Imec announced 27.1 percent on perovskite/silicon tandem cell

Belgian research institute Imec announced a record result for its 4-terminal perovskite/silicon tandem photovoltaic cell. With a power conversion efficiency of 27.1 percent, the new Imec tandem cell beats the most efficient standalone silicon solar cell. »When the perovskite is carefully engineered, the absorbance in the perovskite minimizes the thermal losses that occur in the silicon cell,« says the company. As a result, a perovskite-silicon tandem solar cell »can potentially reach power conversion efficiencies above 30 percent.«
Imec is a partner in Energyville, a collaboration of the Flemish research centers KU Leuven, VITO, Imec and UHasselt in the field of sustainable energy and intelligent energy systems, and a partner in Solliance, a partnership of R&D organizations from the Netherlands, Belgium and Germany working in thin film photovoltaic solar energy.
