Researchers from the Photovoltaics and Thin-Film Electronics Laboratory (PV-Lab) in EPFL’s School of Engineering and CSEM have developed a new solar cell that combines exceptional voltage, high efficiency, and scalable manufacturing. The triple-junction device is composed of a silicon bottom cell, onto which middle and top cells made of semiconductors called perovskites are deposited as thin films. The new device, according to the paper published in Nature, achieves an independently certified efficiency of 30.02%, surpassing the previous certified record of 27.1%.
