The US Department of Energy’s National Renewable Energy Laboratory (NREL) has up to date its Best Research-Cell Efficiency Chart with the inclusion of a brand new cell class – Hybrid Tandems.

“This class collects data of tandem cells with layers composed of two completely different PV supplies. Some subcategories of Hybrid Tandems (Perovskite/Si and Perovskite/CIGS) exist already within the earlier format beneath ‘Emerging PV,’ whereas others (III-V/Si and Perovskite/natural) are new,” the analysis institute stated in an announcement. “All of those subcategories have been moved to the brand new Hybrid Tandems class—aside from perovskite/perovskite tandems, that are listed beneath Emerging PV.”

NREL highlights that each one of those modifications are actually displayed in an interactive chart. The instrument highlights the very best confirmed conversion effectivity of analysis cells for a variety of PV applied sciences.

“Everything till the tip of 2023 is included,” a spokesperson from the analysis institute not too long ago stated pv journalit’s famous that the chart additionally consists of necessary outcomes achieved within the first quarter of this 12 months.

Today’s chart consists of the 33.9% world document effectivity achieved in November by Chinese producer Longi for a perovskite-silicon tandem photo voltaic cell and the 27.09% effectivity achieved by the identical firm for heterojunction again contact photo voltaic. cell. Additionally, it consists of the 23.64% effectivity achieved in March by US-based thin-film module maker First Solar for a photo voltaic cell primarily based on copper, indium, gallium and diselenide expertise ( CIGS).
