How temperature affects tandem solar cell performance

New outdoor tests conducted at Saudi research center King Abdullah University of Science and Technology (KAUST) have shown that an increase in temperature affects the performance of a tandem perovskite/silicon solar cell not only because of voltage losses but also because of current mismatch between the two sub-cells.


Intense pulsed light processing for 23.0%-efficient silicon heterojunction solar cells

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. ILP processing is roll-to-roll technique for rapid thermal processing of various thin films.

German industry body calls for 5 GW cell manufacturing fab in Europe

The VDMA says Europe can restart a solar production sector that can compete on price with Chinese imports by reducing transport costs – provided a Euro supply chain can be established.
