Integrated solar manufacturer Risen Energy’s Ninghai and Nanbin production bases have received Silver-level ESG certification from the Solar Stewardship Initiative (SSI). The company stated that it has deeply embedded ESG principles into its corporate strategy and operations. Previously, Risen Energy achieved AA ratings from both Wind and Huazheng ESG evaluations. It added that the SSI Silver certification demonstrates its systematic capabilities and consistent performance in sustainability.
In September, Risen Energy secured the ISO/IEC 27001 Information Security Management System and ISO/IEC 27701 Privacy Information Management System certifications (see China Solar PV News Snippets).
Leading BC manufacturer LONGi has begun supplying 400 MW of BC modules for Shanghai Electric Power’s offshore PV project. Located in the sea area of Fengxian District, Shanghai, the project has an installed capacity of 500 MW (AC) and is said to be among the city’s first batch of offshore PV pilot projects, with total investment capped at RMB 3.78 billion ($527 million) by a subsidiary of Shanghai Electric Power.
LONGi highlighted that its BC modules offer higher energy density per unit area, ideal for offshore PV installations where sea-use costs are high and construction windows are short – using BC technology in a 1 GW offshore project can save more than 6.5% of sea area, significantly reducing foundation, cable, and other balance-of-system (BOS) costs. The company added that the modules’ specialized welding and encapsulation design also enables them to withstand typhoons up to Level 17 (60 m/s wind speed) and wave heights of 8 m.
Recently, mid-year performance results from CPVT’s Yantai Offshore PV Demonstration Base showed that LONGi’s 635 W Hi-MO 9 BC modules achieved a 1.94% higher energy yield than 615 W TOPCon modules (see China Solar PV News Snippets).
Nanjing University of Science and Technology announced that a research team led by Professor Xu Bo from the School of Chemistry and Chemical Engineering has developed a new organic hole transport material (HTM). It announced that tin-based perovskite solar cells produced using this material achieved 17.71% power conversion efficiency, setting a new record. The result has been certified by the National PV Industry Measurement and Testing Center (NPVM) and published in Nature under the title Tin-based Perovskite Solar Cells with a Homogeneous Buried Interface.
The study achieved a homogeneous buried interface through molecular design of the organic HTM, significantly improving hole transport efficiency and energy level alignment. It also effectively suppressed non-radiative recombination and material oxidation, overcoming a long-standing bottleneck in the efficiency and stability of eco-friendly perovskite solar cells.
The Gansu Provincial Development and Reform Commission has released the results of the renewable energy mechanism electricity price bidding for June-December 2025, with a total of 61 projects selected, representing a combined electricity volume of 830 million kWh. The selected projects include 43 distributed PV projects (774,574 kWh), 10 centralized PV projects (482,823,834 kWh), and 8 centralized onshore wind projects (346,401,594 kWh). All projects will apply a mechanism electricity price of RMB 0.1954/kWh ($0.0272/kWh), effective for 12 years.
