substrate, achieving a photoconversion efficiency of up to 9.91%. This research delves into the impact of selenization parameters on the growth of CIGSe absorber layers and introduces a new approach that could significantly influence the feasibility and industrialization of flexible solar cells.

“…In the present study also, the simulation technique has been applied to determine the variation of the properties critical for the performance of the solar cells. There are lots of experimental [10][11][12], theoretical [13][14][15] as well as computational studies [16,17] about the potential materials that can be used in photovoltaic (PV) solar cells. Availability of computers with high computational powers and many computational packages, it has become relatively easy to carry out simulations prior to any experiment.…”

This article aims to study MoSe2/CIGS tandem solar cells employing SCAPS-1D computational package based on ant colony algorithm. The simulation of Monolithic MoSe2/CIGS tandem solar cells has been implemented successfully by employing the Matlab/Simulink. The power output of the Monolithic MoSe2/CIGS tandem modules increases by the solar irradiations during the first few days of operation. The J-V characteristic and average daily energy production throughout the year has been calculated. The results show 80.71 % FF and 19.29 % efficiency of the solar cell. The other parameter for the ZnO/ZnS/MoSe2 solar cell are Voc = 0.62 V; Jsc = 38.69 mA/cm2.
