Nowadays, thin-film solar cells are increasingly used mainly because of their low cost. In recent decades, the performance of these cells has improved significantly. In this work, we simulated a CIGS-based solar cell using new software (SCAPS) to analyze certain parameters. In particular, properties (capacity, capacity derivative, mid-height strip width, parallel resistance and others...) play a crucial role in cell performance, and in order to optimize it. We studied under polychromatic illumination (from 400 nm to 900 nm) their influence on the quantities of the solar cell. In order to highlight the importance of depositing an absorbent layer of the CIGS type on solar cells. The recorded energy efficiency increased from 32.85% to a wavelength of 900 with a form factor FF=80.11% and a form factor FF=81.42% at a wavelength of 600 nm for an efficiency of 23.24% nm. And at this wavelength of 600 nm, we also have a parallel resistance of 2846.9 ohm /cm2. The results obtained are in very good agreement with the published experimental results.
