A hybrid CapSA-WHO method used for performance enhancement of tandem perovskite solar cell.

This manuscript proposes a hybrid method for determining the effects of contact-electrode and light-power in tandem perovskite solar-cell (PSC) efficiency. The proposed system combines the Capuchin-Search-Algorithm (CapSA) and the Wild-Horse-Optimizer (WHO), together known as CapSA-WHO method. The proposed work creates the following major contributions: (i) investigating the composition of the tandem Perovskite Solar-Cell (SC) layer; (ii) investigating the effectiveness of PSC depending on Formamidinium and tin; (iii) modelling proficient hybrid solar cells; and (iv) analyzes the performance of the proposed SC. The CapSA-WHO technique is used to examine the effect of absorbent layer materials and optimize the devices. This work also investigated the impacts of various materials, such as hole and transport layers, as well as metal back contact, absorber layer flaws, light radiation power, and so on. Moreover, the influence of temperature variation on absorber layer defect density on solar cell is examined. The proposed CapSA-WHO hybrid method is executed in MATLAB or Simulink site and its performance is compared to existing methods. The system gives an optimal solution with minimal computing time by employing the CapSA-WHO technique. Furthermore, the proposed method discovered minimum fault density to attain maximum device efficiency.
