A Comprehensive Review of Tandem Solar Cells Integrated on Silicon Substrate: III/V vs Perovskite

Abstract High-efficiency solar cells with low manufacturing costs have been recently accomplished utilizing different technologies. III-V-based tandem solar cells have exhibited performance enhancement with a recent efficiency of greater than 39% under AM1.5G and 47% under concentration. Integration of such III-V materials on a relatively cheap Silicon (Si) substrate is a potential pathway to fabricate high-efficient low-cost tandem solar cells. Besides, perovskite solar cells, as third-generation thin film photovoltaics (PV), have been meteorically developed at a reasonable cost. At present, there are still questions for cost reduction of perovskite materials and solar cell modules because of their limited commercialization. In this review, stacking Si solar cells with III-V material to form Si-based III-V tandem solar cells is presented with different integration technological routes. Also, perovskite/Si tandem solar cells have been reviewed alongside their main engineering challenges introduced through the fabrication of perovskite-based tandem solar cells. Finally, a comparison between III-V tandem solar cells, Si-based III-V tandem solar cells, and perovskite-based tandem solar cells is introduced so that the best technology for a specific application could be determined. The review provides a comprehensive study of two different technologies (III/V and Perovskite) to demonstrate the most valuable cost reduction availability for each.
