Can bifacial solar cells outperform monofacial cells?

Bifacial solar cells can outperform monofacial cells by exploiting sunlight reflected off the ground surface. De Bastiani et al. show that bifacial perovskite/silicon tandem with an optimized bandgap can deliver a power density of 26 mW cm–2 and compare its performance to monofacial cells under outdoor conditions.

Which bifacial architecture has the highest monofacial energy yield?

The highest monofacial energy yield was achieved with a perovskite bandgap of 1.68 and 1.65 eV for both locations, using the identical layer stack of the bifacial architecture and an optimized perovskite thickness.

How do bifacial monolithic perovskite/silicon tandem solar cells work?

Provided by the Springer Nature SharedIt content-sharing initiative Bifacial monolithic perovskite/silicon tandem solar cells exploit albedo—the diffuse reflected light from the environment—to increase their performance above that of monofacial perovskite/silicon tandems.

Do bifacial tandems achieve power conversion efficiencies?

Here we report bifacial tandems with certified power conversion efficiencies >25% under monofacial AM1.5G 1 sun illumination that reach power-generation densities as high as ~26 mW cm–2 under outdoor testing.

Does bifacial tandem perform better than monofacial?

We evaluated the bifacial tandem performance in test-field experiments and predicted the energy yield for bifacial and monofacial tandem configurations in different climates. In both cases, the bifacial tandem outperformed the monofacial configuration, which validates the promise of this technology.
