illustrates the process for identifying optimal tandem cell configurations, providing a visual summary of
how to maximize PGD across a wide parameter space. Tang and colleagues developed a HT modeling
approach capable of simulating hundreds of thousands of combinations of device variables, including
thicknesses and bandgaps of the active layers, under various lighting conditions. Their findings
demonstrated that a bifacial perovskite/Cu(In, Ga)Se tandem cell with optimized parameters could achieve
2
a PGD exceeding 495 W/m under high albedo (reflectivity) conditions, outperforming traditional
2
monofacial configurations. The four-terminal configuration, in particular, achieved remarkable
improvements in power output by leveraging the bifacial design to capture light from both front and rear
sides, thus maximizing energy conversion efficiency. This study demonstrates the economic and practical
value of combining tandem and bifacial strategies, especially in high albedo environments such as snowy
areas, where the increased reflected light significantly boosts power output.
