Perovskite manufacturer UtmoLight has signed a strategic cooperation agreement with Wuxi Xingyuan Green Energy Co., Ltd., a subsidiary of Wuxi Energy Group, to promote commercial applications of perovskite PV.
Under the agreement, the 2 parties will utilize UtmoLight’s perovskite PV technology in building-integrated photovoltaics (BIPV), zero-carbon industrial parks, and PV power plants. The first project under the partnership will be a 6.7 MW rooftop distributed PV plant, which UtmoLight says will be the largest single commercialized perovskite rooftop project to date.
In July, UtmoLight announced that 2 of its projects have been included in Jiangsu Province’s 2025 Urban and Rural Development Special Fund under the Green Building category (see China Solar PV News Snippets).
LONGi has recently published 2 major research papers in the scientific journal Nature.
The first study, titled Flexible perovskite/silicon tandem solar cell with a dual buffer layer, developed jointly with Soochow University and Xi’an Jiaotong University, achieved a certified efficiency of 33.4% for a small-area ultrathin crystalline silicon-perovskite tandem cell, verified by the US National Renewable Energy Laboratory (NREL). A flexible, commercial-size silicon-wafer-based tandem cell also reached 29.8%, certified by Germany’s Fraunhofer ISE. LONGi noted that this represents the world’s first and only flexible crystalline silicon-perovskite tandem cell efficiency record certified by international authorities.
The second paper, titled Silicon solar cells with hybrid back contacts and published in collaboration with Sun Yat-sen University and Lanzhou University, reports a 27.81% efficiency record for a single-junction crystalline silicon cell using a hybrid amorphous-polycrystalline back-contact (HIBC) structure. According to LONGi, this new HIBC architecture is a Chinese-originated high-efficiency cell concept with fully independent intellectual property and significant technical barriers.
Last month, LONGi’s Hi-MO X10 lightweight PV module received Grade AAA certification from TÜV Rheinland (see China Solar PV News Snippets).
The Jiangsu Provincial Development and Reform Commission has announced a mechanism tariff bidding process for new energy projects that will achieve full grid connection between June 1, 2025, and December 31, 2026.
According to the notice, bidding will be held for a total mechanism power volume of 13 billion kWh, including 1 billion kWh from offshore wind power and 12 billion kWh from other wind and PV projects. For onshore wind and PV projects, the ceiling price is set at RMB 0.391/kWh and a floor of RMB 0.25/kWh, with a 10-year execution term. For the offshore wind portion, the price range is RMB 0.3 to RMB 0.391/kWh, effective for 15 years.
Zhejiang Province has also announced plans to conduct competitive bidding for new energy projects under the mechanism electricity pricing scheme.
According to the provincial Development and Reform Commission, the bidding targets 2 categories: (1) projects connected at 110 kV or above with a capacity of 40 MW or more that achieve full grid connection between June 1 and December 31, 2025; and (2) certain designated projects completing grid connection between June and November 13, 2025.
This round of bidding covers only PV projects, with a total scale of 1.474 billion kWh. The declared price range is RMB 0.242 to RMB 0.393/kWh, valid for 12 years. The results are scheduled to be announced on December 5.
