Heraeus Advanced Metallization Pastes For High Efficiency Solar Cells using Poly-Silicon Passivated Contacts Updated On Wed, Sep 26th, 2018 by Saurenergy The highest efficiency solar cell to date with metal contacts on both sides (not IBC) is the TOPCon cell structure developed by Fraunhofer ISE. They currently hold the world record efficiency of 25.8% with an impressive Voc of 724mV [1]. The key differentiator of this cell is the addition of a thin tunnel oxide with […] Read more
Fraunhofer Sets New World Record for Multicrystalline Silicon Solar Cell with 21.9 Percent Efficiency Updated On Mon, Feb 20th, 2017 by Saurenergy The record Multicrystalline Silicon solar cell consists of n-type high performance multicrystalline silicon, or HP mc-Si. Compared to p-type silicon, this material shows a higher tolerance to impurities, especially iron. Researchers at Fraunhofer ISE have produced a multicrystalline silicon solar cell with 21.9 percent efficiency, which successfully brings the world record back to Freiburg. Higher […] Read more
