New world record of efficiency for thin film silicon solar cells

摘要

EPFL's Institute of Microengineering has reached a remarkable 10.7% efficiency single-junction microcrystalline silicon solar cell, clearly surpassing the previous world record of 10.1% held by the Japanese company Kaneka Corporation since 1998. Such significant efficiency, independently certified by the Fraunhofer Institute for Solar Energy Systems (ISE CalLab PV Cells), was achieved in addition with less than 2 micrometres of photovoltaic active material. The Photovoltaics-Laboratory (PV-Lab) of IMT, founded in 1984 by Prof.
