KAUST researchers involved in raising bar for solar energy harvesting Two-sided solar cells collect indirect light to break efficiency records
Published in The Saudi Gazette on 12 - 01 - 2021

To increase the performance of solar panels, an international collaboration — including researchers from King Abdullah University of Science & Technology (KAUST) and U of T Engineering — has created a bifacial, or two-sided, tandem solar cell, built by bringing together the best of the perovskite and silicon technologies.
Out in the field, light primarily comes directly from the sun. Conventional tandem solar cells can already convert this light into electricity more efficiently compared to traditional silicon-only solar cells by absorbing additional wavelengths of light.
Now, the researchers have realized that even more energy can be gathered using a two-sided tandem configuration. Light reflected and scattered from the ground — referred to as "albedo" — can also be collected to significantly increase the current of a tandem solar cell.
The research, which was published Tuesday in the journal Nature Energy, outlines exactly how the team engineered the perovskite/silicon device to exceed the currently accepted performance limits for the tandem configuration.
"By exploiting the albedo" Dr. Michele De Bastiani, the co-lead author of this study, said, "We can now generate currents higher than in conventional tandems, without increasing the manufacturing costs at all."
The potential for capturing indirect sunlight has been studied in the past, but without experimental verification.
KAUST researchers, working with collaborators from the University of Toronto, the Karlsruhe Institute of Technology, and the University of Bologna, were able to solve the scientific and engineering challenges required to include indirect sunlight in the energy gathering capacity of their modules.
With this knowledge at hand, they tested the bifacial tandem solar cell in outdoor conditions, achieving efficiencies beyond any commercial silicon solar panel.
"Bifacial silicon-only solar cells are rapidly taken an increasing share in the photovoltaics market, as they can lead to a performance gain of 20% relative.
"Exploiting this concept in perovskite/silicon tandems now opens opportunities for ultra-high power generation at affordable cost" concluded Professor Stefaan De Wolf. — SG
