The research group led by Professor Martin Green has published version 62 of the solar cell efficiency tables. In the new version, 21 new results have been reported, which is a record number in the tables.
“Highlights include a large increase in efficiency from 13.0% to 14.9% for small-area kesterite cells (CZTSSe) by the Institute of Physics of the Chinese Academy of Sciences (CAS), and a less dramatic increase in efficiency for small-area organic PV cells. 19.2% Shanghai from Jiao Tong University and the efficiency of small-area perovskite cells to 26.0% at the Institute of Semiconductors, CAS, Green said. pv magazine.
“Significant perovskite advances have also been reported in the area of 2-terminal tandem cells, with all-perovskite tandem cell efficiency increasing to 29.1 percent in a 0.05 cm2 device and 28.2 percent in a larger 1 cm2 device. Both devices are manufactured by Nanjing University in collaboration with Renshine Solar,” he added.
Greener also pointed out that new results have been reported for perovskite/silicon tandem cells with 33.7% efficiency in a 1 cm2 King Abdullah University of Science and Technology (KAUST) device and 28.6% efficiency in a much larger, full-size device. 258 cm2 cell manufactured by Oxford PV.
“Good progress has also been reported in the area of encapsulated modules, with organic PV module efficiency increasing significantly from 8.7% to 13.1% in a 57-cell module manufactured by Ways Technical Corporation in conjunction with Nanobit,” he explained. “Efficiency improvements of up to 19.2% have also been reported for a 39-cell perovskite module manufactured by UtmoLight and up to 24.7% for a much larger 112-cell, 1.8m2 silicon module manufactured by Maxeon. Additionally, Avancis’ first small CIGS module , with an efficiency of more than 20%, has been reported.”
In the table version 61 published in November, the researchers added five new results. The group has seen significant improvements in all cell classes since 1993, when the tables were first published.
