All photo voltaic cell efficiencies at a look – up to date – pv journal International


The analysis group led by Professor Martin Green has revealed Version 64 of the photo voltaic cell effectivity tables. There are 19 new outcomes reported within the new model.

An worldwide analysis group led by Professor Martin Green from the University of New South Wales (UNSW) in Australia has revealed Version 64 of the “photo voltaic cell effectivity tables” in Advances in Photovoltaics.

The scientists stated they added 19 new outcomes to the brand new tables since December.

Strong progress has been reported throughout photo voltaic cell applied sciences together with silicon, chalcogenide, natural and perovskite.

A serious new result’s the 27.3%-efficient n-type silicon heterojunction interdigitated-back-contact (HBC) photo voltaic cell that Chinese producer Longi unveiled in late May. “The cell, which establishes a brand new direct report for silicon, has the identical polarity contacts on the again aspect that stops loss by lack of contacts on the entrance radiating floor,” reads on paper. “All laser patterning processes are used for the extra advanced again floor patterning required for such gadgets.”

Another result’s the 34.2% energy conversion effectivity achieved by Longi for the perovskite-silicon tandem photo voltaic cell in April with an up to date worth of 34.6% obtained in May held in reserve and reported on the Shanghai New Energy Conference (SNEC) in June.

The listing additionally features a 25.6%-efficient large-area n-type TOPCon cell made by JA Solar, a 26.8%-efficient large-area n-type silicon cell made by Longi, and the 24.9% effectivity achieved by Singapore-based Maxeon. for its IBC photo voltaic module.

Additionally, the tables now embody the 22.6% effectivity achieved by US-based First Solar for a 0.45 cm2 cadmium-telluride (CdTe) cell, in addition to many different thin-film photo voltaic cells. cells primarily based on kesterite (CZTSSe) or copper, gallium, indium, and diselenide (CIGS). These embody reaching the 15% effectivity milestone for small-area CZTSSe cells developed by the Chinese Academy of Science and a full-size 0.8 m2 perovskite module developed by Microquanta that based by former UNSW college students.

In Version 63 of the tables, launched in December, the researchers added 6 new outcomes. The group has seen main enhancements in all cell classes since 1993, when the tables had been first revealed.

The analysis group contains scientists from the European Commission Joint Research Center, Germany’s Fraunhofer Institute for Solar Energy Systems and the Institute for Solar Energy Research (ISFH), Japan’s National Institute of Advanced Industrial Science and Technology, and the US National Renewable Energy Laboratory.
