In this paper, a dual-junction perovskite/CIGS solar cell is designed to use in marine equipment and navigation systems as a renewable energy source. In this design, first, a top solar cell consisting of a perovskite absorber layer with band gap of 1.9 eV is simulated. Then, bottom solar cell is fabricated with a CIGS absorbent layer with a 1.4 eV band gap. Since the perovskite and CIGS band gaps are both adjustable, these two materials can act as a proper partner for an absorbent layer in a dual-junction solar cell. To connect the top and bottom cells, four‐terminal topology is used. In this structure, instead of the usual connection of p-i-n and n-i-p perovskite, n-type and p-type homojunction perovskite connection is used, in which the transfer and separation of carriers are done by an internal electric field. Due to the fact that in this structure, the discharge area is smaller, the recombination of carriers is increased, and the light losses are reduced, which will increase the absorption and efficiency of the cell. The efficiency of the designed dual-junction solar cell is obtained as 30.71%. According to this efficiency and its stability in different environmental conditions, the designed structure can be used in marine equipment and navigation systems as a renewable energy source.
