Scientists at Germany's Fraunhofer Institute for Solar Energy Systems (ISE) have used intense pulsed light (IPL) processing for the development of a busbarless silicon heterojunction solar cell. The device was manufactured with poly-Si-based tunnel oxide passivating contacts, which were applied on both sides of the wafer.Researchers at Germany's Fraunhofer ISE have developed a silicon heterojunction (SHJ) solar cell utilizing intense pulsed light-processed screen-printed metal contacts, and claim to have achieved a conversion efficiency of 23.0% with this approach. Instead of commonly utilized ...Den vollständigen Artikel lesen ...
