Scientists at Germany's Fraunhofer ISE have designed a triple-junction solar cell consisting of perovskite-perovskite-silicon subcells. The device reportedly achieves an efficiency of 20.1% and a remarkable open-circuit voltage of over 2.8 V.Scientists at Germany's Fraunhofer Institute for Solar Energy Systems ISE have demonstrated a triple-junction solar cell with a perovskite-perovskite-silicon subcell configuration. They said the cell achieved an open-circuit voltage of over 2.8 V, which compares to conventional cells with values ranging between 0.7 V and o.8 V. "This is a record value for ...Den vollständigen Artikel lesen ...
