Founded in 2000, LONGi Green Energy Technology Co., Ltd. (LONGi) is a solar technology that develops solutions for large-scale power plants and for different industries and households with its innovation-focused development. Eventually, it also plans to supply "Green Power + Green Hydrogen" solutions for global zero-carbon development.
Since 2015, LONGi has located its operations in Yunnan, China, and Kuching, Malaysia, to utilize the abundant local hydropower resources to provide clean energy for its facilities. LONGi plans to integrate solar power plants with pumped storage in areas that feature significant elevation differences and abundant sunlight, creating an industrial model for using solar.
On its website, LONGi states that "the LONGi R&D team has achieved successive breakthroughs in key technologies. These include perovskite thin-film crystal growth on textured silicon substrates, high-efficiency bulk passivation and optical management, and these advancements have led to rapid improvements in the efficiency of silicon-based stacked cells".

LONGi announces new world record efficiency of 30.1% for commercial M6 size wafer-level silicon-perovskite tandem solar cells
LONGi Green Energy Technology has announced a new world record efficiency of 30.1% for a commercial M6 size wafer-level silicon-perovskite tandem solar cell at the 2024 Intersolar Europe event in Germany. This new record comes less than a week after LONGi announced a new world record of 34.6% tandem solar cell efficiency at the 2024 SNEC EXPO in Shanghai, and it also breaks the previous world record of 28.6% wafer-level tandem solar cell efficiency on M4 commercial size wafers in May 2023.
The commercial M6 size wafer-level silicon-perovskite tandem solar cell was independently certified by the Fraunhofer Institute for Solar Energy (Fraunhofer ISE) in Germany.
LONGi announces 34.6% efficiency record for its perovskite-silicon tandem solar cell
Reports suggest that LONGi has announced that it has reached 34.6% efficiency for a perovskite-silicon tandem solar cell, at the SNEC tradeshow in Shanghai, China.
The European Solar Test Installation (ESTI) reportedly certified the results, which represent a world record for this cell type. The previous record was held by LONGi itself, which achieved an efficiency of 33.9% in November 2023.
LONGi announces 33.9% conversion efficiency record for its silicon-perovskite tandem solar cells
Reports suggest that LONGi Green Energy Technology managed to reach a conversion efficiency of 33.9% for its silicon-perovskite tandem solar cells.
The result, currently the highest efficiency record in the world for a perovskite/silicon tandem cell, has reportedly been confirmed by the US National Renewable Energy Laboratory (NREL).
National University of Singapore and REC Solar launch US$57.4 million solar research initiative
The National University of Singapore (NUS) and REC Solar, the solar power arm of the Singaporean Renewable Energy Corporation, have launched a S$77 million (US$57.4 million) solar cell research initiative.
The project, called the REC@NUS Corporate R&D Laboratory for Next Generation Photovoltaics, will be led by two co-directors, professor Amrin Aberle, CEO of the NUS’ Solar Energy Research Institute of Singapore, and Shankar G Sridhara, chief technology officer of REC Solar. The university announced that the initiative will develop and commercialize “disruptive” PV technologies, based on perovskite-silicon tandem solar cells in particular.
LONGi announces conversion efficiency of 33.5% for silicon-perovskite tandem solar cells based on commercial CZ silicon wafers
LONGi announced new conversion efficiency of 33.5% for silicon-perovskite tandem solar cells based on commercial CZ silicon wafers, as was revealed at the Intersolar Europe 2023 exhibition. Earlier this month, LONGi announced its “STAR Innovative Ecological Cooperation Platform” and its newly achieved efficiency of 31.8% for perovskite/crystalline silicon tandem solar cells based on commercial CZ silicon wafers.
“Improving cell conversion efficiency and reducing the cost of electricity remain the perpetual theme driving the development of the photovoltaic industry.” Said Li Zhenguo, President of LONGi.
