The US Division of Power’s Nationwide Renewable Power Laboratory (NREL) has up to date its Greatest Analysis-Cell Effectivity Chart with the inclusion of a brand new cell class – Hybrid Tandems.
“This class collects report tandem cells with layers composed of two totally different PV supplies. Some subcategories of Hybrid Tandems (Perovskite/Si and Perovskite/CIGS) have been already current within the earlier format underneath ‘Rising PV,’ whereas others (III-V/Si and Perovskite/natural) are new,” the analysis institute mentioned in a press release. “All of those subcategories have been moved into the brand new Hybrid Tandems class—excluding perovskite/perovskite tandems, that are listed underneath Rising PV.”
The NREL harassed that each one these modifications are actually mirrored within the interactive chart. The instrument highlights the best confirmed conversion efficiencies of analysis cells for a variety of PV applied sciences.
“Every thing as much as the tip of 2023 is included,” a spokesperson from the analysis institute not too long ago instructed pv journal, noting the chart additionally contains necessary outcomes achieved within the first quarter of this yr.
The chart now contains the 33.9% world report effectivity achieved in November by Chinese language producer Longi for a perovskite-silicon tandem photo voltaic cell and the 27.09% effectivity achieved by the identical firm for a heterojunction again contact photo voltaic cell. Moreover, it contains the 23.64% effectivity achieved in March by US-based thin-film module maker First Photo voltaic for a photo voltaic cell primarily based on copper, indium, gallium and diselenide (CIGS) know-how.
