By Editor


LONGi – at the Intersolar Europe 2023 — announced the conversion efficiency of 33.5 percent for silicon-perovskite tandem solar cells based on CZ silicon wafers.

LONGi has achieved conversion efficiency of 33.5 percent for silicon-perovskite tandem solar cells, an increase of 1.7 percent from the previous 31.8 percent, according to the European Solar Test Installation (ESTI).

This was published on the 16th International Photovoltaic Power Generation and Smart Energy Conference & Exhibition (SNEC) in Shanghai. Currently this is the 2nd highest efficiency record in the world and there is a possibility of continuous improvement in the future.

From April 2021, LONGi has broken the world record for solar cell efficiency 14 times, and currently holds the title of achieving the highest conversion efficiency for silicon solar cells at 26.81 percent. Since listing in 2012, LONGi has invested over 20 billion yuan in R&D and has obtained 2,132 patents, Li Zhenguo, President of LONGi, said.

LONGi brought its world-record-holding conceptual product 2681 at this year’s Intersolar Europe. This conceptual product named 2681 weighs 31.8 kg and has a size of 2278 mm × 1134 mm. Its efficiency is based on the advanced technology of 26.81 percent crystalline silicon solar cell efficiency achieved last year. It also has other features like voltage and symmetrical cell structure, and power generation of over 600 W.
